sealers
Why seal?
Building materials such as natural stone, tile, masonry, concrete and grout are all made up of countless invisible capillary pores. This makes them porous and allows the absorption of damaging liquids such as water, water-borne salts and oils. These liquids cause the building material to deteriorate prematurely and in so doing reduce their usefulness. Examples of deterioration include; weathering, loss of strength, efflorescence, salt attack, freeze-thaw spalling, sulphate attack, alkali aggregrate reaction, unsightly staining, biological attack, reinforcement rusting, chemical attack and picture framing. Sealing can eliminate or significantly reduce most of these problems.
What type of sealer should I use?
There are two main types of sealers, namely, surface sealers and impregnating sealers. A surface sealer will provide a physical barrier over the surface. The result is a darkening of the surface. These coatings usually wear and weather relatively quickly, make the surface more slippery when wet and must be completely stripped off when re-coating. Salts may also build-up under the surface, causing the coating to appear cloudy. Impregnating sealers can be classified as those that repel water and those that repel both water and oil based stains. Impregnating sealers usually have little effect on the frictional properties and appearance of the surface but will not completely stop dirt and rubber getting into the open pores of the surface. When comparing similar sounding impregnating sealers the two most important questions are: (a) is it permanent? and (b) how deep does it penetrate below the surface? A good depth of penetration is critical to provide protection against traffic wear and weathering.
How do I calculate the amount of sealer required?
To determine how much sealer you'll need, measure the length and width of the area to be sealed. The amount of sealer used will depend on the particular material being sealed. For example, to seal a wet-poured cement-based paver you will need 1 litre per 7 sq.m. (1 quart per 70 sq.ft. per quart) and for sandstone you will need 1 litre per 4 sq.m. (1 quart per 40 sq.ft. per quart). Your Dealer will be able to provide a guide to the amount of sealer needed for a particular material being sealed.
