Intermediate

Series 205, 210, N222, N223, N224, 233, 237, 238, 256, 257, 280, 281, N284, N285, 287
Note: Applying Series 248 to one of the listed primers or intermediate coats does not require sanding if the maximum recoat window for the primer or intermediate coat has not been exceeded. However, when applying Series 248 over smooth, slick, glossy surfaces it is good practice to uniformly degloss the surface by power sanding with 100 grit sandpaper, a 60 mesh sanding screen, or a coarse stripping pad to eliminate surface tension and any potential for possible contamination in the surface that may lead to fisheyes and/or poor adhesion. Sanding is not required when topcoating textured coatings (i.e. aggregate or colored quartz broadcast to refusal) with Series 248 if the maximum recoat window for the primer or intermediate coat has not been exceeded. Note: When applying Series 248 over a broadcast or mortar system, a 100% solids epoxy grout coat or Series 256 or 257 is required.

Recommended DFT

2.0 to 3.0 mils (50 to 75 microns) per coat. Note: Number of coats will vary depending on color, substrate (surface) and other variables. Contact your Tnemec representative.
