Use a paint roller where you can as it's easier to spread. **Q: How much will 21kg cover.** A: I think it will cover 1 sq metre per kg **Q: Can it be applied directly to new wood** A: Hi, the Everbuild Liquid Roof is used for waterproofing of flat and pitched roof structures. If the wood has been treated this may react or compromise the bonding of the Liquid Roof, we would recommend a test in this instance. Liquid Roof can be used on untreated wood. ## Frequently Bought Together - Everbuild Liquid Roof | All Weather Roofing System Ideal for Concrete, Mortar and Metals - Slate Grey - 21 kg - Special Fleece for roof Sealing, roof Fleece, Fleece for Liquid Plastic, stabilisation Fleece, Construction Fleece Fabric for reinforcing Liquid Sealing, Polyester Fleece 110 g/m² 0.15 x 50 m - Everbuild Liquid Roof All Weather Roofing System, Slate Grey, 7 kg --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/91774395-sika-sikaroof-liquid-roof-pu-all-weather-roofing-system-slate](https://www.desertcart.jp/products/91774395-sika-sikaroof-liquid-roof-pu-all-weather-roofing-system-slate) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-14*
