Abstract Spreadable flooring compositions comprise a well-blended mixture containing 8-20% by wt. based on the composition of a curable glycidyl polyether of a bisphenol, having a viscosity of 100-3000 centipoises at 75 DEG F., 1-10% by wt. based on the composition of a curing system comprising a polyamide of a polymeric fat acid and a polyamine, the system having a viscosity of 5000-18,000 centipoises at 75 DEG F. and being present in an amount of 1-50% by wt. based on the polyether, and 60-90% by wt. based on the composition of a graded filler having a sieve analysis of:- .U.S. Standard.% by wt .Sieve No..retained .14.4-7 .16.12-18 .18.20-26 .20.8-22 .30.14-30 and such that substantially 100% by wt. of the filler will pass through a No. 10 sieve and a maximum of 35% by wt. will pass through a No. 30 sieve. The curing system may also contain an amine such as an alkylene polyamine or a tertiary amine and the compositions may also contain a pigment and/or a poly(butylglycidyl ether). The filler may be sand or SiO2, and may contain an abrasive such as 30-grit aluminium oxide. The compositions may be used for surfacing floors, roadways, stair treads and vehicle beds.
