E903UCB Cove Base Urethane Mortar  

CURE SCHEDULE (@70F)

APPLICATION TEMPERATURE: 40-85 degrees F with relative humidity below 85%

MIXING AND APPLICATION INSTRUCTIONS

PRODUCT STORAGE: Store product in an area so as to bring the material to normal room temperature before using. Continuous storage should be between 60 and 90 degree F. Keep from freezing.

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 or blended into an applied epoxy floor overlay. All large cracks should be V cut and filled with appropriate crack filler. All expansion joints should be filled with 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 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.

PRIMING: No primer is necessary. This material is self-priming. However, any suitable primer can be used.  Can use the liquid only NP1 as a primer to aid in application.  In some applications, primers such as our NP162 can be used to aid in application.

PRODUCT MIXING: This product is packaged in pre-measured kits. Use the entire kit – do not modify. Pour the part A into a five gallon mixing vessel and add one bag of the powder pigment to the part A and mix about 15 seconds using a 1/2″ drill and jiffy type mixing paddle. With the mixer running, pour the part A into the mixing pail. Add the powder pigment bag to the part A liquid and mix for about 15 seconds. Add the part B liquids and mix again for another 15 seconds. Gradually, add all of the contents of the supplied filler part C into the liquid mixture and blend thoroughly until all particles are wetted out, normally about two minutes. Improper mixing may result in product failure. Make sure to apply the product immediately after it is completely mixed. For best mixing results and proper blending of parts A and B, recommend a Jiffy Mixer style drill mixer.

Use of an improper drill mixer can result in streaking of the color because the pigment has not been thoroughly blended.  It can also create curing problems if the hardener also called activator (Part B) is not thoroughly blended with the resin (Part A) which can cause some areas on your floor to remain soft and not harden properly.  DO NOT USE A PAINT MIXER.  Many mixing problems described above can be traced back to using a paint mixer..  DO NOT HAND MIX as this approach can also result in the same problems as using a paint mixer.

PRODUCT APPLICATION: (see application video) Apply the mixed material using a marginal trowel, cove base trowel or any other suitable application equipment at a minimum 1/8 inch thickness. 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.   Lay abutting edges within 10 minutes to ensure a clean edge. A “wet edge” installation is imperative during large applications to avoid lines and ridges in the finished cove base.

RECOAT OR TOPCOATING:  Topcoats are optional dependent on desired results. In some areas, a suitable novolac or other types of coatings can be used, depending on specific requirements.

SURFACE 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 surface to light duty and non-harsh chemicals until the coating is fully cured (see technical data under full cure). It is best to let the surface 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

• Colors or clarity for clear may be affected by high humidity, low temperatures, or chemical exposure.
• For best results use a high quality 1/4” nap roller.
• Color or gloss may be affected by environmental conditions like humidity, temperatures, chemicals, or exposure to lighting such as sodium vapor lights.
• Mortar Colors are different from colors used for other epoxies.  Colors may vary from batch to batch due variations in the silica filler.
• For chemical exposure areas, we recommend a suitable topcoat to reduce porosity and chemical migration.
• Substrate temperature must be 5°F above dew point.
• All new concrete must be cured for at least 30 days.
• Apply a suitable primer before using this product.
• Physical properties are typical values and not specifications.
