At the inlaws and have time on my hands so I'm reading some mosaics books and they say to seal wood with "clear acrylic sealer" and of course all the pics only show the back of the packages and there are no names suggested so can anyone make some recommendations?
Also, if I am using a hard plastic base, do I need to do anything special so the adhesive will stick?
My plan is to use weldbond glue until I decide to use a glass base...
thanks

If the hard plastic substrate bends at all, the mosiac will be short lived. If it does not, then you can lightly sand the plastic to take off the shine. Then the Weldbond should work very well. Sealers should be used to preserve the grout, keep growths/algae from growing, and protect the adhesive which in the case of Weldbond is water soluble. Any good sealer will work. Follow the directions and apply it multiple times if it is a penetrating sealer. I use TileLab for mine and it takes about three applications. Always test the sealer on your glass/tile before using it so there are no surprises. Many sealers cause a haze which comes off with cleaning while TileLab does not haze or stain.
