Series 237 | Power-Tread

Generic Type Modified Polyamine Epoxy
Common Usage A multi-purpose, broadcast, slurry broadcast or mortar applied floor topping system installed at 1/8” to 1/4” thickness. Protects against impact, abrasion and mild chemicals.
Colors Clear or pigmented. Can be factory or field-tinted (Series 820 Field Tint) in 16 StrataShield colors and certain custom colors. Contact your Tnemec representative for additional information. Note: Colors may not be uniform and are not intended to be finish coats—see Topcoats listed below. Note: Epoxies chalk and yellow with age, extended exposure to UV and artificial lighting. Lack of ventilation, incomplete mixing, miscatalyzation or the use of heaters that emit carbon dioxide and carbon monoxide during application and initial stages of curing may cause amine blush, possibly affecting adhesion of subsequent topcoats.
Surfacer/Filler/Patcher Series 206, 215. Note: A repair kit of 201, with Part C fumed silica, is available for small patching/surfacing repairs. For more extensive repairs and additional information, contact your Tnemec representative or Tnemec Technical Services.
Primers Self-priming or Series 201, 203, 241
Topcoats Series 247, 248, 252SC, 280, 281, 282, 284, 285, 286, 287, 290, 291, 294, 295, 296, 297. Note: If Series 247, 248, 290, 291 or 297 is selected for the finish coat, an intermediate coat of Series 280, 281 or tinted 237 is required. If Series 247, 248, 285, 294, 295 or 296 is selected for the finish coat, an intermediate coat of Series 284 is required. Note: Drier mixes, typically used for power trowel application, should be grouted with Series 237 or 238 prior to the finish coat application.
