It is recommended when pouring large casting moulds to set silicone for at least 12 hours before demoulding.

Work in a well-ventilated area. Avoid contact with eyes and skin. Wear protective gloves and glasses when mixing and using. Over-exposure may cause sensitization. Uncured material can be removed with a solvent or methylated spirit followed by washing

Great product - silicone mould maker

Arrived quickly and was well packaged.
Very easy to use. I’ve never used this type of product before and had good success on the first use. Would recommend the product and Solid Solutions. This is the second product I have had shipped by them. Very good to deal with and fast service.

Super easy silicone!

Great product and simple to use. I’ve made a mould for a theatre prop involving high heat and it’s still going strong after numerous uses. Thanks!

Draw Face replacement

I needed to make a new Draw Face for my Bathroom Vanity Unit.
By removing another draw face and placing into a timber frame with some clearance around the Draw Face, I had the Mould ready for the Silcon 1;1 Mould maker solution to be poured in around it, I filled 10 mm above the Draw Face to create a firm base for the Silicon Mould that I was making.
After the silicon cured it was easily removed from around timber Draw Face. The Silicon Mould was a perfect replica of the Draw Face. All I need to do now is turn the Mould over and support the sides before pouring in FibreGlass resin.
When the Resin cured, I had new Draw Face, after some sanding to take the gloss of the Fibre Glass it was painted up and installed.
