What is Acriflex pH4 used for?
It's a high-performance waterproofing membrane for tanks and containment areas exposed to extreme pH levels (2–12) and harsh chemicals.

Can it be used in chemical tanks?
Yes — Acriflex pH4 is specifically designed for waterproofing tanks that hold acidic or alkaline substances.

Is it UV-resistant?
Yes — it withstands prolonged UV exposure without degradation.

Do I need a primer?
It depends on the substrate.

Use WATstop when:
• The surface is damp or affected by rising damp
• Applying over cement screed in contact with the ground (acts as vapor barrier)

Use Grip Primerwhen:
• Applying to smooth or non-absorbent surfaces (e.g., smooth concrete, metal, glass, painted walls)
• Preparing tile, linoleum, or previously coated surfaces for microcement or waterproofing

No primer is needed when:
• Applying to porous, absorbent substrates like brick, rough concrete, or masonry
• The surface is clean, dry, and structurally sound

How is it applied?
By brush, roller, squeegee, or spray gun. Two coats recommended.
