Building epoxy river tables can have its fair share of challenges so we decided to share a few of our tips and tricks! 1) Make sure you select the right kind of epoxy. Not all epoxies are created equal and many epoxies on the market are meant for pouring in thin layers. For pours like this, we use @ecopoxy FlowCast! 2) Make sure your form is built from the correct materials. We use HDPE (high density polyethylene) for our forms but you can also use plywood and sheathing tape. 3) Calculating how much epoxy you need: in inches, multiple the rivers length by the depth by the average width and divide by 61 to get the total number of litres required. 4) Make sure your form is sealed correctly and level! We construct our forms using silicone and screws to ensure that we have no leaks. We double and triple check our table before pouring to ensure it is level. 5) Once the epoxy cures, you can flatten your piece 4 different ways: sanding (recommended for small pours), using a planer (good for narrower/smaller pieces), using a router sled or lastly, using a CNC. - Here’s what we used to build this table: WOOD: walnut EPOXY: @ecopoxy FlowCast PIGMENT: @ecopoxy Caribbean FINISH: @rubiomonocoatusa Pure 2C Oil - All of these supplies can be purchased at We have free shipping on orders over $300 to Canada and the USA. - #tipsandtricks #tips #Advice #communityovercompetition #knowledge #howto
