Liquid Concrete Hardener

DESCRIPTION

DELTAHARD LCH is one component liquid concrete hardener based on metallic silicate with high silica content that can react chemically to produce a hard, abrasion resistant and dust-free finish. DELTAHARD LCH can be applied on any old or new floor concrete surface. It will absorp into the concrete surface and react with free lime and cement mortar forming a hard synthetic quartz-like material.

USES

• All concrete industrial floors, both old or new
• Car parks
• Warehouses
• Stores and shopping malls
• Schools and hospitals
• Concrete walls

ADVANTAGES

• Ready to use
• Easy to apply
• Non corrosive
• Improve chemical and abrasion resistant
• No peel, scratch or delaminate
• Fast drying
• Increase surface density and durability

APPLICATION Instruction

Surface Preparation

DELTAHARD LCH can be applied immediately after final finishing operations and when the concrete has hardened sufficiently at minimum 14 days of age. It can also be applied for old concrete.

The concrete surface must be clean and sound. Remove any dust, laitance, grease, oil, dirt, curing agents, impregnations, wax, coating and disintegrated material from surface. Grind the concrete to open the concrete pores. This will allow optimum penetration of DELTAHARD LCH

PRODUCT APPLICATION

Depending on size of work area, DELTAHARD LCH can be applied with a pump up sprayer or a high volume, low-pressure sprayer (HVLP). Apply DELTAHARD LCH to the surface evenly at the rate of approximately 80-200 m² per pail (20 kgs) or 4–10 m²/ 1 kg of Deltahard LCH. Lightly broom out any puddles immediately after the material has been applied. Allow DELTAHARD LCH to remain on the surface for 20-30 minutes. DO NOT LET ANY AREA DRY OUT during this time. Add more DELTAHARD LCH as needed in order to maintain a uniformly wet surface. After material has completely penetrated the surface, continue grinding and polishing to the intended final surface profile and desired finish. For best results, use an auto scrubber and water to remove residual slurry between abrasive disc grits.

CLEAN UP

Use water to clean tools and equipment. Treatment is environmentally friendly and requires no special or hazardous disposal methods.

TECHNICAL DATA

HEALTH AND SAFETY

DELTAHARD LCH is caustic materials which can be harmful to the skin and eye. During use, avoid contact with the skin or eyes. Wear suitable protective clothing – eye protectionand gloves. Good ventilation is necessary when applying DELTAHARD LCH. In case of contact with the skin, rinse with plenty of clean water, then cleanse thoroughly with soap and water. In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice. If swallowed seek medical attention immediately.

FIRE

DELTAHARD LCH is non-flammable materials.
