Hi,

Im hoping to use some crystal clear resin, that doesn't go yellow and is clear all the way through but possibly add a blue colour to it. On two parts of wood for a table top, filling in the shakes and knots. So i would require the resin to allow the wood to move, but the resin to be really hard. Which of your resin do you think will be best? I have looked at the water clear polyester casting resin, but unsure its the right one. I would require the depth of the cast to be appox 60mm deep is this something i can do in on go, or do i have to do it in stages? I would like to sand the wood and the resin once finished and either oil it or lacquer it.

Please can someone advice on this.


Regards
Ben

GlassCast 50 is due in the next couple of weeks at most.  We are expecting similar pricing to the standard GlassCast so it's not too expensive.

There are not any other products  I would recommend.  I would not recommend the water clear polyester as it leaves a tacky surface and is quite prone to shrinkage which would be bad in wood as the resin would pull away from the knot hole edges as it cures. The bigger the volume and hence higher the heat  build up, the greater the shrinkage.  GlassCast has virtually zero shrinkage.
