How is Antirock Primer applied?

Brush, roller or spray onto a clean, dry, dust-free substrate. Shake well before use. Allow to dry fully before applying torch-on membrane — never accelerate drying with a torch.

Which substrates does it suit?

Designed for concrete and metal substrates being prepared for Soprema bituminous torch-on membranes. Not for self-adhesive membranes — use Elastocol Stick for those.

What is the coverage rate?

0.15 to 0.25 L/m² depending on substrate porosity. One 19 L pail covers approximately 76-126 m².

How long before I can torch over it?

Drying time varies with temperature and humidity. Wait until completely dry to touch with no solvent smell — typically 30 minutes to several hours.

What are the safety requirements?

Highly flammable (Class 3, UN 1263). Store away from direct sunlight and open flame. Keep all ignition sources away during application and drying.

Why use a primer at all?

Improves bond strength of the torch-on membrane to the substrate, particularly on dusty or porous concrete. Skipping the primer is the most common cause of delamination.
