How to Apply White Primer Paint For Walls?

Step 1 - Apply the first coat of white primer for walls to a smooth, absorbent surface to create a well-prepared base. Allow it to dry fully, then lightly sand to get an even finish.

Step 2 - Apply a second coat and sand again if required. For new plaster or bare wood, additional coats may be needed to ensure a smooth surface before applying whiteboard paint or other coatings.

FAQ's

No, primer and undercoat are not the same. Primer is used primarily to seal surfaces, improve adhesion, and block stains, while an undercoat builds colour depth and smoothness before the final paint coat.

Primer always comes first. It prepares and seals the surface for proper adhesion. An undercoat, if needed, is applied after the primer and before the final paint finish.

White primer paint is used to create a smooth, sealed base that improves paint adhesion, blocks stains, and evens out surface colour before applying top coats or speciality paints.

Painting without primer can lead to poor adhesion, uneven colour, increased paint absorption, and reduced durability, especially on new, porous, or strongly coloured surfaces.
The best white primer paint for walls is actually your secret weapon for better adhesion of performance top coats. It not only boosts the durability of the final finish but also prepares the surface perfectly for speciality coatings.
The number of coats depends on the material and condition of the surface. In general, two coats should help attain a smooth, non-absorbent base. However, for tricky surfaces like new wood or plaster, you might need a few extra coats, along with sanding, to get a beautifully smooth finish, especially when prepping for something like whiteboard or magnetic paint.
Allow White Primer to dry fully before applying your top coat. This usually takes a few hours, though it can vary depending on the temperature and humidity in the room. However, if you are in a rush, then introducing a bit of heat can speed up the drying process.
Absolutely yes. Sanding after the primer coat ensures you have achieved a nice, smooth surface ready for the final finish. This is especially crucial when applying specialty coatings like whiteboard paint.
White Primer is extremely versatile. It works wonders on a wide variety of surfaces such as wood, plaster, glass, drywall and other similar absorbent materials or surfaces with low surface tension. So if it’s a surface that needs prepping, this primer has certainly got you covered.
For achieving the best results, particularly when preparing surfaces for specialty coatings like whiteboard or magnetic finishes, a high-quality foam or mohair roller is your best bet. However, for larger areas, make sure to opt for bigger rollers. If you go for a mohair roller, just ensure to remove any loose fibres before you begin. It will ensure a flawless finish every time.
