## Description

Siroflex SX Mortar Repair Cement - A ready to use high quality hardening joint repair filler based on acrylic dispersions and additives. Specifically developed to repair damaged masonry joints quickly without the need to mix sand and cement. Will adhere perfectly without primer even on damp surfaces.

Review: I bought two tubes, it was easy to use although it was a little hard to squeeze out at first. Before starting you need to ensure any loose material is cleared out of the gaps to be filled otherwise the filler can fall out. The colour is a light grey which blended well with my cement which is around 30yrs old, I’m happy with the results. Like the Bruce Willis film it Dries Hard. I know!
Review: Good enough although it could maybe do with a little more moisture through it in order to help stick to a dry surface. Easily rectified and other than that it does its job well enough.

## Features

- READY TO USE MORTAR - Perfect for small pointing jobs, saving time on mixing sand and cement
- NO PRIMER - Will give a perfect adhesion to most surfaces without the requirement of a primer
- EASY TO APPLY - Simply cut the cartridge seal and screw on the pre-cut 'V' notched nozzle. Using a skeleton gun, apply the product into the gap ensuring a good solid fill.

*by E***H on 31 August 2025*

Second time buying this product to fill some exterior cracks and damaged mortar. Was an absolute pain to get out of the tube both times, give up with the gun and just cut the top off and applied direct from tube. Adhesion was great, curing time wasn't too bad overall considering the varying depths needing repair. Would definitely recommend and buy again despite the difficulty of it coming out the tube.
