How to Point Patio Slabs with the Piping Bag Method | Strongest DIY Mortar Joint Finish

In this video, I show you how to point patio slabs using the piping bag method — a technique I’ve tested over years of paving and slab work. It's fast, clean, and produces stronger, longer-lasting mortar joints than traditional brushing or trowel methods. I’m using a 3:1 mortar mix with added SBR and waterproofer, piped into the slab joints using a heavy-duty piping bag. If you’re pointing Indian sandstone or concrete slabs, this guide will help you achieve professional-looking results. 🧱 TOOLS & PRODUCTS USED: • Piping Bag: https://amzn.to/4f9psxD • SBR Additive: https://amzn.to/3AdshOL • Waterproofer: https://amzn.to/3NAWElj 🧰 MY FULL TOOL KIT: https://renovation-dan.co.uk/my-tools/ ☕* Support the Channel:* https://buymeacoffee.com/renovationdan 🎧 Uncut Builds Channel:    / @ambientwoodworking   📢 Some links are affiliate links that help support the channel — thank you for watching and supporting my work!
