Frequently Asked Questions

What materials can I use this PU foam sealant on?

It is highly versatile and bonds strongly to PVC, masonry, brick, glass, steel, aluminum, and wood. However, it is not recommended for PE (polyethylene) or Teflon surfaces.

Why is the front-end foam filling technology better?

This technology ensures a smoother application with significantly fewer air bubbles. This leads to a more consistent, uniform bond and higher structural integrity compared to standard foaming methods.

How long does it take for the sealant to dry?

The sealant features ultra-fast surface drying. While exact times depend on humidity, it is designed to let you move to the next step of your project much faster than traditional sealants.

Is it suitable for outdoor use in hot or rainy climates?

Yes. The formula is specifically engineered to cure effectively in humid and high-temperature environments without losing its adhesive strength or stability.

What is the main difference between the Grade A+ and Grade D options?

The primary difference is the concentration of the main material. Grade A+ contains 86% active material for maximum bonding strength, while Grade D contains 38%, offering a more budget-friendly solution for lighter tasks.

Which packaging size should I choose?

We offer 300ml, 500ml, and 900ml sizes. For small home repairs, 300ml is sufficient, while the 900ml size is ideal for large-scale construction or professional contractor use.
