As we all know a new coat of paint can transform spaces within hours and have the most dramatic lasting affect at the lowest price as compared to other trades. Many people tend to think painting is as easy as lifting the paint brush and couple of strokes, Job done! But real professional decorators know very well that there are a few steps that you have to follow in order to achieve a durable and attractive finish before you even open the paint can lid.
The subject we will be dealing with in this post is Primers and how they affect your over all top coat feel and visual look. You can think of primers like the foundation on which your building stands, we all know a solid foundation is a key to any thing specially when expecting your finish to last for years to come. The surfaces of all objects, building and walls have a surface which is very porous meaning there are small gaps on the surfaces of bare materials that sometimes you can see and other times you cannot, these pores absorb paint soaking in the colour pigment and paint itself causing imperfections in the paint and also sometimes adhering problems which are the highest cause for paint peeling.
A primer seals the pores on a surface and specialist primers can be purchased for nearly all materials known to man, another reason why you should always prime bare surfaces before applying any paint. Primers are thicker than your usual wall paints as this allows them cover pores better rather than sinking in to any small imperfections like normal emulsion would, normally one coat of good quality primer if enough to fully seal any material prior to paint application which can be followed by two coats of undercoats and one coat of top coat completing the paint seal.
You can think of primers as Problem Solvers, as previously addressed if you are not happy with your top coats chances are it’s your priming to blame not the paint its self. No bare surface if perfect and ready to paint unless it has been primed.
Another thing Primers do very well is get the surface ready to hold the paint when application starts as primers are designed to be a great base to cling on to paint which without its use would not adhere as well resulting in faded patches within the finish as well as risk of peeling.
If done correctly using the right type of primer for your surface can dramatically increase job turn over time and provided added durability to the finish with long lasting results, some of the benefits of using a Primer before painting are;
They reduce amount of surface preparation required doing some of the work on behalf of the decorator sealing imperfections on the wall.
A Primer can double the adherence of your paint and therefore double the speed of your coats as a perfect base if set up for even colour pigment pick up and spread.
Long lasting finish is another great reason to use a primer when you decorate is that it creates a perfect base for your paint to adhere to allowing a quality seal which will never tear meaning your painted surface will never chip or peel with time.
The primary functions of a Primer is to Seal the pores of a surface as well as creating a key base coat foundation for the paint to adhere on, but there are some specialist primers which are made to cover stains on walls and other materials where the paint is not thick enough or does not have enough pigment to seal the stain.
