Crommelin Catalyst PWC Waterproofing

Crommelin Catalyst PWC – Biochemical Modified Silicate Waterproofing Solution

Crommelin Catalyst PWC is a high-performance, biochemical-modified silicate solution designed to penetrate deep into concrete, forming a water-insoluble calcium silicate hydrate gel complex that permanently seals cracks, pores, and capillaries.

Unlike traditional coatings, Catalyst PWC doesn’t require re-application or maintenance, ensuring lasting waterproofing and protection against chloride ions. Its UV stability prevents yellowing, while moisture vapor permeability allows concrete to breathe without compromising its strength. Trafficable after the first watering, Catalyst PWC is the ideal solution for concrete protection in high-traffic areas.

Colour Accuracy Disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.

Product Disclaimer: Ensure you read all product, technical and safety data sheets prior to application as liability falls on the applicator. All products must be applied in accordance with manufacturer’s recommended method.
