This.is an industrial product, the finish coat is not intended to look pretty, any competent diyer can apply it but a couple of hours working with the stuff and your arm feels like it’s about to fall off! Like all cement products drying time depends on ambient temperature and background moisture, although you have plenty of working time before it starts to go off it is important to mix it up according to the makers instructions(I’ve been in construction for over 50 years and the old adage applies now as then – when all else fails read instructions!) too much water and the surface will crack on drying, too little water and it won’t come off the brush,won’t stick to the wall and will leave gaps for water to rush through. If you leave a gap water will find its way through and as was all waterproofing products if you can find that and stop the water at source so much the better. if your cellar was dry before then you don’t need this stuff you need to find what has changed! Final word, the prices do vary, this supplier offers very competitive price as well as a good delivery service Review: Works really well. - Great stuff - easy to mix and use and does a great job of keeping the damp at bay. ## Features - Causes serious eye damage. - Causes skin irritation. - May cause respiratory irritation. - Becomes a part of the structure for permanent water proof protection - Dual surface and migratory crystalline action ensures complete waterproofing and will also reactivate should future water contact occur ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00CM5ERFK | | Best Sellers Rank | 51,778 in DIY & Tools ( See Top 100 in DIY & Tools ) 71 in Waterproofers | | Brand | KA | | Colour | Grey | | Compatible Material | Shower, Sink, Tub, Fixture | | Customer Reviews | 4.6 out of 5 stars 580 Reviews | | Included Components | 1x Tanking Slurry | | Item Dimensions | 35 x 35 x 35 centimetres | | Item Form | Paste | | Item Type Name | Tanking Slurry | | Item dimensions L x W x H | 35 x 35 x 35 centimetres | | Item form | Paste | | Manufacturer | KA | | Manufacturer Part Number | 5.06E+12 | | Material | Polymer-based | | Model Number | TANKING | | Number of Items | 1 | | Style | Compact | | Style Name | Compact | | Surface Recommendation | Shower, Sink, Tub, Fixture | | UPC | 798256189043 700461622550 | | Water Resistance Level | Waterproof | | Water resistance level | Waterproof | ## Product Details - **Material:** Resin - **Brand:** KA - **Style:** Compact - **Item dimensions L x W x H:** 35 x 35 x 35 centimetres - **Compatible material:** Shower, Sink, Tub, Fixture ## Images ![KA Tanking Slurry 25Kg Grey - Image 1](https://m.media-amazon.com/images/I/51r7qO58LGL.jpg) ## Questions & Answers **Q: What is the coverage of this product?
