Frequently Asked Questions

How does WS-802 achieve "instant" traffic opening?

WS-802 is a pressure-sensitive material. Unlike traditional asphalt that requires cooling or chemical curing, WS-802 hardens and gains strength as vehicles drive over it. The compaction from traffic actually improves the repair.

Can it really be applied during rain or freezing temperatures?

Yes. WS-802 is designed for all-weather performance. It maintains its bonding properties in temperatures as low as -20°C and as high as 60°C, and it can be applied directly into wet potholes.

What is the expected lifespan of a repair made with WS-802?

When applied correctly, WS-802 repairs are considered permanent with a durability rating of over 5 years, often outlasting the surrounding original pavement.

Does this material require heavy machinery for installation?

No. One of its main advantages is simplicity. It can be applied by a single person using basic tools like a shovel or hand tamper. For large areas, traffic flow provides the necessary final compaction.

Is WS-802 environmentally safe?

Absolutely. It is VOC-free and produces zero emissions. It is an eco-friendly alternative to solvent-based cold mixes and requires no energy-intensive heating.

What is the shelf life if a bag is opened?

WS-802 has an exceptional shelf life of up to 5 years. Any leftover material in an opened bag can be saved and used for future repairs without losing its effectiveness.
