Like all natural stone products, cast stonework and concrete products should be regularly maintained of your wishes in order to keep them in good condition.

The frequency of cleaning will depend wholly on the location and amount of use that the surface gets.

Domestic installations will have less use than those in commercial, educational or urban areas. Therefore maintenance requirements will vary accordingly.

Urban areas are more prone to higher levels of pollutants such as oil, chewing gum, and cigarettes. All of these can be difficult to remove on any hard surface.

Whatever the location, cleaning is assisted by the actions of wind and rain.

Blanc de Bierges are pleased to be able to offer to its customers a range of cleaning and maintenance products designed specifically for use with cast stonework and Blanc de Bierges products.

Along with the supply of products we are also able to offer an application service giving our customers the total peace of mind that their stonework is being protected for many years to come and will keep the stone looking as good as new.

Dry-Treat™ develops world leading impregnating sealers & enhancers for natural stone, bricks, pavers, tiles, engineering concrete & grout AND Hanafinn™ safe, environmentally responsible specialty cleaners.

The special penetrating sealer molecules are hundreds of times smaller than competitor stone sealers and penetrate much deeper into the pore structure, even dense natural stones like granite. Inside the pores our special sealing molecules bond permanently by chemical reactions , creating a substantial, deep oil and water-repellent barrier.

The deeper Dry-Treat barrier, not only provides great surface stain protection, but also protection against more serious common types of damage cause by water ingress (penetration), including efflorescence, salt spalling, freeze-thaw spalling, and picture framing.
