ROCKCOTE AE Primer is an anti efflorescent primer designed for painting over fully cured site-mixed cement render to stop efflorescence blooming through topcoats. Tintable to strong colours it also provides a slip resistant surface for easy application of paints or trowel on coatings.
Suitable: for priming site-mixed cement renders and mortar jointed brick or block walls to provide a barrier to efflorescence that can occur on these substrates. Allow 28 days for site-mixed renders to cure before applying ROCKCOTE Anti Efflorescent primer. Can be used interior and exterior, and can be top coated with paint or render.
Sheen: matt, anti slip surface.
Colours: can be tinted to a wide range of colours. Specify the colour of your topcoat and we will tint to a base colour to suit this - usually about half strength of your topcoat colour.
Application: by brush, roller or spray. Can be thinned up to 5% with water.
Coverage: approximately 6 sq.m/ltr
Drying time: 4 hrs
