Potential Outcome: Penetration is blocked; treatment won’t absorb, leaving areas unprotected.
Adheseal Best Practice: Confirm history of prior treatments. If water beading indicates repellents, do not apply. Where block walls require pore closure, use the dedicated EP™ Concrete Block Sealer.
Potential Outcome: Reduced penetration and incomplete reaction, risking uneven performance.
Adheseal Best Practice: Clean with EP™ Cleaning Products, rinse thoroughly and allow to dry. Apply by low-pressure spray to saturate the surface uniformly.
Managing negative-side moisture where access for external membranes is impractical, while maintaining coating compatibility for finishes.
Apply E P Waterproofing System™ by low-pressure spray at ~5–7 m²/L to saturation. The internal densification reduces permeability and supports negative hydrostatic resistance (tested to 60 psi). Allow dry, then proceed with paint/lining per spec.
Verify substrate is clean and dry; maintain ambient >10 °C during application and >8 °C for 24 h. Plan finishing after the substrate is dry; full cure typically 6–7 days.
Preventing rapid moisture loss from fresh toppings into old slabs, which can compromise curing and bond.
Treat the existing slab with E P Waterproofing System™ to densify and control absorption before placing the new layer. This supports proper curing and improves bond at the interface.
Spray to even saturation and allow to dry before placing the new concrete. Always confirm absorption; if the surface won’t take product, reassess suitability.
Preventing saponification, blistering and peeling on alkaline cementitious substrates.
Treat render with E P Waterproofing System™ to neutralise free lime/alkali and reduce moisture ingress. Once dry, proceed with coating systems as specified.
For new plastering, rinse to remove dust, allow to dry, then apply at ~1 L/4–5 m². Allow 12–24 h penetration before finishing; full cure in 4–5 days on plastered areas.
It is not a film-forming coating. The treatment penetrates the substrate and reacts within the gel pore system, densifying the matrix to waterproof from within, so it cannot peel or wear away like a surface film.
Once the substrate is dry after application you may paint; on plastered substrates allow 12–24 hours penetration and drying before finishing. Full cure progresses over several days.
Yes. Shotcrete’s higher cement content increases reaction potential. Expect slightly higher uptake (lower m²/L) due to absorption; spray to saturation and allow to dry.
Do not apply over substrates previously treated with silicone, siloxane or solvent-based repellents, or where the product won’t absorb. For porous concrete block walls, specify EP™ Concrete Block Sealer.
| Application / Use Case | Key Benefit | Primary Trades |
|---|---|---|
| Basements/retaining walls (negative-side) | Internal densification reduces water ingress; negative hydrostatic resistance | Waterproofers, Builders |
| New toppings over old slabs | Controls absorption for improved curing and bond | Builders, Concreters |
| Rendered/painted façades | Helps prevent saponification; longer coating life | Painters, Builders |
| Shotcrete linings | Enhanced reaction with high cement content | Waterproofers, Civil |
Clean substrates to remove dust, oils and contamination; rinse and allow to dry. Confirm no prior silicone/siloxane/solvent-based treatments.
Use EP™ Cleaning Products as needed, rinse thoroughly and ensure the surface is dry before treatment.
Apply when air/surface >10 °C; maintain >8 °C for 24 h. Keep materials ideally 18–35 °C.
Apply by low-pressure spray (back-pack or equivalent) at ~20 psi to saturate the surface uniformly.
Typical rate ~5–7 m²/L on dense substrates; shotcrete may require higher uptake due to absorption.
Allow to dry before foot traffic or finishing. On plaster, allow 12–24 h penetration before coating.
Wear safety glasses and suitable gloves during application. Avoid contact with eyes and prolonged skin exposure.
Use with adequate ventilation. For interiors, ensure air movement during and after spray until surfaces are dry.
Non-flammable. Keep containers closed when not in use. Prevent release into drains and waterways.
Seek medical attention immediately in all cases of serious exposure.
Remove dust, laitance, oil/grease and contaminants. Clean with EP™ Cleaning Products, rinse and allow to dry. Ensure surface/air >10 °C and remains >8 °C for 24 h.
Apply by low-pressure spray (~20 psi) to saturation at ~5–7 m²/L. Allow to dry before traffic/finishes.
EP™ Cleaning Products (prep only)Rinse to flush dust on new work; dry completely. Treat at ~1 L/4–5 m² from the top down; allow 12–24 h penetration.
Paint once dry; expect full cure in approximately 4–5 days for plastered areas.
—Ensure clean, dry and free of repellents. Assess pore size; some quick-stage block has oversized voids.
Use EP™ Concrete Block Sealer where pore/void structure is too large for standard penetration.
