Series 20, 27, 66, L69, L69F, N69, N69F, 104, L140, L140F, N140, N140F, 161, 205, 210, 237, 238, 270, 273, 280, 281, 282, 287. Note: Before topcoating with Series 290, 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 for Series 210, 237, 238, 280, 281 and 282 is 24 hours. Refer to those product data sheets. Inorganic zinc-rich primers require an epoxy intermediate coat. 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 290 with itself. Note: When applying Series 290 over a broadcast or mortar system, an epoxy grout coat is required.
