More than a mere brick sealant. HydroBlock penetrates deep into the surface and so provides long term protection. After a simple application your walls are safe from penetrating damp and frost damage. No more ugly cracks caused by rain penetration and freezing.

On top of that, your property appears brighter, cleaner and healthier. Self-cleaning walls mean dirt and grime won’t build up as easily, and rainwater is used to wash the surface rather than damage it. Less cleaning from you, and you still get brighter walls.

Damp wall treatment and better energy efficiency

Waterproofing gives you numerous benefits. A dry healthy wall keeps heat where it’s meant to be, reducing your energy bills.

A wet wall can release twice as much heat as a dry one. By keeping your walls dry, HydroBlock lowers the thermal conductivity of your walls, meaning heat stays where you want it to, and you save money on your energy bills. As a breathable treatment, HydroBlock allows harmless amounts of moisture to escape while preventing excess rain from getting in.

From the sealant experts, ISO Paint

Got marble or granite surfaces? You can get HydroBlock as a solvent based version for use on hard minerals.

HydroBlock is based on the latest nano-technology. Here’s the science: A chemical composition of siloxanes with free reactive groups enables HydroBlock to actively bond to mineral surfaces such as concrete, brick and stone and protects against rain, dirt, algae, pollution, oil and others. That’s how it’s so much more effective than the average brick sealant.
