Application Guide
- Prepare the surface: Ensure all surfaces are clean, stable, and free from contamination. Repair any cracks or deformities.
- Prime the substrate: Apply Everflex WBP for internal areas or Everflex VBS for external surfaces, following the primer's TDS instructions.
- Apply Everflex WPUV: Mix thoroughly, then apply the first coat using a brush or roller at a 0.75mm wet film thickness. Allow drying before applying a second coat at right angles to the first.
- Ensure a minimum of two coats for a total dry film thickness (DFT) of 1mm. More coats may be needed depending on surface conditions.
- Wait for a minimum curing time of 48 hours at 25°C and 50% humidity before tiling or other finishes.
Limitations
- Not suitable for use below 10°C or above 35°C
- Should not be applied to wet, damp, or contaminated substrates
- Not suitable for areas with negative hydrostatic pressure or rising damp
- Foot traffic should be limited to maintenance levels
