Rated 5 out of 5 by Tony from Works well on doors I was painting the front door to my flat which is an internal door. I emailed the technical team for their advice on whether I should choose the internal wood or external wood primer/undercoat for my door which I'd only been able to lightly sand and which had some old varnish not fully removed. To my surprise they suggested the wood floor primer & undercoat as it has good adhesive properties. It worked extremely well, left a flawless finish and provided the perfect base for the gloss paint that went on top. A 750ml tin comfortably provided 2 coats for my door with about 1/3 of the tin to spare.

Rated 4 out of 5 by Katherine from Essential for old floorboards We bought this product hoping that it would improve paint durability on our stairs and floorboards -- still too early to know about durability! If you have older floorboards, especially those that have not been painted before, I would recommend buying this product (buy more than you think you need) as we found our floors absorbed a lot of paint. I think it is quite useful having a midtones undercoat which is similar colour to the final coat (Lamp Room Gray midtone in our case) but not exactly the same so you can see where you've missed a spot.
