Industrial colour hardener (Dry Shake)
Introduction:
Industrial colour hardeners also know as Dry Shake, come as powders that are hand broadcast onto the freshly placed concrete and then worked into the surface with a float or a trowel. Unlike integral pigments, which colour the entire concrete matrix, hardeners colour only the top surface layer. Because the colour is concentrated at the surface, it tends to be more intense than integral colour and is considered as the best choice for Industrial floors.
Most shake on colour hardeners are a blend of pigments, finely graded silica sand, wetting agents and Portland cement. Colouring options come in a wider array of hues than integral colours, including various shades of blue and green. As the name implies, they also densify the concrete surface because they contain hard mineral aggregates and Portland cement, and so becomes the best choice for industrial and heavy duty floors. The result is a surface that’s stronger, more wear resistant, and less permeable to moisture and de-icing chemicals than standard concrete.
Because colour hardeners improve the strength and density of concrete surface, they are great choice for industrial floors, exterior slabs exposed to freeze –thaw cycles and de-icing salts and for interior floors exposed to heavy foot traffic and abrasion. It helps you gain LEED points under various sections.
Industrial floors densifiers
Introduction:
BGSB recommends Lithium based Concrete Densifier, which is colourless Lithium Silicate based chemical solution that increases the wear surface strength of industrial concrete floors subjected to pedestrian and vehicular traffic. Lithium Densifiers penetrates concrete surface to seal, densify, harden and waterproof them. Densified Industrial floors last longer, cost less to maintain, are safe to use and guaranteed to resist dusting for years after application. It is VOC compliant, odorless, environmentally safe and simple to apply.
Process:
Lithium silicate treatment deeply penetrates and reacts with the concrete to produce insoluble calcium silicate hydrate within the concrete pores. Treated surfaces will densify the concrete substrate into a hardened, chemically cured, homogeneous, concrete mass that resists abrasion and reduces oil and water penetration. This chemical ion exchange process begins after treatment and continues through the initial six months following application. The deeply penetrating chemical action leaves no film and will not alter the natural non slip texture of the concrete floor
Industrial floors densifiers Benifits
Excellent Penetration Lithium based Densiifers contains a highly reactive lithium catalyst, which achieves a much greater penetration into the floor surface and triggers a much faster and more complete reaction with the concrete than traditional sodium silicate.
Durability Lithium densifiers will outlast as it contains chemicals heavy in silica, which reacts withcalcium hydroxide in concrete, densifies and seals micro pores in the top layer of the concrete (“wearzone”), strengthens and hardens the surface, creating a permanent impregnation of the concrete floor. Lithium based densifier is breathable and UV stable. Will not yellow, discolor, peel or flake.
Greater Abrasion Resistance Maximum Hardening will effectively and significantly increase abrasion resistance in comparison to conventional sodium or potassium hardeners. Floors treated with lithium based densifiers will improve abrasion resistance by over 55% compared to untreated concrete.
Eliminates Dusting In ordinary concrete, tiny particles of dust are pushed to the surface through an upward force called hydrostatic pressure, resulting in efflorescence, which leads to dusting. Lithium densifier/ hardener eliminate efflorescence and prevents dusting making concrete easy to maintain.
Improves Stain Resistance By densifying and sealing the surface, it transforms a porous concrete floor into a floor that is dense enough to repel water, oil, and other contaminants, preventing them from penetrating the surface
Reduces or Eliminates ASR (Alkali Silicate Reaction) due to high lithium content. High concentrations of sodium or potassium salts, which will contribute to surface crazing and surface ASR, are not present in lithium based densifier and will not absorb water or contribute to floor sweating.
Reduces Tire Marks The rough, uneven texture of natural concrete causes tires to abrade, adding to their wear. A concrete floor treated with lithum based deinsifier will make the entire surface smooth, preventing this abrasion and leaving minimum tire marks on the floor.
Improves Condition of Old Floors As concrete ages, surface stress, delaminating, curled cold joints, and other problems can arise. Lithium hardeners/densifiers, combined with customized grinding and polishing technique, can remove the top surface layer of the old concrete and strengthen the floor, increasing its impact and abrasion resistance.
Little or No Production “Down Time” Cures quickly. Floor can be put in service immediately after the application process is complete. Due to the cleanliness of the process and the lack of toxic or hazardous chemicals, floors can often be serviced while the plant is in full production.
Cost-Effective Lithium improves performance, appearance and light reflectance of new and old floors. It will reduce energy bills. A treated floor will lower maintenance costs significantly through reduction in upkeep (no waxing), and reduced tire wear.
Planet Safe Lithium densifier/hardener is water-based, contains no solvents, non-toxic, no smell, complies with all known national, state and district AIM VOC regulations and IGBC INDIA, non-mutagenic & carcinogenic (safe in food preparation areas), non flammable, low odor, fast drying, easy to apply.
