DESCRIPTION
CEMIX GROUT SEALER is stain resistant water based penetrating clear waterproofing sealer that can be used for impregnating and sealing of the grout that resists water, oil and acid based contaminants. There is little or no impairment of the grout’s ability to breathe and exhibits a good moisture vapour transmission rate. It can be successfully applied on damp grout. The application does not produce any discolouration of the surface. Recommended for use on cementitious sanded and un-sanded porous grout joints. Effective for interior and exterior applications.
TYPICAL APPLICATION/USES
ADVANTAGES
SUBSTRATE PREPARATION
The grout surface should be free of efflorescence, dust, grease, wax, oil, dirt and all other friable materials and contaminants likely to prevent the sealer bonding. Ideally, this sealer should be applied on new freshly laid and cured tiled joints. The grout should have cured for a minimum of 48 hours before application of this sealer. Make sure there are no existing stains or marks as these will be visible through this clear finish sealer. Apply using a soft bristle paint brush or sponge paint applicator. Allow a minimum of 30 minutes of drying time between coats. Always test apply on an area first to approve the look and feel.

APPLICATION
Mildly shake the container before using. It is very easy to apply using the spray bottle. Spray along the grout joints and then wipe excess overspray off the tiles. Typically this would be done after 4 – 5 minutes which allows it time to tack to the grout however it is recommended that a test tile is used to ensure sealer can be completely removed prior to application of a large area. Sealer will penetrate and seal all the fine pores. Can also be applied using an artist’s brush. Should apply 2 coats and should wait for ½ – 1 hour between coats. Each coat should be enough to be soaked into the grout surface – do not over apply to cause ponding and formation of a milky layer. Allow to cure for 24 – 48 hours before any water is applied. To check – put some drops of water on the grout sealed surface and water should bead and not be absorbed by the grout. Do not apply if temperature is below 5°C as it will take extended time to cure and dry.
