Cemcrete SM is a water-based, polymer modified cementitious coating designed to be laid over a wide range of floor and wall surfaces to provide a smooth, durable finish strongly bonded to the substrate with a degree of flexibility to enable the accommodation of movement in the structure of the building. Cemcrete SM can be applied in exterior or interior situations.
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.
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 making sure all residue of detergent is washed and removed by rinsing with clean water. Local repairs should be carried out using Resuscreed PA. 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 the existing floor coating.
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.
Pour the liquid component into the supplied mixing bucket.
Whilst mixing add the aggregate component slowly and mix for a further 2-3 minutes using a high-speed drill and paddle to ensure the mixture is lump free and consistent. The mixed material should be applied immediately and consistently using the relevant application method.
Each coat should be evenly applied and allowed to dry before the next is applied. Where specific finishes are required it is recommended that trials are undertaken to ensure that the techniques are understood and able to be used on the surface available.
Cemcrete SM should be applied where there are good drying conditions and the ambient temperatures of the area and substrate should not be allowed to fall below 5°C throughout the application and the curing period.
Cemcrete SM can be applied by a variety of techniques including trowel, pin rake, brush, squeegee etc. Each of these techniques will leave unique tool marks in the cured finish and these should be taken into consideration prior to application.
