Ronseal Superflexible Primer & Undercoat White 750ml

The Ronseal Superflexible Primer & Undercoat is a high-quality, highly flexible wood primer and undercoat designed to improve the performance of your exterior topcoat finish. Its special flexible resin allows it to move with the wood, maintaining adhesion and helping to prevent cracking and peeling of the topcoat. It adheres superbly and serves as both a primer and undercoat in one, providing the ultimate base coat for any topcoat.

This product features an advanced stain-locking mechanism that prevents extractives and tannins found in resinous woods like Mahogany, Oak, and Teak from discolouring your paintwork. It is ideal for priming any exterior hardwood and is also suitable for interior wood applications. The white primer is excellent for lighter-coloured topcoats, while the grey variant (available separately) works best for darker colours.
