Undercoat vs Primer: What’s the Difference and Do You Need Both? Surrey Painters
Hardwoods also benefit from primer as their natural grain can result in an uneven paint job that can break down faster. Plaster is very porous and will require primer for the best results. When choosing a primer, start by considering the type of material you are painting. Surfaces like bare wood or new plaster will need 2 coats of primer. It all depends on the surface and the type of transformation.
Thank you for reading this post, don't forget to subscribe!There are some primers designed to work with different materials at once. If you’re working with peeling wallpaper or fabric-based wallpaper, it’s best not to paint over it. Allow 24 hours for the primer to cure and completely dry before applying your topcoat to ensure effectiveness. If the old paint is in good condition, there is no need to prime it, and an undercoat will still provide a smoother finish before applying the topcoat.
Tikkurila have created a full range Koko.nl verfwinkel of primer shades designed to help achieve maximum opacity of the topcoat. When choosing the primer shade, the best result can be achieved when the primer shade is from the same colour family. Using a coloured primer will neutralise the colour of an existing surface helping to achieve the desired result with fewer coats. Primers are designed according to whichever surface type they are intended for. If you are making a drastic colour change, for example from a dark to a light colour, the primer has properties that will help mask the colour beneath before applying the topcoat.
Recognising the Value of Undercoat Paint
- They ensure strong adhesion between the surface and later paint layers.
- Plaster is very porous and will require primer for the best results.
- It ensures adhesion and prevents future peeling.
- An undercoat builds smoothness and provides a solid, uniform colour base for your topcoats.
- The surface is then able to be receptive to subsequent layers.
- Primer paint contains special adhesives to stick to their designed surface and to create a smooth surface for the topcoat.
- That depends on the surface in front of you, not the label you’d prefer to buy.

They show up later, when paint that looked perfect on day one starts to flake, flash or bleed, and the only real fix is stripping back to start again. Base coats are more sensitive to conditions than most people expect, and the times on the tin assume a warm, dry room. Both primers and undercoats come in water-based and oil-based versions, and the trade has swung heavily towards water-based since the VOC regulations changed the chemistry of solvent paints. Because this trips so many people up, we wrote a separate guide on how to paint over gloss that covers de-glossing, priming and getting a lasting bond.
