Rapide Spray Mastic White, 200 ml

I tested it on some terracotta pots and it does dry into a solid thick paint-like layer.I then sprayed it on the inside of an old metallic waste water drain hopper that had a 2-3 mm hole in it. I formed a nice thick layer with it but on contact with the water and detergent it shriveled up but the plugged hole was still intact. Let's see how long it will last.On spraying, I noticed if you don't hold it at a particular angle it will only spray air. I'm guessing that if you keep doing that it will lose all its pressure whilst all the silicon remains in the can making you think there is little product in the can.

Thin to apply don’t like giving bad reviews it didn’t last long I used it for the plug hole under the sink perhaps I didn’t use it correctly would advise put cloth down it’s quite messy

Just waiting for the rain again

As previous people have commented, it is a bit messy and sprays everywhere.A different type of top would be better.Much cheaper than other products, but unfortunately in my case, has not stopped a leak on a plastic joint below bathroom sink, despite two 'sprayings'

Have had this for over a year and used once . You must ensure that the area is very dry prior to application. Once dried. Will set very well as using silicone mastic

stops leaks

Worked for a while, but didn't last for that long.

No problems.
