Polycraft GP3481-F General Purpose RTV Condensation Cure Mould Making Silicone Rubber

This is the real deal. I'm a novice, and have been using it to create moulds of ornate Victorian papier mache cornice and other ceiling details to replace damp-damaged areas. I've just completed one large cornice section that's over a metre long. I don't have a vacuum chamber, so I followed MBFG's advice of painting the first layer on, then pouring the rest into the mould box. I can't believe how well the moulds have turned out - no bubbles at all, and no reaction with the various paints on the original cornice - unlike latex, which reacted badly to some gold paint. I was able to take a good section of the original cornice from the ceiling and build a mould box on the bench, but I understand that there's a thickener additive available that would allow you to do it in situ.

The container has some excellent instructions on it, but MBFB also has some great documents and videos - I'd recommend studying them first - but if you follow the directions carefully, you'll get excellent results like mine. I'd also recommend looking at some of the ancillaries - the plastic stirring sticks and breakout bowls were particularly useful.

I used to use a very well known product until I tried this.i is just as good with no bubbles and it's actually half the price per kilo than what I used to use , fantastic stuff!!

I had a go at mouldy making for the first time with this kit. It was very easy to use and really pleased to find out the harder and silicon were packaged in the correct weights for mixing. I also found, when I made a call to the company, a very helpful chap on the line, he gave some solid advice and some hints and tips. Great service, great product.👍👌

Dont look any furthur polly craft moulding and casting resins are second too none i have tried dozens of products over the years and these are far superior highly recommend

This is now my 'go to' silicone, the potlife with the red catalyst gives me plenty of time to set it up and pour my molds. The 27 shore ensures a good medium hardness that is strong enough for most projects and forgiving enough to allow easy removal of the pattern part. Highly recommended.

My project would've been sunk without this product. Took a little trial and error as I needed to make a mould of part of a cornice on the ceiling but once I got the technique right the mould was spot on. Very versatile, simple 10:1 ratio makes it easy to mix and sets well.

Coloured hardener makes it easy to check you have mixed thoroughly.

fast service,i placed my second order now.and have found the silicone very easy to use.site very user friendly and data sheets and info sheets helpful

I think the best silicone mould making rubber I had. Fast curing, very strong and ideal for brush on moulds when mixed with thixo. Wont change for any other silicone. Highly recommended.

Fast delivery, excellent product and kept me well informed, will use this as my new distributer
