DIRECTIONS FOR USE

• Test the product in an inconspicuous area first

SURFACE PREPARATION

• Ensure the surface is dry, clean and firm, being free from dust, laitance, oil, grease, wax and other contaminants. Varnish, paint and old adhesive must be removed off the substrate prior to application of PrimeX or overcoated with Ultrabond

• For difficult to tile over surfaces, such as glazed tiles, vinyl tiles, paint, varnished floors etc. ParexGroup recommend the use of Davco Ultrabond coating

APPLICATION

1. Shake the container before use.

2. Apply PrimeX to the substrate using a broom, brush roller or squeegee, then allow the primer to dry. Note: The primer is dry when all milkiness disappears.

3. Under hot, windy conditions (temperature above 30oC), it is recommended to wet down any concrete slabs with clean water prior to priming, so that the primer does not flash dry. Whilst wetting down the floor, do not allow the water to pool or pond on the surface. The substrate should appear matt, with no signs of glistening water just prior to application of the primer.

4. Extremely porous concrete slabs should be wet down with water, as per instructions above, to prevent flash drying of the primer.

5. Once PrimeX is applied, it is recommended that the substrate be subsequently coated within 24 hours, otherwise, you risk the chance of recontaminating the surface with site dirt and dust. If the area is left uncovered for more than 24 hours, then it must be wiped down with clean water to remove site dirt and dust, and re-priming prior to tiling / waterproofing.
