Mould Master British Gypsum Fine Casting Plaster 1Kg, White, 20 x 15 x 1 cm

This moulding gypsum is fantastic! Easy to mix, pours smoothly, and sets perfectly without cracking. The finished casts come out detailed and strong, exactly what I needed for my projects. Very high quality and reliable—definitely worth every penny.

The best quality! Value for money! Very effectiveness and nice natural colour.

I did a cast, for a dog paw imprint, as per attached photo. 3d printed a flexible cylinder, some masking tape to hold it. Wiped cooking oil on the imprint 3 times and voilà. The imprint seems to be made of modeling clay. After an hour or two I was able to take them apart. Good quality, easy to use, dries quickly, value for money. I went with 10% extra water, to have the mix more watery. Happy with my purchase.

Fantastic plaster that makes casting a dream. No airbubbles in the process, it mixes in easily with water creating fine pastw . It was touch hard after 1 hour as advertised but I should have kept it a bit longer in the mould as it was still not completely dry. Also for fine bits it probably should be reinforced with some fiber. Overall it is perfect for silocone mould casting as a hobby craft and for professional use. I will definitely order more!

Great product which gave a superb smooth finish, ideal for Model Railway buildings and scenery, thank you. TM.
