Sethard L
Lithium-silicate liquid surface hardener and dust proofer for concrete
Sethard L is a clear liquid surface hardener and dust proofer designed for application to concrete and other cementitious floors.
Sethard L is based on an aqueous solution of lithium silicate to enhance surface penetration. Sethard L will react chemically with concrete to produce clear, dense, durable and abrasion resistant surfaces.
- Single component, easy to apply.
- Significantly Improves abrasion resistance and hardness of the concrete surface.
- Improves the durability of concrete.
- Acts as a dust proofer, as it reacts with the salts in the concrete surfaces preventing the release of concrete dust through the pores on the surface.
- Concrete surfaces will remain breathable.
- Densification of the concrete surface, as it penetrates deep and reacts to fill the pores of the concrete.
- Contributes to the enhancement of the compressive strength of concrete at all ages.
- Increases water retention, which aids in the curing process of concrete.
- Ensures proper bonding of subsequent coatings to the concrete surface since it eliminates surface concrete salts and dust.
- Provides a clear finish that does not affect the natural look of the original masonry or concrete surface.
- Enhances the ease of cleaning and removing oils, greases and other surface contaminants.
- Controls hairline cracks in new concrete.
- Compatible with most types of coatings since it is silicone free.
- Nontoxic, noncombustible and nonflammable.
- Complies with LEED requirements for VOC.
Sethard L is recommended for new and old cementitious surfaces, such as concrete floors and granolithic paving. It should not be used to renovate concrete which is already disintegrating. Typical applications include:
- Factories.
- Warehouses.
- Garages, parking lots and driveways.
- Cold stores.
- Food processing plants.
- Industrial Plants.
- Shopping Malls.
- Health care facilities such as hospitals and clinics.
- Educational premises such as universities, schools and colleges.
- Showrooms, retail stores and shopping malls.
- Business facilities such as offices and lobbies.
Between 12 - 14 m²/litres on freshly poured concrete surfaces.
Between 9 - 10 m²/litres on old cured concrete surfaces.
Sethard L is available in 25 litre pails and 200 litre drums.
Store in a dry area out of direct sunlight between 5°C and 35°C.
Sethard L has a shelf life of 12 months from date of manufacture if stored in proper conditions and un-opened packs.
Sethard L meets the requirements of EN 1504-2 , principles 1.2 and 5.2.
