Endurable masonry sealer is a product designed to provide a protective waterproof seal on surfaces coated with cement veneers or MicroToppings. MicroToppings are commonly applied on floors but can be utilized on other surfaces that need a continuous seamless coating, such as showers (both walk in and cabins), kitchen counters, fireplace walls with gas inserts and other area’s.

Endurable masonry sealer is versatile and can be used for both residential or commercial applications. It is a heavy duty product with strong bonding properties, making it great for forklift traffic & parking garages. Can be applied via sprayer, T-Bar Microfiber applicator, or other roller.

The low VOC content means it is safe for residential use and even for kitchen countertops or commercial food preparation areas. It has excellent UV stability (will not yellow or degrade in sunlight) and high resistance to chemicals and solvents. This provides anti-graffiti qualities and resistance to hot tire pickup.

Sizes: 1, 4.5 gallon containers
Samples: 12oz covers 30 to 80 sq ft by coat
Spread Rate: 300 to 800 sq ft per gallon


Endurable masonry sealer must be applied in thin coats. Two coats are usually sufficient, but the applicator must take into consideration the specific needs of each project. This sealer should be applied between temperatures of 5 to 32 degrees Celsius (40 to 90 degrees Fahrenheit). The product has low odor during application.

Diluting Endurable Masonry Sealer with Water

FIRST COAT: On any porous surface, dilute 2 PARTS SEALER TO 1 PART WATER.

NOTE: When applying over non-porous, smooth surfaces, use the dilution ratio of the second coat, 1 PART SEALER TO 1 PART WATER.

Step by Step Endurable Masonry Sealer Application

Apply 1st coat with a ¼” microfiber roller or T-Bar microfiber applicator.

Do NOT apply 2nd coat until 1st coat is completely dry. The 2nd coat may be also applied with a Microfiber Roller-TBar applicator, or sprayer. Make sure the substrate is dry before application and at a ph. level of not more than 10.

After applying the 1st coat, wait until it is dry to the touch;

  • Usually 1 to 2 hours for matte,
  • 2 to 3 hours for gloss,

[depending on temperature and air flow, and then subsequent coats may be applied.]

Subsequent coats typically dry times;

  • 3 – 8 hours for matte
  • 6 – 24 hours for gloss

[depending on temperature and air flow.]

The pot life once mixed if kept cold and covered is 2/3 hours. If you break down the undiluted gallon kit for example, to use for first and second coats at varied dilution ratios, it will store well for 2 to 3 days in a cold place if the lids are tight, but it MUST BE STRAINED before subsequent coats are applied.

The maximum recoat windows are;

  • 3 to 4 days or less for matte
  • 5 to 7 days for gloss.

After these windows it will be necessary to scuff the surface to maintain mechanical bond. Be very careful to measure accurately, as well as shaking the bottles well prior to application.

  • Once the surface has turned milky white, stop applying additional product.
  • On textured concrete, the sealer might settle into the lower impressions of the surface. If this happens, use a rag or cloth to blot the area so the sealer will cure properly. Do not apply more than 4 mils per coat or the product will not cure out properly.
  • After sealer turns clear, direct or forced air across the surface can substantially speed the drying process, especially at higher temperatures. Lower temperatures will slow the drying process.

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

  • Light traffic is possible after 8 to 24 hours
  • Heavy traffic is possible after 24 to 48 hours

The sealer will gain strength over the next few days after application and the MicroTopping will reach full cure in 7 to 10 days.
