Pick the Right System for Your Area

Wet Areas & Under-Tile (bathrooms, laundries, balconies)
Use a flexible liquid membrane over a suitable primer, then add joint bands/corners at all changes of plane before tiling.
– Explore Gripset membranes, primers and detailing accessories (e.g., 38FC, Under Tile Membrane, Elastoproof bands/corners). Paint World

Below-Grade & Retaining Walls (positive/negative pressure)
When you can’t access the external face, cementitious/negative-side systems shine (e.g., Drizoro MAXSEAL range). Pair with crack repairs and leak plugs as required. Paint World

Crack Repair, Active Leaks & Detailing
Stop active water with a rapid-set leak plug, stitch/bridge cracks with mesh/joint band, then over-coat with the specified membrane. (See Drizoro MAXPLUG, MAXMESH; Gripset Elastoproof.) Paint World+1

Priming & Surface Consolidation
Improve adhesion and even porosity with the right primer (e.g., E60 Water-Based Epoxy Primer) before your liquid membrane. Paint World

What a Matched Waterproofing System Delivers

• Continuity & flexibility across joints and corners (bands, corners, sleeves) for movement and vibration control. Paint World

• Adhesion & film build from compatible primers and membranes (fewer pinholes, better durability). Paint World

• Specialty problem-solving for negative-side damp, efflorescence and pressurised leaks (Drizoro repair and cementitious lines). Paint World
  
  

Buyer’s Checklist — Specify with Confidence

1. Substrate & exposure: Internal wet area vs balcony vs below-grade determines membrane type (flexible liquid vs cementitious). Paint World+1

2. Movement points: Include joint bands/corners at all floor/wall transitions, penetrations and puddle flanges. Paint World

3. Active water or cracks? Treat first with leak plugs/crack repair products before membranes. Paint World

4. Primer compatibility: Use the specified epoxy/acrylic primer for your membrane and substrate. (See E60 and Gripset/Sure Seal primers.) Paint World+1

5. Coverage & film thickness: Check litres and required wet/dry film build on the product page; plan for multiple coats. Paint World
   

Practical Tips from the Trade

• Surface prep first: clean, sound, dry and dust-free substrates maximise adhesion and reduce pinholes. Paint World

• Detail before you roll: install bands, corners and sleeves before the main membrane for continuity. Paint World

• Mind weather & cure: allow full cure between coats and before tiling/backfilling; follow each listing’s recoat windows. Paint World

• Negative-side fixes: where external access is impossible, cementitious systems (e.g., Drizoro MAXSEAL/SEALTIGHT) are purpose-designed. Paint World

Waterproofing FAQs

Do I need bands and corners if I’m using a “flexible” membrane?
Yes—membranes need reinforcement at changes of plane and penetrations to handle movement without cracking. Use bands/corners before the field coats. Paint World

What if the wall is already damp from the outside?
Consider negative-side/cementitious systems (e.g., MAXSEAL/SEALTIGHT) designed to resist water pressure from the substrate side. Paint World

Can I paint the membrane the same day?
Check the product page for recoat and tile times—fast-cure membranes exist, but cure windows matter for performance. Paint World

Which primer should I use?
Match primer to membrane and substrate; E60 water-based epoxy is a common pairing where specified. Paint World

How much product do I need?
Calculate based on required film thickness and m² area; highly absorbent or rough substrates may need more. Check each listing for coverage. Paint World
