Rapide Spray Mastic White, 200 ml

I bought this to seal a leak in a gutter joint on my conservatory,as I didn,t want to buy a large tube of filler and the skeleton gun that goes with it.Take care mask off surrounding areas (windows,PVC etc)as overspray is hard to remove from these places,I used the full can in short bursts from about 12 inches,and so far there have been no more leaks when it,s rained.The directions advise you not remove any dirt,dust,rust etc from the areas to be sprayed,as this is can strengthen the seal.Recommended,does the job.

Doesn't work for toilet leeks I used a whole can to cover the area and it's still spitting a leek.

Actually does what it says on the can! Used on garage roof and instant success!!Had heavy rain a couple of hours after using and was amazed to see it actually worked- I even found a place I had missed and this too is now waterproof!! Have just ordered another can to treat guttering on garage and house. Great product, great price, great service. Highly recommended!!!!!!!!!!

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.

Good at being mastic

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'

I used this on a drip on my soil pipe at the back of the toilet. It worked great but as I say it was only dripping. It’s been a few weeks now and everything is still dry 👍

I wanted to stop a drip from guttering. Came out like shaving foam, went everywhere, made a mess, did everything but stop the leak! Useless and not worth the money. I would be very surprised if this could stop or fix anything, don't waste your time or money with this.
