Frequently asked questions
-
What's in the ACTFLEX 400 Clear Bathroom and Balcony Repair Kit?
CompatibilityThe kit contains the full ACTFLEX 400 Clear over-tile waterproofing system: clear-finish membrane, application tools (brush, roller), reinforcement tape for problem areas, and step-by-step instructions for over-tile remedial waterproofing.
-
Why apply over existing tiles?
PerformanceDemolishing and retiling a leaking bathroom or balcony is expensive and disruptive. ACTFLEX 400 Clear bonds to clean existing tiles and creates a clear waterproofing layer that preserves the original look while stopping leaks for up to 5 years.
-
What prep is required?
InstallationCritical: clean the existing tiles thoroughly with detergent and a degreaser, remove all mould (treat with bleach if needed), regrout failing joints with epoxy grout, and let everything dry. Then apply 400 Clear per the supplied instructions.
-
Will it work on natural stone or coloured tiles?
CompatibilityACTFLEX 400 Clear is genuinely clear once cured, preserving the appearance of underlying tiles. On porous natural stones, test a small area first - some stones may darken slightly under the clear coating.
-
Is the repaired surface AS-compliant?
ComplianceACTFLEX 400 Clear is a remedial system - it extends the service life of a previously waterproofed (and now leaking) surface. For new-build wet area waterproofing, AS3740:2021 specifies an under-tile membrane like ACTFLEX 906 WPU.
