Primer House Painter Sydney

Professional Painters Sydney

Paint is very rarely applied directly to a surface.  Most surfaces need a primer coat in order for the paint to bond well. Different surfaces, wood, plaster, metal …etc. usually require different primers.

Interior Residential House Painting Sydney

Most interior walls surfaces are Gyprock (plasterboard). This gyprock surface cannot be painted on without first applying primer. Without primer the paint soaks into the gyprock panels, giving a terrible result. And the plaster joints between the gyprock panels sow through the surface. 

Primer gives Gyprock walls a neutral looking surface that bonds well to the final paint. The even texture from this primer prevents the joints in the wall from showing through.

Metal Primer

Metal is often tricky to paint as many chemical will not bind to the surface. This is especially true of aluminium. Primers for metal will etch into the metal surface, providing a slightly rough texture that bond with paint. These primers often have reasonably good rust proofing qualities.

Wood Primer

A different type of primer is used for wood. This primer will both fill in the grain of the wood and prevent the final paint from soaking in.

The paint used on gyprock can be used on wood if both surfaces have the right primer. But it is more common to paint woodwork a different colour or to stain the surface.

Some wood paints are designed show the grain of the wood through the final finish, and are to be used without primer. These are uncommon.

Masonry Primer

Masonry work like pipes will require masonry primer that will bond to the smooth surface.

What about paint with built in primer?

These do exist, but for several reasons they have never proved popular. For one thing they are rather pricy. It is cheaper to buy an ordinary primer and a good quality paint. Another problem is that these paints often need two coats, which takes the same amount of time as a primer with a topcoat. Finally, the paints with built in primer are not available in all colours and finishes, so you may not find the colour that you want.

Good quality paint over a decent primer offers a lot of décor possibilities.

Surface Preparation before re-Painting

Painting Service Sydney

Correct preparation is an essential part of any craft or trade. Walls, ceilings and other surfaces needed to properly cleaned as part of the preparation for re-painting.

A new house of new room will use an appropriate primer before painting. Re-painting does not require primer, but it does require cleaning. Failure to correctly clean the walls and ceiling will lead to a disappointing paint result.

Residential House Painting Sydney

Residential homes and other building will accumulate grease, dirt, grime, dust and other contaminants on their surfaces. These contaminant will prevent a layer of paint from correctly bonding to the surface. Even the grease from human hands is enough to cause problems with re-painting.

Attempts to paint over an unclean surface will lead to painted walls with a rough surface, blistering or peeling paint, paint that quickly flakes away from the wall, or simply walls with uneven colour. This is unsatisfactory.

It takes as much time to paint a clean surface as it takes to paint a badly prepared surface. But the badly prepared surface will look far worse. It then takes more time to fix the problems with the paintwork. It is better to prepare the surface correctly; this saves time later on.

Cleaning for Professional Painters Sydney

It is best to clean walls with sugar soap or Trisodium Phosphate before painting. These are mildly base (alkaline) solutions that remove almost all grease and oil from any surfaces. Usually this type of cleaning is sufficient for most rooms of the house.

Walls nears stoves or fireplaces may require more heavy duty cleaning. The grease and other contaminants on these walls have been baked on with high temperatures, and are often a little difficult to remove.

Citrus cleaners like De-Solve-It will remove most heavy grease problems. These are quite safe.

Turpentine and Acetone are very strong solvents that can be used for extreme stains and stubborn grease marks. Care must be taken as these solvents are harmful to skin and quite flammable.

Bathrooms tend to accumulate soap scum, so they need thorough cleaning. Any areas that are frequently touched by hands, like cupboard handles, of window sills and frames, probably need extra cleaning attention.

Types of Paint Finish

Interior Painting Services Sydney

House paint comes in countless different colours, and it also comes with several different finishes. The finish is the surface texture and shine of the paint, factors which affect the light reflecting properties of paint on a wall. Each of the different finishes have a few advantages, though with modern paint these advantages are less pronounced than in the past.

Gloss Paint

This gloss paint was one the most common type of paint both indoors and out. It has a smooth, almost mirror type finish that is easy to clean. It is also quite water resistant. Its only disadvantage is that its light reflecting properties will show any imperfections on the surface. So walls must be free from dents and scratches before painting.

These days Gloss paint is mostly used on external houses painting. Internal painting often uses other paint finishes.

Semi-Gloss

This is a less shiny version of Gloss paint. It is reasonably easy to clean and will not reveal wall imperfections. For many years this was popular for indoor painting, being seen as a good compromise between gloss and matt finish.

Matt Finish Paint.

Matt paint has a less reflective surface, almost like chalk. This means it effectively covers up imperfections in the wall. But it also tend to be prone to staining as the textured surface was a hared to clean and prone to absorbing liquids and grease. Modern matt paints are significantly better for cleaning than matt paint from a generation ago.

Eggshell Paint Finish

This is a modern paint technology. Eggshell finish paint will hide surface imperfections in a similar manner to Matt paint, but it is also quite easy to clean and not prone to staining.

Eggshell paint combines the advantages of other paint types. It has proved the most popular internal paint in recent years.

Eggshell paint can be put on with almost any roller and brush. By contrast, a good gloss finish requires a fine bristle brush and a certain smooth finish roller nap (surface).

Eggshell finish and some modern matt finishes are the popular choice for most interior surfaces. The exception is bathrooms and some kitchen surfaces where the improved moisture resistant properties of gloss are preferred. Some people also like gloss on windowsill and skirting boards, simply for the shiny finish.
