Surface Preparation
Surfaces to be coated must be primed prior to application of SPARTACOTE Epoxy Membrane. Ensure that proper re-coat windows are observed. See applicable primer technical data sheet for surface preparation requirements.
Compatible SPARTACOTE Primers:
- SPARTACOTE General Primer (DS 622.6)
- SPARTACOTE Oil Tolerant Primer (DS 622.9)
- SPARTACOTE WB Epoxy Primer (DS 085.8)
- LATICRETE® VAPOR BAN™ ER (DS 35216.0)
- SPARTACOTE Moisture Vapor Barrier (DS 087.5)
Substrate defects (voids, bugholes, divots, etc.) should be filled smooth with surrounding substrate surface with SPARTACOTE Epoxy Fill Coat (see technical data sheet DS 623.3 for application instructions) prior to the application of SPARTACOTE Epoxy Membrane.
Mixing
SPARTACOTE Epoxy Membrane is provided in premeasured units and when mixed will yield 5 gal (18.9 L) of material. Prior to mixing, mechanically mix Part A separately for 1- 2 minutes to disperse any fillers which may have settled. Mix pre-measured unit of Part A with pre-measured unit of Part B for 2-3 minutes. Pour mix directly onto the primed concrete.
Application
SPARTACOTE Epoxy Membrane may be applied by notched squeegee or SPARTACOTE resin broom. Suggested application thickness is 20-30 mils (0.5-0.8 mm). Spread evenly over all primed surfaces and immediately backroll with a spiked roller to deaerate and help level.
To aid in inter-coat adhesion, it is recommended to lightly buff and acetone wipe the surface prior to recoating. A light broadcasting of 30 mesh kiln dried sand into the wet SPARTACOTE Epoxy Membrane may also be used to enhance adhesion of subsequent coats. Appropriate recoat times must be observed. Exposure of the coating to direct sunlight will considerably shorten the recoat times. If recommended recoat times are exceeded, consult a LATICRETE Technical Service Representative; sanding or abrasive blasting may be required. For vertical applications, SPARTACOTE Epoxy Membrane may be applied by roller. Spread evenly over all primed surfaces. Two coats may be necessary to achieve a 20-30 mils (0.5-0.8 mm) total thickness.
SPARTACOTE Epoxy Membrane is designed to be used as an underlayment in SPARTACOTE resinous coating systems. It is not recommended as a standalone product. Consult a LATICRETE Technical Service Representative for best options. With all epoxies after priming and before each additional coat, examine the surface for amine blush (oily film). If present, remove by cleaning the surface with acetone.
Notes
Mock-ups and field test areas are required in order to validate performance and appearance related characteristics (including but not limited to color, inherent surface variations, wear, anti dusting, abrasion resistance, chemical resistance, stain resistance, coefficient of friction, etc.) to ensure system performance as specified for the intended use, and to determine approval of the coating system. Variability in job site conditions (including but not limited to surface preparation, sunlight, humidity, dew point, temperature, etc.) during application of SPARTACOTE products may lead to fisheyes, blistering, pinholes, wrinkling, or outgassing of air in the concrete and are not product defects. Double priming, shading or evening application may be required.
Cleaning
Use acetone or xylene to clean tools and equipment- Maintenance
The long term performance, appearance, and life expectancy of wear surface products are critically dependent upon a good routine maintenance programdesigned specifically for the installed wear surface. SPARTACOTE floor coating systems are nonporous, causing dirt and contaminants to remain on the surface. The use of properly placed walk-off mats, inside and outside, will help increase the life of the floor. Recommend maintenance program consist of frequent and thorough cleaning utilizing a neutral pH cleaner. The frequency of washing will vary depending on floor usage type, traffic, and age.
