Cemcrete Primer (formerley known as R.S. Cemprime), a single pack copolymer emulsion designed as a primer for Cemcrete SM and Cemcrete TX and for porous substrates. It stabilises and seals substrates effectively promoting adhesion that will allow self-smoothing compounds to be applied directly.
Cemcrete Primer (formerley known as R.S. Cemprime) is a single pack copolymer emulsion designed as a primer for Cemcrete SM and Cemcrete TX and for porous substrates. It stabilises and seals substrates effectively promoting adhesion that will allow self-smoothing compounds to be applied directly. It can also be used as a dust proof coating when applied as a tight coat by squeegee, roller or spray, depending on texture and finish. The product can be applied to vertical substrates to consolidate concrete and cement and other surfaces such as rock where it can disable asbestos fibres and stop these becoming airborne. Once dry Cemcrete Primer produces a water and alkali resistant polymer layer which both bonds to and strengthens the surface.
New Concrete Floors:
New concrete must be clean, sound, dry, fully cured and surface laitance removed by vacuum enclosed shot blasting or mechanical grinding, a minimum strength of 25N/mm2 is required.
Existing Concrete Floors:
Remove all dirt, oil, grease, old paint or any other surface contaminants by vacuum enclosed shot blasting, scarifying or mechanical grinding. Fats, oils or greases must be removed by mechanical means and detergent washing and make sure all residue of detergent is washed and removed by rinsing with clean water. Local repairs should be carried out using Resupatch.
External Surfaces:)
Where evidence of organic growth, lichen, moss etc. is apparent, surfaces must be thoroughly cleaned and should be treated with a long term fungicidal/biocidal treatment which should be allowed to react and then washed down. Careful attention should be given to areas in both horizontal and vertical surfaces such as cracks and joints where water penetration is possible.
Note: Care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.
Cemcrete Primer can be applied by brush, roller, squeegee or spray and worked well into the surface, at a rate of 7.23 m2 /kg and allowed to dry. Sound dense concretes should be dampened (with no free water) with a water spray. Open, highly porous substrates may require a second application to ensure the formation of a suitable surface film to provide a bond. Rates of coverage may vary substantially dependant on the surface preparation and finish of the concrete, rates given assumes a shot blasted surface with medium porosity. Once applied and dry it will not re-disperse in water.
N.B. Cemcrete Primer is not suitable for non-porous surfaces.
