A liquid casting composition which is a precursor to a solid surface material comprising a liquid polymerizable component, polycarboxylic acid or salt thereof having at least two carboxylic acid groups and having a molecular weight in a range from 300 grams per mole to 5,000 grams per mole, and solid particles wherein the particles comprise:
- (a) first particles having a distribution in the range from 1 micron to 100 microns, and
- (b) second particles having a distribution in the range from 3 mm to 5 mm wherein the first particles are mineral and wherein the second particles are selected from the group consisting of mineral and polymer, and
- wherein the composition contains an ester of acrylic or methacrylic acid.
