Spray Painting

Home interiors and exteriors are usually painted with a combination of a brush and roller. Other painting projects are best done with spray paint.

Spray painting is a good option for small or moderate sized painting projects. It is also good for some large projects like cars, though this would require professional equipment. With a moderate amount of skill spray painting can achieve good, smooth results in minimal time.

Spray Paint Cans

Professional spray painting uses an airgun and compressor, equipment most people do not have. But most spray painting is done with spray paint cans bought from the local hardware store.

The spray procedure is reasonably straightforward.

  • Always paint in a well ventilated place. Outdoors in the open is best.
  • Clean the surfaces that you wish to paint. Remove all grease and wait to dry.
  • Cover any part of the object that is not mean to be painted. Use masking tape and newspaper.
  • Use an appropriate primer. There are different primers for timber, metal, ceramic. Follow instructions on the back of the primer can.
  • Shake the spray can for a minute before using, to mix the paint well.
  • Hold the spray can 30 cm from the surface you are painting, spraying lightly with several passes. Passes should overlap by one third
  • You can have several coats of paint. Make each coat is quite light, do not let the paint get thick.
  • The layer of paint will need to dry between coats. Look at the drying time on the paint can instructions.
  • Consider a clear protective coat at the end.

IMPORTANT – each time you finish a coat of paint you will need to clear the spray nozzle. Do this by holding the can upside-down and spraying until only air comes out.  This should only take a few seconds.

Having your home professionally painted will provide the backdrop for your preferred décor. Consider renovating some furniture to achieve that décor look. DIY spray painting can be very good for some home furniture projects.

Distressed Painting

House Painters Sydney

The furniture is an obvious part of a home’s décor. Along with the wall paint and flooring material it is part of the overall, and hopefully coherent, look of a room.

Sometimes furniture is painted to make is suitable for the home décor. This is a great way to restore old furniture or make use of cheap furniture found in a garage sale.

One restoration option is to make the furniture look pristine and new. This is possible if the furniture originally had a painted finish. But it is difficult to achieve because it requires professional techniques and materials.

An alternative to complete restoration is to replicate a classic look by synthetic means. One example it to create and artificial woodgrain pattern on wooden furniture. This can be done by painting a dark colour over a lighter colour and using a graining tool (a roller with a 3D pattern) on the still wet paint. Alternate, you can use a light paint over a dark undercoat.

With the woodgrain paint it is possible to turn a cheap wooden object, even pine or plywood, into a piece of furniture that looks like expensive timber.

Distressing Paint

Another alternative to pristine finishes is distressed paintwork. This is deliberately making a piece of paintwork look old and weathered. This can suit several different decors from rustic (darker painted furniture in an old style room) to sparse pascal décor (light pastel coloured furniture in an open, modern room).

Painted furniture can be distressed by sanding back and removing some of the paint. Or they can be coloured with thin, semi-transparent paint that shows the underlying grain.

Distressed furniture can be enhanced by gold leaf trim, which itself make be made to suit the furniture by being distressed.

Chalk paint is popular for some type of furniture restorations. This is paint with an additive that makes the surface appears powdery, like plaster or chalk. It is smooth but not glossy. This is particularly effective with pascal colours.

Brush Types

House Painting Sydney

Most indoor painting is done with a roller. But corners and small details are painted with a brush. The type of brush used will affect the look of the painted finish.

Bristles.

Perhaps the most important difference between brushes and the affect they have on the final paint project. Thin bristles brushes will give a smoother coat of paint, but long bristles will not stay straight if they are too thin. So tapered bristled, which grow thinner near the tip, give the best of both worlds. Tapered bristles are sufficiently rigid while giving the smooth finish of thin bristle brushes.

Synthetic vs Natural bristles

Synthetic bristles are a more recent invention. They may be made of polyester and/or nylon, and are quite long lasting. They may also be tapered or completely straight. These synthetic brushes are preferred for water based paints as they do not expand when wet.

Natural bristles are preferred for oil based paints and varnishes. These natural material are not affected by the oil or thinner in the paint, and produce a smoother paint finish than almost any other brush.

Brush shape

There are different ways the bristles of a brush may be shaped. The more common varieties are:

Flat – A common variety. The bristles are arranged in a rectangular shape. This is used for most painting.

Tapered – The bristles are long in the centre and slightly tapers towards the edge. Many professional painters find this improves their control.

Angled –The bristles will slope from left to right of the brush. This is very useful for painting edges, which exist in all indoor painting situations.

Brush Size
Metric brushes vary between 10mm, 20mm, 40mm, 50mm up to 100 mm.

Faux Woodgrain Painting

House Painting Sydney

Most internal wall painting is concerned with providing smooth even surfaces. Walls usually do not have patterns, they have pleasing background colours to set the right mood. Any details are usually provided with paintings, decorations and furniture. Yet occasionally we might want a pattern on a wall or painted surface.

Woodgrain is an interesting pattern, one that is never quite the same twice. Like fingerprints no two woodgrains are the same. This is part of the appeal.

Our aesthetic sense likes order. We like colours that match or that are complementary, we like neat proportions. But if we get completely plain colours with perfect proportions we risk getting a sterile result. It seems sterile because our brains tune out anything that is too regular, too plain. We want to see order made out of chaos, not order in isolation.

We might like to apply a woodgrain finish to a painted surface. This works well in moderation. A book shelf, desk or cabinet with a woodgrain finish can look quite stylish, especially in a plain surrounding, or with matching accessories. A door and frame or inbuilt amenities will also look good with woodgrain. But a whole room of woodgrain walls will feel too imposing.

Woodgrain House Painting Sydney

A graining tool can be used to give a woodgrain finish to a paintjob. Basically this is like a paint-roller with a textured rubber surface. By dragging his across a correctly prepared surface we can achieve a realistic looking grain effect.

The surface should be painted a dark colour, which is allowed to completely dry. This surface is then painted a lighter version of the same colour, and the graining tool is used to create a woodgrain pattern across the surface while the paint is still damp. Rocking the graining tool back and forth will create semi-random gain patterns that look realistic.

Office Painters Sydney

Consider some woodgrain painting for a more prestige look on cabinets, furnishings or other parts of a stylish office.

Hot Weather House Painting Sydney

Exterior House painting requires reasonable conditions in order to get the best results. Nobody paints while it is raining, and professional painters will often avoid painting in extreme heat or direct summer sunlight as the end results will be compromised.

Paint is designed to cure at a moderate rate in order to get a quality finish. If the paint was to dry too rapidly, perhaps because of extreme heat, it would compromise both the look and durability of the finished paintjob. It is a terrible waste when recent paintwork peels, flakes or just looks less than optimal.

Temperatures of 30 degrees Celsius or below are never an issue. It is only when paint is applied in environment above 33 degree that problems might occur. Of course this varies with the type and brand of paint.

  • Check the instructions on the paint. Some paint will work well in hotter conditions, and the manufacturer may specify this.
  • Painting in the cooler part of the early morning or afternoon can work well. Afternoon painting can dry overnight. Morning painting should be mostly dry before any midday heat.
  • Use the hotter part of the day for preparation rather than actual painting. The cooler weather is an advantage when we want recently washed walls to dry. Else, surfaces may be sanded.
  • Keep in mind that the house walls, especially those in direct Sunlight, may be hot even as the temperature drops. Wait for surfaces to cool.
  • Often there will be one wall in the shade, and this can be painted in moderate temperature conditions.
  • Removable items, like window shutters, can be taken elsewhere and painted.
  • Often the only option is to wait for more moderate weather.

Surface Stains

House Painters Sydney

Surface preparation is an important factor in painting walls or any surface. Walls being painted for the first time will be prepared with a suitable primer, which works well if the surfaces are sufficiently clean. Walls being repainted must be cleaned to remove years worth of accumulated grime, grease and oil.

Paint will not bond very well to a wall if there is any grime, grease or contamination. Even oil from human skin contacts can cause issues. Painting under these circumstances will result in blistering, paint that peels away, discolouration or just an uneven looking paint job.

Cleaning before House Painting Sydney

It is standard practice to clean walls with sugar soap or Trisodium Phosphate. These are mildly alkaline (base) solutions that remove most grease and oil from the surface of walls. Often this is sufficient preparation for re-painting walls.

Problem House Painting Sydney

Walls near cooking surfaces or fireplaces often need very heavy duty cleaning to remove grease or other contaminants from the walls. Bathrooms, which have soap scum in the atmosphere, and children’s rooms with crayons marks and hand prints may also require thorough cleaning.

  • Citrus cleaners like De-Solv-It are very effective for cleaning sticky spaces and removing grease. This is inexpensive and available at hardware stores. It is also quite safe.
  • Hand sanitizer will remove many visible wall marks. This is readily in most homes and worth trying
  • Acetone is a very strong solvent, and quite volatile, but it will work for very stubborn grease. It should only be used in a ventilated area. (It is the basis for nail polish remover).
  • Turpentine is the solvent in many non-water based paints. It will remove many grease stains. It is rather strong smelling and flammable, so use in a ventilated area.

Sections for doors, doorframes and windowsills that receive a lot of human contact will tend to accumulate a lot of skin oil, which prevents paint form bonding well. They may need to be cleaned with strong solvents.

Strata Painting Sydney

With many things the difficulty is in the detail. One of the difficult details in painting is the corners. Both convex and concave corners require a little skill if they are to be painted satisfactorily.

House Painting Sydney

Concave corners exist in every room. The edge where an internal wall meets the ceiling is one example of a concave corners. Most of the other walls in a room meet in this same fashion, usually a 90 degree angle.

A concave corner cannot be reached with a paint roller. Instead, these corner edges are usually painted with a small to medium brush. If the paint does not show any difference in texture between the roller section and the brush section, if there are no visible brush-marks, then the results can look quite good. Problems can occur if the roller paint is deliberately textured. It is hard to reproduce this texture with a brush.

A convex corner is the opposite type of edge to a concave corner. Think of the outside edges of a box – these are convex corners.

Convex corners will usually occur in a few parts of a house or office. They are common on cupboards, stalls and around stairways. The only issue they might present is a sharp edge. If this edge of a convex corner is too sharp the paint will not bond well. It will tend to either not stay on the thin edge surface or be prone to latter rubbing off. The best way to deal with this is to have rounded corners. The internal plaster or woodwork in a house should already have rounded edges. Else, edges can be rounded with a sanding block or routing tool.

Strata Painting Sydney

It is easier to paint a building before the ceiling edges and cornicing’s are installed. If these fixtures are put on after the walls are painted they cover all the joints at the ceiling and floor.

Owners of apartment and strata complexes should arrange for painting before the building has its final cornicing installed. This both makes the painting easier and allows for a few more painting options.

Office Painters Sydney

Neat office surroundings are expected in any business. Neat surroundings both reflect the attitude of your company, and help give the employees some sense of solidarity and group morale.

Offices are usually neat, functional and tidy rather than fancy. But is helps to organize a good paint scheme when planning and building an office.

House Painting Sydney

Bathroom House Painting Sydney

Bathroom painting is a different to painting other rooms in the house.  Bathrooms will contain moisture both in the air and on the floor. This inevitably has an effect on the walls and paintwork.

Where most internal rooms use matt or eggshell paint the bathroom will more often use gloss finish paint. This is because the gloss finish will resist moisture and staining far better than any other paint. The water, soap and occasional grease that a bathroom is exposed to will generally be easy to clean off glossy walls. The same moisture, soap and grease would stain walls with matt paint.

The downside of glossy paint is that it is poor at hiding surface imperfections. The glossy sheen reflects light, highlighting any unevenness in the walls. When painting bathrooms the walls must be very carefully prepared.

Ask House Painters Sydney

Bathrooms walls will use a combination of tiles and painted surfaces. As the home is redecorated over time one of both of these will change. Of course it is a much easier task to change the paint than it is to change the tiles. So new paint should be chosen to match the tile décor. Else, either the tiles or paint can be a fairly neutral colour that suits any décor.

White tiles and porcelain are a versatile option. Almost any colour will go with this white décor. Dark glossy paint provides a good contrast with white tile trim. Else, light pascal colours look very peaceful with white.

A bathroom with more elaborate stone or faux wood tiles works better with light and neutral coloured paintwork. The paint should not dominate the look of the tiles.

Light and House Painting Sydney

Bathrooms can often have various different forms of lighting. Skylight, faux candlelight, or conventional lighting will all change the look of the room. Consider this when choosing a colour scheme.

Precautions and House Painting Sydney

Paints are synthetic and contain chemicals. Some of these chemicals are released into the air as the paint dries. Modern paints contain and release less chemical smell than paints of a few generations ago, but the small amount of chemical vapour released is best avoided.

The smell of fresh paint is due to the release of VOCs, Volatile Organic Chemicals. The best known of these chemicals is formaldehyde. Formaldehyde is present in small amounts in many manufactured goods, from clothes and furniture to carpets and car interiors.  It a health risk and tends to aggravate allergies, especially with breathing or eyesight. It is best to wait for this chemical smell to dissipate before habiting a room.

To help detox a Room after it has been painted, or recently re-carpeted.

  • Open windows and doors to ventilate the room. Use some fans.
  • Air filters or air purifiers, especially with HEPA filters, will clean the air quite quickly. It is a good idea to use these on a regular basis.
  • Cover the floor with Bicarbonate of Soda, which absorbs a lot of chemical smells. This is especially good on new carpet, but it helps with paint to a small degree.
  • Open containers of water with sliced lemon will soak up a lot of chemical smell. Some people also add some salt.  Leave the container of water / lemon around the room for several days after painting, then dispose of them.
  • Sliced onion also soak up chemical smells.
  • Bicarbonate of Soda absorbs a lot of chemical smells. This is especially good on new carpet.
  • Charcoal will absorbs odours, though it is a nightmare to clean up if it spills.
  • Keeping some indoor plants around will help clean the air. This is a good long term practice. Search the net for the plants most effective for cleaning air. The only disadvantage is that indoor plants will raise the humidity slightly.

Newborn children and pregnant women should never be exposed to paint or recently painted rooms. Some paint chemicals are linked to birth defects.

Question For house painters Sydney

How long should I wait before using a recently painted room?

Modern paints are much better in this regard than older types of paint – there is less chemical smell and much less chemical residue in the air. Nonetheless we recommend airing out the room with open windows and fan, and waiting several days before sleeping in the area.

Young children and pregnant women should be kept completely away from recent paintwork. Wait at least a week.

Can exterior paint be used indoors?

It could be, but there is usually no reason. Exterior paint tends to be more expensive, and offers no real advantage. It also takes longer for the chemical smell to dispel. Occasionally some left over external paint is used for internal windowsills or doorframes, but only to use up the excess. There is a small advantage in that external paint on a windowsill will resists fading in the Sun.

Will Glossy paint make a Room more Hot?

This appears to be an internet rumour. External paint type will effect the humidity (rather than heat) of a house, but internal paint finish isn’t going to make much different to the heat or moisture.

Are there any problems in painting over Gloss of Matt finishes?

Matt paint is reasonably easy to paint over, as long as the surface is well cleaned with sugar soap. Unfortunately Gloss paint is difficult to paint over; the new layer of paint will not stick well. The old layer of gloss paint will have to be roughened before the paint can bond properly. Latex paint gives similar problems.

Why Use Gloss Paint?

Gloss paint has traditionally been easier to clean and resisted moisture, so was used in kitchens and bathrooms. But new eggshell paint rivals gloss paint for easy cleaning, so it is mostly a personal preference. Gloss finish paint will tend to show any imperfections.

Should the Ceiling Be Painted First?

Painting the ceiling will prevent any spillage upon the recently painted walls. Otherwise it make no difference. Professionals have few, if any, problems with spillage.
