2. Apply: Dip the included brush into the gel and apply a smooth, even layer over the target area.
3. Dry: Allow the first coat to cure for 2–3 hours.
4. Reinforce: Apply a second or third coat as needed for enhanced protection.
5. Cure: Keep the area dry for 24–48 hours to allow a full, robust waterproof membrane to form.

Q: How many coats should I apply for the best waterproofing result?
