Gripset BRW PF Tape is a self-adhesive butyl rubber sealing band engineered for critical flashing and detailing in commercial wet area waterproofing. This system provides a high-strength fabric face for mechanical membrane adhesion and a 70% elongation rate to accommodate structural movement without rupture.
For specialist technicians, the peel and stick application creates an instant seal on PVC puddle flanges and metal penetrations, eliminating the curing downtime associated with traditional liquid bond breakers. While the tape achieves primer-less adhesion on clean metals and plastics, it must not be left as an exposed flashing or used in negative hydrostatic pressure applications.
To prevent delamination, avoid application to damp substrates unless pre-treated with a moisture-stable primer.
Frequently Asked Questions
Is Gripset BRW PF Tape compliant with Australian waterproofing standards?
Yes, Gripset BRW PF Tape is designed as a bond breaker and sealing system for use in applications meeting AS 3740 and AS 4654.2. When used as part of a Gripset membrane system, it provides the required movement accommodation for internal and external wet areas, ensuring your installation meets NCC requirements.
Can I use this tape on a damp concrete floor?
No, the tape cannot be applied directly to damp surfaces as it will compromise the butyl rubber adhesion. If you are dealing with damp concrete or high residual moisture, you must first prime the substrate with Gripset E60 vapor barrier. Once the primer is dry, the tape can be applied with full confidence.
Do I need to use a primer on metal flashings or PVC pipes?
Generally, priming is not required for non-porous surfaces like galvanised iron, aluminium, and PVC plastics, provided they are clean and free of oil. Simply degrease the surface, ensure it is dry, and apply the tape directly. For highly porous masonry or dusty timber, use Gripset GP primer to ensure maximum grab.

Applying Gripset BRW PF Tape: Enhanced Protocols & Best Practices
-
Preparation & Measurement
Clean the substrate thoroughly and measure the length of the joint or penetration to be sealed.
Cutting
Use sharp scissors or a utility knife to cut the tape to size, allowing for overlaps at corners.
Pro Tip: For long runs, peel only 200mm of release paper at a time to maintain control and prevent the tape from sticking to itself. -
Installation & Bedding
Remove the backing paper and press the butyl side onto the substrate with the fabric face exposed.
Tooling
Use a spatula or small roller to force out air bubbles and ensure 100% contact with the surface.
Timing: Immediate. Overlays and membranes can be applied as soon as the tape is rolled flat.
Limitations & Safety
Product Limitations
Not suitable for expansion joints or negative hydrostatic pressure applications.
Cannot be used as an exposed flashing; must be finished over with a membrane, coating, or tile system.
Do not apply when surface temperatures are below 5°C or above 30°C.
Safety & Handling Requirements
Personal Protective Equipment
Wear safety shoes and suitable gloves. While the material is non-hazardous, gloves prevent skin contact with the aggressive butyl adhesive during handling.
Emergency First Aid
Eyes:
Wash out immediately with water. Seek medical advice if irritation persists.
Skin:
Flush skin with water. Seek assistance if redness or irritation occurs.
Swallowed:
Rinse mouth with water. Do NOT induce vomiting. Seek medical advice.
Gripset BRW PF Tape Application Guide
Metals & Plastics (PVC, Colorbond, Galvanised Iron)
Surface Preparation
Surfaces must be mechanically sound and free of rust or oxidation. Wipe with a clean, lint-free cloth to remove dust and oils.
Primer Requirements
No primer typically required
Direct application is suitable for dense, clean non-porous surfaces.
Porous Masonry (Concrete, Brick, Render)
Surface Preparation
Must be fully cured and dry. Remove laitance, curing compounds, and dust via grinding or wire brushing if necessary.
Primer Requirements
Primer required for porous surfaces
Highly porous surfaces must be primed to consolidate dust and ensure a stable bond.
