Sandtex Exterior Primer Undercoat gives exterior wood, metal, and masonry a tough, flexible base coat. It is part of the Sandtex 10 Year range, built to resist cracking and flaking outdoors.

This 750ml tin is a multi-surface formula. First, it primes. Then, it undercoats. As a result, you get one product instead of two, which saves you time and effort on exterior prep work. Better still, it comes in two shades, so you can match it to your finish coat before you even start painting.
