It moves with the wood to maintain adhesion to help prevent cracking and peeling of the topcoat. It adheres superbly and both primes and undercoats in one, providing the ultimate base coat for any topcoat. It also has an advanced stain locking mechanism that creates a barrier stopping extractives and tannins found in resinous woods from discolouring your paintwork. Ideal for priming any exterior hardwood including Mahogany, Oak and Teak. Use on exterior wooden doors, window frames, cladding and fascia's. Also suitable for interior wood. White primer is great for lighter colours, whilst the grey primer is great for darker colours. Coverage: 10.0m² covered per litre. Number of coats: 2. Application: Brush. Drying time: 2 hours. Box Contains 1 x Super Flexible Wood Primer and Undercoat Grey 750 ml Review: A Must for external wood! - Really great product! This is the second tin I've bought of the Ronseal Primer and Undercoat. I repainted all the exterior wooden windows in my house, and before I started, they looked all weathered, uneven, minor cracks etc. A quick prep and two coats of the undercoat and they were really smooth and good for painting. It was touch dry pretty quickly (less than 30 mins) but i re-coated after 2 hours. I left overnight before applying the paint finish, but due to the surface being smooth and fresh, it only took one coat of brown paint to finish the windows. Review: it does what it says - I think where paint is concerned you get what you pay for. Ronseal produsts are always good and this undercoat went on easily. two coats and then the top coat of satin gloss looked fabulous./ ## Features - Contains benzisothiazolone.
