There are many ways of applying paint or other coatings to a surface. Thorough preparation of any surface to be coated is imperative to achieve a quality final finish.
Painting preparation usually follows these steps;
Clean or wash down the surface to be painted to remove all contaminants.
Remove all loose or poorly adheard old coatings.
Sand or abrade to promote adhesion for the new coatings and to improve the existing surface if required.
Fill any cracks, blemishes or holes.
Remove and clean up any debris and dust from painting preparation works before commencing painting.
Mask out any areas that are not to be painted and cover all areas not being painted with drop sheets.
The most common method of applying paint and other coatings in most cases is by using a paint brush. Load the brush with the coating then use the brush to spread the paint evenly onto the surface to achieve a consistent film build.
If broader areas are involved time to apply the coating can often be reduced by using a paint pad or paint roller, or even by spraying the coating onto the surface with spray painting equipment or a power roller.
Painting takes time, dont try to rush the job. Apply each coat as evenly as possible and avoid runs by not trying to apply too much at once. A better finish will usually be acheived by applying 2 or more even coats than trying to acheive coverage with one coat.
Check with the coatings manufacturer and follow the recommendations for any prepatory coatings such as primers and undercoats, allow the specified times between applying coats and apply the recommended number of coats at the specified thickness to ensure a quality finish is achieved and the coatings manufacturers waranties will not be voided.
