Ever run your hand along an old wall and come away with a chalky, powdery residue? That's a wall that won't hold paint. Fresh coats will keep flaking, peeling and letting you down, no matter how good the paint on top is. Gush DeepSeal fixes the problem at the root.

This water-based penetrating sealer soaks deep into tired, powdery and crumbly walls, binding the loose particles together and turning an unstable surface into a solid, paint-ready base. It's the difference between a paint job that looks great for a month and one that lasts for years. And because DeepSeal works as both a surface treatment and a sealer in one, you're doing two jobs with a single tin, saving yourself time, effort and the cost of an extra product.

Best of all, it's kind to your home. Ultra-low odour and formaldehyde-free, so there are no harsh fumes lingering in your rooms, it goes on easily with a roller, brush or spray, dries in around four hours and cleans up with nothing more than water. Prep your walls properly with DeepSeal, and the finish you fall in love with is the one that stays.
