Endurable Concrete Sealer™, Matte

APPLICATION INSTRUCTIONS: FOR POLISHED CONCRETE, YOU MUST FOLLOW THE ARCHITECTURAL SPECS AVAILABLE ON THE DROP-DOWN MENU AT ENDURABLEPRODUCTS.COM.

FOR ALL OTHER APPLICATIONS, FOLLOW THE INSTRUCTIONS BELOW.

1. For optimum results, open troweled concrete mechanically.
2. Apply to dry, porous concrete.
3. Mix Component 1 with Component 2, then mix with twice as much water as components.
4. Use a mixing drill and paddle for minimum of 2 minutes.
• Pot life is 45 to 90 minutes on matte and 90 to 180 minutes on gloss.
5. Do not apply 2nd coat until 1st coat is completely dry.
• Product may be applied via pump sprayer with a conical tip - .05 to .15 gpm at 40 psi, airless sprayer, or T-Bar micro-fiber applicator.
• When applying over stain, it is recommended to spray the first coat to avoid movement of color residue.
• Second coat MUST be applied via microfiber T-Bar applicator or low-speed buffer when dealing with smooth surface floors.
• Second coat may be applied via sprayer on most exterior concrete.

PRODUCT SHOULD BE MIXED 1 TO 1 WITH WATER ON SECOND OR SUBSEQUENT COATS WHEN APPLYING OVER NON-POROUS OR SMOOTH SURFACES. DO NOT OVER-APPLY.

Coverage rates are typically between 300 and 500 square feet per gallon per coat on the first coat depending on porosity of surface. Subsequent coats or low porosity surfaces may yield higher coverage rates of 500-800 square feet per gallon.

Before application of sealer, make sure surface is free from dirt, oils, previous sealers, etc. It must be applied in thin coats. Two coats are usually sufficient, but applicator must determine the specific need. Sealer should be applied between 40 and 90 degrees Fahrenheit.

After applying the first coat, wait until the sealer is dry to the touch, usually 45 to 180 minutes for matte, 3-6 hours for gloss, depending on temperature and air flow, and then subsequent coats may be applied. Subsequent coats typically take 3 to 8 hours to dry for matte and 6 to 24 hours for gloss depending on temperature and air flow.

After application, tools may be cleaned using soap and water.

Light traffic is possible after 8-24 hours and heavy traffic is possible after 24-48 hours. The sealer will gain strength over the next few days after application and will reach full cure at 7-10 days. Avoid subjecting the sealer to freezing temperatures or moisture for 12-36 hours after application. Make sure substrate is dry before application.

ENDURABLE CONCRETE STAIN can penetrate product for the first 4 hours after sealer is dry when stain is mixed in water.

ENDURABLE CONCRETE STAIN may penetrate product when mixed in acetone for the first two days after application. If applying stain mixed in acetone over sealer, spray VERY lightly. Too much acetone can “cook” the sealer. Upon further curing, the stain cannot penetrate unless an additional coat of product is applied.

Only ENDURABLE VERTICAL STRIPPER may remove products when sealer is fully cured. This requires the stripper to be covered and remain wet for a minimum of 12 to 24 hours.

SLIP RESISTANCE AND CLEANABILITY: The profile of the concrete will dramatically affect the slip-resistance. Aggressive finishes, such as broom-finished concrete, will yield the best coefficient of friction and will be slightly more challenging to clean. Smooth surfaces will yield a lower coefficient of friction but are easier to clean. If desired, additional slip resistance can be added to the sealer. 100 mesh polypropylene will work well and should be applied in the second coat. It is best to mix it into the sealer and then apply with a T-Bar or the additive can be broadcast into the sealer. When slip-resistant additive is used, it is recommended to mix the sealer 1 to 1 with water to help keep the additive in solution. It is also recommended to apply a third coat of sealer to completely encompass and protect the additive.
