stone

Various stone varieties such as marble, travertine, sandstone, limestone, granite, terracotta, slate, bluestone/basalt, concrete, pavers, tiles, concrete render and masonry surfaces are all susceptible to moisture damage leading to the corrosion of steel reinforcement, etching, growth of algae and moss on exterior surfaces.

Shellkote provides a service to clean and seal your stone/paver assets using only the most advanced sealers available on the market and are licensed to apply and pass on the manufacturers guarantees to you.

We specialise in cleaning and sealing both new stone/paver installations as well as bringing new life to old works.

The first step in any stone/paver sealing project is to clean the surface of any stains, dirt, or debris that may be present. Any efflorescence, grease from BBQ’s and the like, oil spills, or other heavy deep set stains are chemically treated during the cleaning process. A variety of specialised degreasers, detergents and efflorescence removers are used as necessarily required.

Once clean, our technicians will liaise with you to select the perfect sealer that suits your individual requirements. Our sealers will not alter the surface texture or make surfaces slippery and will facilitate an easy to clean, self-cleaning process on treated surfaces. Our sealers will enhance the appearance of your property and will protect your investment for years to come.

Is efflorescence a problem for you?

Efflorescence is the migration of a salt to the surface of a porous material, where it forms a coating. The essential process comprises the dissolving of an internally held salt in water, or occasionally in another solvent. The water, with the salt now held in solution, migrates to the surface, then evaporates, leaving a coating of the salt.

Efflorescence can occur in natural and built environments. On porous construction materials it may present a cosmetic outer problem only (primary efflorescence causing staining), but can sometimes indicate internal structural weakness (migration/degradation of component materials).

You must seal the surface with a high performance sealer as soon as is practical after the building material is installed. The sealer must be deeply penetrating, able to withstand the highly alkaline environment found in cement based-materials and be completely breathable so moisture cannot be trapped below the surface.

Once the surface is sealed a deep water-repelling layer is formed. This layer will prevent water and dissolved lime compounds from reaching the surface where efflorescence could occur. At the same time the sealer stops further water soaking into the surface and so breaks the cycle of efflorescence. The unused lime compounds are left harmlessly immobile in the core of the building material with little contact with carbon dioxide. Since the sealer can breathe, sub-surface moisture can escape as water vapour rather than in a liquid form.

Good news! We are able to treat your surface to get rid of your unsightly efflorescence problem.
