The Acratex Green Render Sealer 15LT is a water‑based primer and sealer designed to prepare fresh masonry surfaces such as new concrete and render for subsequent coatings. It forms a penetrating barrier that helps to minimise efflorescence (white salt deposits) migrating through your coating system. Then you can paint sooner and more confidently than with untreated surfaces.
This render sealer helps fast‑track your project schedule by reducing the typical waiting period on new concrete or render. In many cases, you can apply coatings after just two days once moisture has stabilised. Because it seals and primes in one step, you also get better adhesion, improved durability and fewer problems with dirt or moisture pickup before finishing coats.
Key Features
Water‑based primer/sealer: Easy to apply and cleans up with water.
Reduces waiting time: Helps you paint over fresh render sooner than standard cure periods.
Seals porous masonry: Creates a barrier against moisture and dirt pick‑up.
Minimises efflorescence: Reduces white salt migration through coatings.
Improves coating adhesion: Helps subsequent topcoats bond more consistently.
Applications
Priming newly rendered or concrete surfaces before painting.
Exterior walls and masonry where accelerated schedule matters.
Projects that need reliable adhesion and fewer substrate issues.
Preparatory sealing for texture, acrylic or protective finishes.
This render sealer is ideal for painters, contractors and renovators who want better adhesion, quicker turnaround and a more durable coating system on fresh masonry.
