Non-Corrosive Metallic floor Hardener

DESCRIPTION

Deltahard MT is a ready-to use dry shake floor hardener that have speciality using metallic aggregate. Deltahard MT provides more hard wearing, abrasion resistant and high impact resistant topping into your industrial floor. Deltahard MT consists of non-oxidizing graded metallic aggregates, Portland cement, additives that mixed under special supervision to give you the best performance.

USES

Deltahard MT is highly recommended for area subject to heavy and/or frequent traffic, area exposed to have a high impact such as engineering workshop, warehouse.

ADVANTAGES

• Increase the wear resistance of concrete floor up to three times than untreated concrete floor.
• Reduces surface dust formation
• High resistance to abrasion
• Improves resistance to oils and greases
• Improves resistance to impact
• Easy to be applied, just sprinkled into the freshly placed concrete, and even finish is obtained when property smoothed.

CONSUMPTION

Light duty : 3 kg/m²
Medium duty : 5kg/m²
Heavy duty : 7kg/m²

INSTRUCTION FOR USE

Deltahard MT is applied by using dry shake method, sprinkled into the top of fresh concrete, The concrete slab itself should contain minimum cement content of 300 kg/m³. The concrete mix should bedesigned to minimise segregation and bleeding. Free water; cement ratios of less than 0.55 are required. The concrete should have a slump of 8-12 cm.

Level the freshly poured concrete by means of a vibrating beam. As soon as the plasticity permits, smooth the concrete preferably using a mechanical trowel. Application of Deltahard MT can only begin when the base concrete has stiffened to the point when light foot traffic leaves an imprint of about 3 mm. Beware of excess water occurs from the fresh concrete, all excess water (bleeding concrete should be managed in good practice.

Deltahard MT is applied in two stage; first application using 1/2 up to 2/3 of the material required for the eventual end use. Broadcast the mix evenly by hand or with suitable device and wait until the water in the concrete has evenly moistened Deltahard NM, then use wooden float or use power float. Darken colour of the concrete floor indicated moisture absorption from the concrete. It is important that the surface should not be overworked. Second application commenced immediately.

After the first application, using the remaining material. Deltahard MT has to be thrown evenly over the concrete surface.

Deltahard MT can be used a protection on bay edges of concrete floor. This area is likely suffers particularly heavy impact or wear. To give an additional protection; sprinkle Deltahard MT on a strip 100-150 mm wide along the bay edges, steel trowel into the surface, this method can also used in areas where saw-cut transerve control joint are located.

A method of curing should be made using suitable curing compound. Start curing immediately after final finishing.

LIMITATIONS

Deltahard MT can not be used in areas exposed to acids and their salts or other materials known to rapidly attack or deteriorate concrete containing normal type Portland cement. Do not apply to concrete containing calcium chloride or concrete having greater than 3% air entrainment.

For light vehicle traffic 7 – 10 days
Fully cured after 28 days
