Sylmasta Superfast Aqua PW
Sylmasta Superfast Aqua PW is a fast-setting epoxy putty in a 114g stick for wet-surface and underwater repairs on metal, concrete, wood, fibreglass, many plastics, and glass, including WRAS-listed potable-water pipework. High adhesion on damp or submerged substrates keeps leak and joint work moving when drydown is impractical.
- WRAS-listed approval supports drinking-water pipe and fitting repairs.
- Cohesive bond forms within approximately 15–20 minutes for rapid return to light duty.
- Once cured white, the repair can be tapped, drilled, machined, filed, or painted.

Key Features
- WRAS-listed formulation is certified for pipes and fittings carrying drinking water.
- High adhesion on damp, wet, and underwater substrates supports salt- or fresh-water leak work.
- Approximately 5-minute work life then cohesive bond within 15–20 minutes for fast emergency repairs.
- Bonds to metal, concrete, wood, fibreglass, many plastics, glass, and more indoors or out.
- Cures white and machines cleanly: tap, drill, saw, grind, file, or paint after set.
- Solvent-free and VOC-free; unused stick stays fresh in original packaging for later cuts.
- Resists water, chemicals, hydrocarbons, and temperature extremes in aggressive plant environments.

Frequently Asked Questions
Which wet or submerged jobs suit Sylmasta Superfast Aqua PW?
Superfast Aqua PW is formulated for high adhesion on damp, wet, or underwater substrates in salt or fresh water. Typical work includes sealing leaks and rebuilding fittings on metal, concrete, wood, fibreglass, many plastics, and glass where drydown is impractical. WRAS approval means it is certified as safe on pipes and fittings carrying drinking water.
What work life and strength timeline does Aqua PW publish at ambient conditions?
Sylmasta Superfast Aqua PW lists a work life of approximately 5 minutes. Within 15–20 minutes it hardens and forms a cohesive bond. After one hour the putty can be used under light loads; working strength develops between two and four hours; maximum properties are reached after 24 hours. For sealing pipe leaks, the TDS recommends waiting the full 24 hours for full pressure resistance.
Does Superfast Aqua PW carry drinking-water approval?
Yes. Superfast Aqua PW has WRAS approval and is certified as safe to use on pipes and fittings carrying drinking water. Confirm site acceptance of WRAS-listed materials before specifying for your potable circuit.
What hardness and strength values appear on the Aqua PW TDS?
After full cure (24 hours), Superfast Aqua PW lists Shore D hardness of 96, lap shear tensile strength on steel of 6.2 MPa, and compressive strength of 83 MPa. Density is 2.0 g/cm³ with shrinkage under 1%. Values are typical for information only.
What upper service temperatures can cured Superfast Aqua PW handle?
The Superfast Aqua PW TDS lists continuous service up to 120°C and intermittent service up to 150°C. Store unused stick out of direct sunlight in dry, frost-free conditions between 5°C and 24°C for a 24-month shelf life from manufacture.
Can cured Sylmasta Superfast Aqua PW be machined or painted?
Yes. Once cured white, Superfast Aqua PW can be tapped, drilled, screwed, sawed, machined, ground, filed, or painted. The epoxy is solvent-free and VOC-free, non-flammable, and will not shrink or pull away when setting.
