Drawback we had to use rechargeable gun as thick. Biggest issue is it doesn’t cover much area. I was doing between my slabs and one tube only did two and a half so beware how much you need.

Drawback we had to use rechargeable gun as thick. Biggest issue is it doesn’t cover much area. I was doing between my slabs and one tube only did two and a half so beware how much you need. ### ⭐⭐⭐⭐ Good product *by A***N on 21 July 2026* Good product for little maintenance jobs struggled to get it out of tube though ### ⭐⭐⭐⭐⭐ Excellent stuff! *by M***N on 7 May 2026* This stuff was excellent. Pretty easy to use and seemed to adhere well. Only time will tell so I’ll submit another review update in about 6 months. It was a good colour match for grey mortar and seems to have dried pretty quickly. The nozzle was wide enough for the mortar and all in all it looks decent for a novice. Pretty cheap for this sort of repair. Make sure you soak the tube in warm water before using as this really helps with easing the application. All in all it’s great! ## Frequently Bought Together - SX Trade Strength Buff Mortar Repair Cement 300ml - Ready to use repair mortar for Pointing jobs & Damaged Masonry Joints - Adheres without primer on Damp Surfaces - Interior & Exterior - ProDec Extra Strong Caulking Gun - fischer 523858 Express Cement-Sand --- ## 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.ec/products/583369093-sx-siroflex-mortar-repair-cement-buff-300ml](https://www.desertcart.ec/products/583369093-sx-siroflex-mortar-repair-cement-buff-300ml) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-08-16*
