Description

So much more than a damp sealant paint…Hydroblock impregnates and actively rebuilds the original colour and look of your walls and paving slabs.

If you’re looking for brick waterproofing as well as a breathable brick sealer then Hydroblock is the masonry sealer for you.

A significant step up from a simple brick sealer, and as easy to apply. HydroBlock is at the front of the latest trend in coatings –  impregnations –  which have the unique ability to provide invisible penetrating damp protection after a simple application. We believe HydroBlock has the longevity and reliability to outdo other brick sealants. Invisible protection that penetrates deep below the surface to give effective and long lasting masonry weatherproofing, as well as keeping substrates bright, clean and dry.

Hydroblock Solvent Based and Hydroblock Water Based are unique products for the maintenance and waterproofing of roof tiles, surfaces of limestone, concrete, bricks and many others. HydroBlock Solvent Based is more penetrating than the HydroBlock Water Based so is ideal for harder surfaces such as granite.

It can be used on facades, floors, concrete and clay, paving stones, bricks, sand-lime bricks, mortar, sandstone, granite, and mineral plaster/render. You can even use it as a chimney brick sealer.

Not just a simple brick sealant or damp sealant paint, Hydroblock penetrates the surface and builds up a chemical bond to the material enhancing and protecting it by making it dirt and water resistance. It actively rebuilds your surface’s original colour and look, and protects it from frost damage and penetrating damp for up to ten years.

Why Choose Hydroblock?

Why Choose Hydroblock?

This is an invisible treatment that goes beyond just brick waterproofing. Using the latest technology, HydroBlock penetrates deep within the substrate and chemically bonds with the material, turning it hydrophobic.

  • Treat penetrating damp with a single breathable treatment
  • Prevent frost damage from cracking masonry by keeping walls dry
  • Invisible protection that enhances the current look and style
  • Self cleaning, meaning surfaces use the rain to clean themselves
  • Masonry stays brighter and healthier for longer
  • Prevents growth of moss, algae, and lichens
  • High coverage rate of 5m² per L
