Product Description

EVERBUILD ACCELERATOR AND FROSTPROOFER is a chloride free liquid admixture for set acceleration and rapid hardening of cement based mortar, concrete, screeding and render. Also provides frost protection in the wet mortar during the setting period; even in sub-zero temperatures (down to-“8°). May also be used neat with cement as a plugging aid. Accelerator and Frostproofer is non-corrosive to metals so may be used with brick ties. Conforms to EN934-2 Table 7.

Benefits

Faster finishing times even in cold weather.
Provides frost protection down to -8^oC in wet mortar.
Chloride free non corrosive formula.
Optimises mould usage.

Areas For Use

Floor screeds
External/Internal cement based rendering
Concrete (not structural)
Suitable for use as an emergency repair plugging aid when mixed neat with cement.

Application

Work should be carried out in accordance with the methods outlined in the Code of Practice BS5628 Part 3 for protection and use of mortars at low temperatures. All materials used must be free from ice and the temperature of the mix prior to placing must not be less than 4^°C.

AS AN ACCELERATOR: Add to gauging water at an addition rate of 2.5 to 5 litres per 50kg cement depending on the degree of acceleration required. Note: remember to reduce required quantity of water accordingly.

AS A FROSTPROOFER: Add to gauging water at an addition rate of use 2.5ltrs/50kg cement for protection down to-“4° and 5ltrs/50kg cement for protection down to-“8°, again, reducing required quantity of water accordingly.

AS A PLUGGING AID: Mix neat with fresh cement and place immediately.

NOTE: Concrete must be covered after placing until the minimum strength is obtained or until the temperature rises above freezing. Do not use with high alumina cement. Following is an indication of setting times at 20° (use as a guide only)
