||Aliphatic Moisture Cured Urethane
||Extremely hard, chemical-resistant urethane floor coating with superb flow 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. Note: For horizontal surfaces only.
||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 should be the same color as the topcoat. Note: Series 44-600 UV Blocker may be added to Series 247 (clear) for increased resistance to ultra-violet light. Refer to the Series 44-600 product data sheet for more information.
||Concrete: Series 66, 66HS, 161, 161HS, 201, 205, 237, 238, 256, 280, 281, 287. Note: Series 247 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: Before applying Series 247 over coatings with a smooth, glossy surface, thoroughly scarify the previous coating using a power sander and 100 grit sandpaper, No. 60 mesh sanding screen or a coarse stripping pad to eliminate surface tension. Failing to uniformly degloss the entire surface or thoroughly clean all surface contamination may lead to fisheyes and/or poor adhesion. Sanding or scarification is not required when topcoating textured coatings (i.e. aggregate or colored quartz broadcast to refusal) with Series 247 if the maximum recoat time of the previous coating is met. Note: When applying Series 247 over a broadcast or mortar system, an epoxy grout coat is required.
