||Aliphatic Moisture Cured Urethane
||Extremely hard, chemical-resistant urethane floor coating with superb wear characteristics. Excellent resistance to abrasion, wet conditions, corrosive fumes and chemical contact. Excellent gloss and color retention. Low odor characteristic allows for use near occupied space.
||Supplied as a clear coat. May be tinted with available Series 821 color pack in the 16 standard StrataShield colors and limited custom colors. Color packs sold separately. 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 shoud be the same color as the topcoat. Note: Series 44-600 UV Blocker may be added to Series 248 (clear) for increased resistance to ultra-violet light. Refer to the Series 44-600 product data sheet for more information.
||Semi-gloss. Note: The gloss level can be reduced by adding two Part C filler components to each kit.
||Concrete: Series 66, 66HS, 161, 161HS, 201, 205, 237, 238, 256, 280, 281, 287. Note: Series 248 can be applied directly to concrete if a single coat urethane sealer is desired.
||Series 66, 66HS, 161, 161HS, 210, 237, 238, 256, 280, 281, 284, 285, 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 is required.
