PS Liquid Retarder
PS Liquid Retarder produces an exposed aggregate finish, suitable for keying construction joints or to enable excellent bonding of subsequent coatings or toppings.
PS Liquid Retarder should be spray – applied to fresh horizontally cast concrete at a rate of 3 – 5m 2 /ltr, using a plastic sprayer, immediately after compacting with a wooden float. Avoid using a steel trowel as this may s eal the surface and negate the retarding action. Direct sunlight or high temperature will also reduce the retarding time.
