Series 291 | CRU

Generic Type Aliphatic Polyester Polyurethane
Common Usage Extremely hard, chemical-resistant polyurethane floor coating with superb flow characteristics. Excellent resistance to abrasion, wet conditions, corrosive fumes and chemical contact. Gloss and color retention among the best of air dried finishes. Note: For horizontal surfaces only.
Colors Available in the 16 standard StrataShield colors and limited custom colors. Contact Tnemec Company for availability. Note: Certain colors may require multiple coats depending on method of application and finish coat color. When feasible, the preceding coat should be in the same color family (blue, gray, etc.), but noticeably different.
Finish Gloss
Primers Horizontal Concrete: Series 201, 203, 205, 280, 281, 287.
Intermediate Series 104, 205, 210, 237, 238, 239, 280, 281, 287
Note: Before topcoating with Series 291, any Tnemec epoxy exterior exposed for more than three weeks must be scarified or reprimed with itself. Mechanically abrading or power-sanding is the preferred method of scarification. The maximum recoat time of Series 210, 237, 238, 239, 280 and 281 is 24 hours. Refer to those product data sheets for more information. Note: Scarification using a power sander and 100 grit sandpaper, No. 60 mesh sanding screen or a coarse stripping pad is required if topcoating Series 291 with itself. Note: When applying Series 291 over a broadcast or mortar system, an epoxy grout coat is required.
