Hi,

I've bought the clear cast epoxy resin for a "valley" table top I'm making. The total thickness will be approximately 28mm. The resin will only do 15mm in one pour. How do I go about doing the 2nd pour? Do I have to wait until it's full cured (several days??!) will the surface need sanding (keyed) before I pour the 2nd layer?


Also, I will need to sand the resin once fully cured, because the want the wood either side of the resin to be visible (not covered in resin) so will I need to go through all the grits 120-1500 wet dry and then use a cutting compound to polish it?


Any help will be greatly appreciated!

Thank you.

Thank you for your reply, it was very helpful!

I did the first seal coat which went very well, I got a few bubbles which I managed to get rid of using my hot air gun. I let tha set (about 30hrs) it was rock hard and not tacky. I sanded the surface like you said, making sure it was all sanded and then cleaned the surface. I then did the first main pour, but this time I had thousands of tiny bubbles appear, non of which I could pop with the air gun. I mixed the resin for about 4 mins until totally smooth, any idea on what could have gone wrong?

I'll try and post a photo, but it's very difficult to see then.

For some reason it won't upload my photos even though I've made them really small.

I used the 3 pot method to make sure only one pot was used to mix the resin.
