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.

May produce an allergic reaction. - Safety data sheet available on request. - READY TO USE MORTAR - Ideal for small pointing jobs and removes the need to mix sand and cement. - NO PRIMER REQUIRED - Adheres well to most surfaces without the need for a primer. - EASY TO APPLY - Cut the cartridge seal, attach the supplied V shaped nozzle, and use a good quality applicator gun as the material can be firm straight from the cartridge. - APPLICATION TIPS - Apply only in dry weather and keep the surface dry for at least five hours to allow proper curing. - TEMPERATURE REQUIREMENTS - Ensure both the product and the substrate are above 5°C for best performance. - EASY TO CLEAN - Tools and hands can be cleaned easily with water. - CONTENTS - 1x SX Siroflex Contractors Mortar Repair Cement, 300 ml, Cement grey ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C69MG58L | | Best Sellers Rank | 256 in DIY & Tools ( See Top 100 in DIY & Tools ) 2 in Cement | | Brand | Siroflex | | Colour | Grey | | Compatible Material | Metal, Plastic, Stone, Wood | | Container Type | Cartridge | | Country Of Origin | Netherlands | | Customer Reviews | 4.2 out of 5 stars 1,308 Reviews | | Global Trade Identification Number | 05032822003575 | | Included Components | 1 x SX Cement Grey Mortar Repair Cement 300ml | | Item Form | Paste | | Item Package Quantity | 1 | | Item Volume | 300 Millilitres | | Item form | Paste | | Manufacturer | Siroflex Lte | | Manufacturer Part Number | SXMORTRC310CG | | Material | Acrylic | | Model Number | SXMORTRC300CG | | Number of Pieces | 1 | | Other Special Features of the Product | Ready to use, no primer required | | Special feature | Ready to use, no primer required | | Specific Uses For Product | Construction and Repair | | Specific uses for product | Construction and Repair | | Unit Count | 300.0 millilitre | | Viscosity Level | High | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** Siroflex - **Item form:** Paste - **Material:** Acrylic - **Special feature:** Ready to use, no primer required - **Specific uses for product:** Construction and Repair ## Images ![SX Siroflex Mortar Repair Cement Grey, 300ml | Ready to Use Formula, Repairs Damaged Masonry Joints, Adheres to Damp Surfaces For Interior & Exterior Use - Image 1](https://m.media-amazon.com/images/I/61PISmmrqrL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good but runs out quickly *by M***N on 25 July 2026* This is easy to use and saves time trying to get right mixture doing it yourself. 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 Cement Grey Mortar Repair Cement 300ml - Ready to use repair mortar for Pointing jobs & Damaged Masonry Joints - Adheres without primer on Damp Surfaces - Interior & Exterior - Faithfull FAISGTPT6 Soft-Grip Pointing Trowel 150mm (6in) - Fischer 523856 Express Mortar Cement Grey --- ## 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.hr/products/534611876-sx-siroflex-mortar-repair-cement-grey-300ml-ready-to-use](https://www.desertcart.hr/products/534611876-sx-siroflex-mortar-repair-cement-grey-300ml-ready-to-use) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-22*
