SBS Base Treatment Agent

​

Product Description

The SBS Base Treatment Agent is a high-penetration, solvent-based primer specifically designed to enhance the adhesion of SBS modified bitumen waterproof membranes to various substrates. This primer effectively seals, strengthens, and smooths the application surface, ensuring optimal bonding between the waterproofing membrane and the base layer.

​

Key Features

​

✔ Strong Adhesion Enhancement – Creates a solid bonding interface between the membrane and the substrate.
✔ Deep Penetration & Surface Sealing – Improves substrate compactness, reducing dust and surface porosity.
✔ Fast Drying & Easy Application – Quickly evaporates and is ready for membrane installation in a short time.
✔ High Compatibility – Suitable for various substrates, including concrete, cement mortar, asphalt, and metal.
✔ Improves Waterproofing Durability – Enhances the performance and lifespan of the SBS modified bitumen waterproof system.​
