  • My original idea was more like that - but I definitely want a one piece top - it’s about 3.2m long and I can’t cast it in the bathroom so it needs to be light and flexible/strong enough to carry upstairs without cracking.
    So I’m thinking Glass Fibre Reinforced Concrete is the way to go.
    It’s possible to buy all the ingredients separately- but they’re not easily available in the Uk. Concrete countertops are big in the States. So I’ll probably end up buying a just add water mix.

    I already know how I’m making the mould -melamine, silicone etc. I’ve got a fair bit of casting experience from sculpture days.

    I need to borrow or hire a spray hopper thing to spray the inside of the mould with slurry.
    They’re not used so much in the UK I think.
