Description

Cemcrete Primer (formerley known as R.S. Cemprime) is a single pack copolymer emulsion designed purposely as a primer for porous substrates, such as concrete or masonry. 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 or roller depending on texture, and finish. Once dry, Cemcrete Primer produces a water and alkali resistant polymer layer which both bonds to and strengthens the surface.

Please note that this product has a minimum order quantity of 43 x 4.7KG

Preparation


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 or Resuscreed 45.

Existing Floors (previously coated)

All previous coatings and loose floor paints must be removed by mechanical preparation as described in the above section and primed as specified. if the old resin flooring cannot be removed, then please consult with our technical team for advice on intercoat adhesion and suitability, as it may not be compatible with existing floor coating.

Where Cemcrete Primer is applied to masonry/concrete surfaces, care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.



Application


The ambient temperatures of the area and substrate should not be allowed to fall below 10°C throughout the application and the curing period. Where possible it is recommended that the application area is <75%RH, heated to a minimum temperature of 15°C and time is allowed for the ambient and substrate temperature to stabilise prior to installation.

Cemcrete Primer can be applied by squeegee, brush or roller and worked well into the surface, at a rate of 5 m²/l. 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.

On highly porous surfaces, or when used as a dust proofer, a very dilute (1:1 with water) wash may be applied to obtain maximum penetration Once dry this should then be followed by an application of the standard material (neat) to the surface to build the film thickness.

N.B. Cemcrete Primer, is not suitable for non-porous surfaces.
