Have used before so sure it will be good. Good price aswell. Review: Sealed my concrete steps - I wanted to buy a sealant for my concrete steps as rain was seeping through them into a void under my house. I found it easy to apply with a brush and so far it seems to be working well. Instead of sinking into the concrete, the rain forms puddles on the surface. There was enough in the pack to apply a second coat which I will be doing shortly. I am having a resin coating applied to the steps in a few weeks but the resin is porous so hopefully the sealant will still work underneath it. ## Features - 402 Waterseal - Size: 5LTR - Brand: Everbuild ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0012LETNK | | Best Sellers Rank | 2,773 in DIY & Tools ( See Top 100 in DIY & Tools ) 67 in Sealers | | Brand | Sika | | Colour | Clear | | Compatible Material | Brick, stone, plaster, concrete | | Customer Reviews | 4.4 4.4 out of 5 stars (5,460) | | Global Trade Identification Number | 05029347004255 | | Item Dimensions | 18 x 20 x 24 centimetres | | Item Form | Liquid | | Item Weight | 5 kg | | Manufacturer | Sika Everbuild | | Manufacturer Contact Information | Sika Everbuild 41 Knowsthorpe Way, Leeds LS9 0SW | | Manufacturer Part Number | XWAT5LAB | | Material | Silicone | | Model Number | XWAT5LAB | | Number of Items | 1 | | Style Name | Single | | Surface Recommendation | Wall, floor, roof | | UPC | 764210982531 | | Unit Count | 5000.0 millilitre | | Water Resistance Level | Water Repellent | ## Product Details - **Brand:** Sika - **Item dimensions L x W x H:** 18 x 20 x 24 centimetres - **Item weight:** 5 kg - **Material:** Silicone - **Style:** Single ## Images ![Everbuild 402 Water Seal – High Performance – Long Lasting Protection From Water Damage – Solvent-Free Formula – Water Repellant – 5 Litre - Image 1](https://m.media-amazon.com/images/I/61uODZ-Jk-L.jpg) ## Questions & Answers **Q: can it be applied by brush?** A: Yes, this product can be applied by brush or spray but must be second coated before the first coat has dried in. So larger areas need to be broken down into smaller areas if brush applied. **Q: Can this be used on a brick fireplace indoors please?** A: I can't see why not. I've only used it on the inside of a garage wall a concrete floor & rendering all of which have been successful. It can stain though so be careful of drips. **Q: Can i use this on a slate roof? a roofer has said the slates are become porous, so it sounds ideal, but someone has said no in the q and a - why?** A: Hi. Unfortunately this is only intended as a water seal for wall applications and slate isn't porous enough for the 402 to soak in to create an efficient seal. **Q: Can this be used to seal polished plaster ?** A: I would not have thought so as polished plaster has a none porous outer layer which would not let the water seal seep into! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product. *by T***A on 5 April 2026* Arrived on time, good product, have not been able to use yet due to weather.
