What is hardener for concrete?
Concrete hardeners are a permanent, transparent sealer that protects underlying concrete from damage caused by chemicals and contaminants. Liquid concrete hardeners create a chemical reaction when applied to concrete, penetrating pores.
What is Lapidolith?
Lapidolith® is a magnesium- flurosilicate concrete hardener and dustproofer that bonds chemically with the concrete to strengthen and harden floors that are porous, readily absorptive, and only moderately hard.
How much concrete hardener do I need?
Allow at least 1 litre per 4m2 per coat (two coats are required). Improves the abrasion resistance of dusty or poorly cured concrete by up to 3 times. Has good resistance to alkali solution and petroleum solvents but poor resistance to strong acids.
Why is concrete hardener used?
Surface hardeners are applied to a concrete surface after it is smoothed and left to dry. They help to improve the concrete’s abrasion and chemical resistance, thus significantly improving the durability of the concrete surface. This also helps to reduce the permeability of the concrete.
How do you make concrete hardener?
1. A hardener composition for use in producing waste-containing shaped cement articles by mixing broken concrete, cement, waste, and water and shaping the mixture, said hardener composition comprising 4.0 to 13.0 wt. % of sodium carbonate, 5.0 to 10.6 wt. % of potassium carbonate, 5.2 to 11.2 wt.
What is hardener used for?
In some mixtures a hardener is used simply to increase the resilience of the mixture once it sets. In other mixtures a hardener is used as a curing component. A hardener can be either a reactant or a catalyst in the chemical reaction that occurs during the mixing process. A hardener may also be known as an accelerator.
What is the floor hardener?
Floor hardener is a particle form composition made in size graded specifications to be used by mixing with cement & grit/stone chips mixture to give extra hardness to the concrete floor without affecting cement chemistry.
What is a Densifier hardener?
In a nutshell, a concrete densifier is a chemical hardener that is most commonly applied on top of the concrete slab after placement, and if polishing the slab, it is used during the process of refinement.
Which is the best concrete densifier and chemical hardener?
LIQUI-HARD ®. Concrete Densifier and Chemical Hardener. DESCRIPTION. LIQUI-HARD concrete densifier and chemical hardener compound is a proprietary, water-based, ready-to-use, clear silicate liquid, formulated with chemically reactive raw materials to harden and dustproof concrete.
What kind of liquid is Liqui hard concrete?
LIQUI-HARD concrete densifier and chemical hardener compound is a proprietary, water-based, ready-to-use, clear silicate liquid, formulated with chemically reactive raw materials to harden and dustproof concrete.
How does masterkure HD 300wb concrete hardener work?
How does MasterKure HD 300WB work? MasterKure HD 300WB is a magnesium-fluorosilicate concrete hardener and dust proofer that bonds chemically with the concrete to strengthen and harden floors that are porous, readily absorptive, and only moderately hard. What are the unique features of MasterKure HD 300WB?
Can you use Liqui hard with Shake on hardeners?
LIQUI-HARD can successfully be used in conjunction with shake-on hardeners. The INDUROSHINE® system from W. R. MEADOWS combines green certified concrete polishing and diamond grinding equipment with LIQUI-HARD to create a unique, high sheen, wear-resistant concrete floor.
