NE256M Acid/Chemical Resistant Mortar Patch

Novolac Epoxy Mortar NE256M is a three component 100% solids epoxy high build mortar designed for applications where splash and spills of acids and chemicals occur including traffic areas, chemical troughs, curbs, tanks, and general chemical spill areas.  

Applied from 1/8″ to 1/4″, NE256M Novalac Epoxy Mortar Patch is suitable for most immersion applications although immersion for some chemicals will not be suitable.

Available in 2 gallon kit (.11 cubic feet), 5 gallon kit (.44 cubic feet) and bulk kit (2.2 cubic feet)

 
PRIMER: None required.
TOPCOAT: None required (when applying NE256M in severe chemical exposure areas, topcoat with liquid portion of kit or suitable topcoat or grout coat to prevent chemical migration to the substrate.)

 Where is the NE256M used?

  • Chemical process plants
  • Pulp and paper mills
  • Food processing
  • Gas processing

MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material room temperature before using.  Continuous storage should be between 60 and 90 degree F.  Low temperatures or great temperature fluctuations may cause product crystallization.

SURFACE PREPARATION: All dirt, oil, dust, foreign contaminants, and laitance must be removed to assure a trouble free bond to the substrate.  We recommend that an aggressive shot blast be performed prior to the application of this product.  A less adequate method would be acid etching, but the etch should properly profile the substrate.  All edges and around columns or beams should be mechanically scarified.  All termination points should not be feather edged, but should be saw cut with the termination ending at the sawcut.  All large cracks should be V cut and filled with an appropriate crack filler.  All expansion joints should be filled with an appropriate joint filler.  When overlaying an expansion joint, a single saw cut through the epoxy overlay will prevent random fracturing.  A test should be made to determine that the concrete is dry; this can be done by placing a 4’X4’ plastic sheet on the substrate and taping down the edges.  If after 24 hours, the substrate is still dry below the plastic sheet, then the substrate is dry enough to start coating.  The plastic sheet testing is also a good method to determine if any hydrostatic pressure problems exist that may later cause disbonding.

PRODUCT MIXING:  It is important that the liquids be mixed together first.  Mix the liquids in an oversized container thoroughly and until streak free.  After the liquids are thoroughly mixed, add in the aggregate.  Mix in the aggregate with slow speed mixing equipment such as a jiffy mixer or rotating bucket/stationary mixing blade assembly.  It is equally important that enough time is spent mixing in the aggregate to insure that the aggregate is thoroughly wetted out.  No induction time is necessary.

For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

PRIMING:  No primer is necessary.  This material is self-priming.  However, any suitable primer can be used.

PRODUCT APPLICATION: Apply the mixed material at 1/8 to 1/4 inch thickness.  Apply the material with a hand trowel or other suitable application equipment.  Do not over-trowel the material as this may cause isolated blisters to form.  Maintain temperatures within the recommended ranges during the application and curing process.

RECOAT OR TOPCOATING:  No recoating or topcoating is necessary.  However, if you opt to topcoat the applied mortar, allow it to cure before topcoating

CLEANUP: Use xylol.

FLOOR CLEANING: Caution!  Some cleaners may affect the color of the floor installed. Test each cleaner in a small area, utilizing your cleaning technique.  If no ill effects are noted, you can continue to clean with the product and process tested.

RESTRICTIONS: Restrict the use of the floor to light traffic and non-harsh chemicals until the coating is fully cured (see technical data under full cure).  It is best to let the floor remain dry for the full cure cycle. Dependent on actual complete system application, surface may be slippery, especially when wet or contaminated; keep surface clean and dry.

LIMITATIONS:

  • Clarity of color may be affected by environmental conditions such as high humidity, low temperatures, or chemical exposure.  Chemical exposure may cause discoloration.
  • Mortar colors are not from our standard color chart.
  • Colors may vary from batch to batch due to variations in the silica filler.  Use only material from the same batch for an entire job location.
  • Substrate temperature must be 5°F above dew point.
  • All new concrete must be cured for at least 30 days prior to application.
  • Results of use are contingent upon proper application.
  • Test data based on neat resin
  • Physical properties are typical values and not specifications.
