Application Guide
- Surface Preparation: Ensure all surfaces are structurally sound, stable, dry, clean, and free of dust, loose material, oils, grease, form release agents, curing compounds, and any other contaminants. Ensure surfaces are free from protrusions to achieve a continuous even film build.
- Priming: Use a primer on porous and warm surfaces. For internal applications, Everflex WBP is typically sufficient. For external applications like roof decks and balconies, Everflex VBS is recommended. Apply primer as per the primer’s TDS and apply Everflex Aqua-Ban within 2-24 hours.
- Application: Mix Everflex Aqua-Ban thoroughly before use. Apply the first coat using a brush or roller to achieve an even and consistent coat of approximately 0.75mm wet film thickness. Once the first coat is dry, apply a second coat at a right angle to the first coat at the same thickness. Verify wet film thickness with a gauge. Minimum two coats are required to achieve a dry film thickness (DFT) of 1mm.
- Waste Outlets and Penetrations: Floor wastes and puddle flanges should be rebated into the floor. Fill all gaps and perimeters with Adheseal PU or Hi-Flex MS sealant.
- Gaps, Joints, and Corners: Apply a fillet with Adheseal PU, Hi-Flex MS sealant, or suitable bond breaker to internal corners and over sheet joints. For dynamic cracks/expansion joints, use Adheseal Elastoband or Butyl Tape systems.
- Cure Time: Allow approximately 48 hours cure time at 25°C and 50% humidity before tiling.
- Clean Up: Clean tools and spills with water while the product is still wet. For cured product removal, use mechanical means.
Limitations
- Do not use when temperatures are below 10°C or above 35°C
- Limited UV resistance – Not designed for long-term UV exposure and must be tiled or topped
- Do not apply on damp, wet, or contaminated substrates
- Not suitable as an exposed membrane
- Not suitable for areas subject to negative hydrostatic pressure or rising damp
