Question 1

Is this adhesive truly invisible, and will it stay clear over time?**

Accepted Answer

It dries to a transparent, flexible film. On most light-colored surfaces, it's virtually invisible. However, on very dark or matte surfaces, some users note a slight glossy sheen. It is designed to resist yellowing from UV exposure, but like many clear coatings, prolonged direct sunlight may cause minimal changes over several years.

Question 2

I have a leak on my bathroom shower tile. Is this product suitable, and will it stay sticky?

Accepted Answer

Yes, it's a popular choice for sealing shower corners and tile grout. It adheres well to ceramic and porcelain. The coating cures to the touch, but some users in humid environments report a slight residual tackiness. To minimize this, ensure you apply a thin, even coat. For high-touch areas, allowing extra cure time (up to 72 hours) is recommended.

Question 3

How long can I expect the waterproof seal to last, especially outdoors?**

Accepted Answer

Performance varies based on surface preparation, weather, and traffic. Many users report successful seals lasting 1-3 years on roofs and window sills. For the longest lifespan on outdoor surfaces, apply to clean, dry areas and consider a second coat. It's a durable repair solution, but for areas with extreme constant wear or movement, a more specialized sealant may be better long-term.

Question 4

The bottle is 35oz. Is this too much for a small job, and how should I store it?

Accepted Answer

The 35oz size is cost-effective for multiple projects or larger areas like sections of a flat roof. For a single window sill or a few shower tiles, you will have plenty left over. The good news is it stores well! Ensure the nozzle is completely clean and the cap is screwed on tightly. Many DIY enthusiasts on forums like Reddit keep their bottle for years, using it for various small leaks as they arise.

Question 5

What surfaces is this NOT recommended for, and what's a better alternative?**

Accepted Answer

We do not recommend it for underwater repairs (like inside aquariums), constantly submerged areas, or for sealing large structural cracks in foundations. It's also not ideal for surfaces with constant heavy foot traffic. For a more textured, rubberized coating or for sealing moving joints (like between a tub and tile), a product like Flex Seal or a high-quality silicone caulk might be a more targeted choice. Our adhesive excels as a versatile, brush-on sealant for static seams and surfaces.
