How to Use Tape Water Activated Syntho Glass 4 x 20 (Step-by-Step)
Using this tape isn’t difficult, but technique matters. Follow this guide for a strong, long-lasting cure.
Step 1: Clean the Surface
Remove:
- Dust
- Oil
- Rust flakes
- Loose paint
- Moisture pockets
A clean surface = strong bond.
Step 2: Put on Gloves
The resin is aggressive. Avoid skin contact.
Step 3: Activate the Tape
Submerge the tape in clean water for 5–10 seconds.
You’ll feel it begin to warm that’s the resin activating.
Step 4: Wrap Tightly
Overlap each layer by 50%.
The goal is tension and compression.
Step 5: Smooth It Out
Use gloved hands to compress the wrap and push out air bubbles.
Step 6: Let It Cure
Full cure time: roughly 30 minutes.
After that, you’ve got a rigid composite-like casing.
Safety Tips When Using Syntho Glass Tape
These tapes are strong which means the curing resin deserves respect.
- Wear gloves always
- Don’t apply to pressurized leaks over 60 psi unless reinforced
- Avoid open flames
- Don’t use inside drinking-water systems
- Use outdoors or in ventilated spaces
