Hydrobar Acrylic VHD Sealer (Vinachem) is an aqueous polymer solution containing ultra fine acrylic particles which allows maximum active penetration into concrete, masonry and brick. 

Penetrates deep into the masonry, coating the internal pores of the substrate, consolidating any friable material without blocking the pores of the masonry that are essential to allow the stonework to breathe.

Hydrobar Acrylic VHD Sealer (Vinachem) is a weak alkaline solution (pH 8-9), so it does not react with the cements and masonry.

Will protect concrete from carbonation by protecting the calcium hydroxide in the cement paste from reacting with the carbon dioxide in the atmosphere, thus reducing the amount of calcium carbonate formed and extending the life and durability of the concrete substrate.

Hydrobar Acrylic VHD Sealer (Vinachem) is hydrophobic and therefore will repel moisture. Water will either evaporate or run off without penetrating the masonry, it is non-toxic, non-flammable and UV resistant.

Has been applied to lighthouses and buildings in coastal areas where the environmental conditions have demanded a high performance solution.

Historic buildings and new build projects can all benefit from this colourless, non-staining, easily applied solution. Can be applied to concrete, stone, brick or any type of masonry. Re-application is generally not required for 5 years.

Easily applied and requires no specialist equipment or specialist training.

By applying one single coat only by brush, roller or low pressure sprayer to all surfaces requiring protection, normally, within 90 minutes, and will be touch dry and fully moisture repellant.
