• Non-staining – Water based with no flammable or toxic constituents. 
• Fully Biodegradable 
• Any residue left on the formwork is easily removed 
• No VOCs 
• WRAS approved product

Application:

Apply uniformly by low pressure spray or fine spray watering can in temperatures above freezing to top face of freshly placed concrete immediately after completion of placing and compaction.

An excess of surface water due to bleeding of an over-wet mix will hinder penetration of retarder, therefore any excess water should be removed before treatment.

After treatment protect from exposure to wind or early applied heat as this may evaporate the retarder carrier before it has sufficiently penetrated the concrete surface. Any absorbent material covering the concrete, such as hessian, should not come into contact with the Safetard Liquid as this will soak up the retarder preventing penetration into the concrete surface.

On thick sections and in warmer temperatures a second application should be made on the same working day.

Removal of Retarded Matrix: Remove by low pressure water jetting and/or brooming or wire brushing in two directions at right angles to each other. Under general conditions this should be done early on the day after placing but if this is not possible a further application should be made at the recommended rate as soon as possible on the day after placing.
