"I can only assume previous comments were due to too small a hole being cut. I cut full width of nozzle end and found it very easy to push out of the tube. It flowed beautifully into a large crack and was very easy to smooth. One warning ... any spils need to be cleaned up immediately. Will use again!"
"An expensive but handy way of doing patch up jobs. Had no problem expelling it from the cartridge as other seem to have had. It is a funny consistency but easy to apply and form, just does take a long time to dry and can feel spongy until it is fully cured. Will be buying more as it matches well with my existing mortar and hamstone."
"As other reviewers mentioned, its a bit stiff in the tube, and hard to come out using a gun. With the risk of not damaging my mastic gun, i binned it, and used a ready mix cementone repair and pointing set to finish off the work. Not recommended."
"Bought this product as it fitted perfectly to my needs plus it is produced by a tried and tested name all be it with other products. However I found it almost impossible to get any real volume of material out of the tube. I put so much pressure on one mastic gun it bent the handle. Have made sure the tube and nozzle are clear but it appears the sandy texture prevents it passing through a standard 310 ml tube nozzle. Will be returning the product for a refund."
