Superb undrcoat

This is another paint that is highly recommended by my decorator. It has great adhesion, coverage and consistency. A superb quick drying undercoat to complement the top coat.

This product was great

I bought this product and it was great it done a good job

DIY Jim - 5 / 5 - 18/05/2026

Did the job required without issue

Bought this product as the previous paint came away from a wall which had been wallpapered and returned the wall to bare plaster. I was a little concerned with some reviews that stated the paint dripped a lot but I had no issue applying the paint with a roller and also using a brush around the edges. The product was very nice to use, dried quickly and looked fine after 1 coat but I applied a second coat the next day. When I then applied the main paint bought for the room, you wouldn’t know that one wall had a different product on it.

Top stuff- it's not a final coat! (poor reviewers)

It’s a primer undercoat. Just to reiterate what another reviewer has said, this paint is a primer undercoat. It’s function is not to act like a top coat and hide what is underneath. It’s is to provide a good bond to the surface underneath so that the top coat does not peel off. I have used it on several projects and it does this well.

Its actually pretty good

I bought this when repainting my kitchen cabinets. First I want to clarify, this is not a paint. It is a primer. Other reviews seem to think it's going to give perfect coverage, its not. It will however coat your surface well before painting. I removed the vinyl covers from my cabinets, and then sanded well, and cleaned any residue from them before using this. I found it easy to apply, quick dying and not too smelly. If you slap it on without sanding or cleaning the area first, you arent going to get a good finish. Read the instructions and it's good. I followed up with valspar paint and 7 months later its holding up great. I bought another tin last week and I'm now using it to do my mums kitchen too. Long story shirt, it's pretty good if you use it right.
