Tartaric Acid: chemical resistance of ASP floors
How each ASP epoxy and polyurethane flooring product performed when fully immersed in tartaric acid, from ASP's chemical resistance guides (December 2022).
Summary5% at 20°C: excellent for ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB, ASP-creteSL, ASP-creteMD, ASP-creteRT, ASP-creteVS and ASP-coatPU; not resistant: ASP-coatWBE.

Ratings come from 30 × 30 mm samples cast at each product's prescribed thickness, cured for 7 days and fully submerged at 20–25°C. On a real floor, a spill only touches the surface, so performance is usually better. Elevated temperatures accelerate chemical attack. How to read these ratings.
Questions about tartaric acid
Which ASP floors resist tartaric acid (5% at 20°C)?
Rated 5 (excellent, no significant deterioration after long-term contact): ASP-primeStd, ASP-coat500, ASP-coat1000, ASP-coatSL, ASP-screedPTS, ASP-screedSTB, ASP-creteSL, ASP-creteMD, ASP-creteRT, ASP-creteVS and ASP-coatPU. Not resistant (0): ASP-coatWBE.
Is epoxy flooring resistant to tartaric acid?
Some ASP epoxy systems are rated excellent for tartaric acid at 5% at 20°C. Check the exact concentration and temperature in the table, as ratings change with both.
Is polyurethane flooring resistant to tartaric acid?
Some ASP polyurethane systems are rated excellent for tartaric acid at 5% at 20°C.
