Watco Universal Sealer Dustproofer strengthens and binds together weak, poor quality concrete (and similar surfaces) to leave a dust free, hardened surface. It has many uses, making it so versatile. As well as hardening and strengthening concrete, it can be used as a primer to reduce the porosity of highly absorbent surfaces (such as sand and cement screeds), prior to applying a water based coating. It can be used on brick, blockwork, plaster walls and block paving to help strengthen and bind the sandy joints together. It is quick and easy to apply with just one coat. Universal Sealer Dustproofer is most suited for use in warehouses, factories, machine shops, storage rooms or anywhere that would benefit from a multi-purpose penetrative and virtually odourless dustproofer. Watco Universal Sealer Dustproofer is breathable and safe for use in confined areas. It has an A+ VOC emissions rating with a very low VOC content.
Where to use
- Ideal for previously untreated concrete and masonry surfaces
- Use on floors and walls, in factories, warehouses, machine shops
