Surfacer/Filler/Patcher
Series 215, 217, 252SC ChemBloc (MCK) mortar. Note: The following products can be used as a surfacer, filler, or patcher by mixing with 211-9111 Bulking Additive: Series 120-5002, 251SC, 1402, 1407, 1415, 1416, and 1418. Note: A repair kit of 201, with Part C fumed silica, is available for small patching/surfacing repairs (reference Technical Bulletin 99-22). For more extensive repairs and additional information, contact your Tnemec representative or Tnemec Technical Services.
Volatile Organic Compounds
Unthinned: 0.2 lbs/gallon (23 grams/litre)
Topcoats
Series 252SC. Note: A saturant coat of 252SC liquids is required over fiberglass mat prior to application of topcoat. However, when Series 206SC flexible basecoat is used, then a 237SC or 239SC saturant coat is required.
Curing Time
| Temperature | To Topcoat | Place in Service | Full Cure |
|---|---|---|---|
| 75°F (24°C) | 6 to 72 hours | 24 hours | 72 hours |
If more than 72 hours have elapsed between coats, the ChemBloc coated surface must be mechanically abraded before topcoating. Note: A 24 hour cure provides for traffic, secondary containment and certain mild chemical exposures. Contact your Tnemec representative or Tnemec Technical Services.
