Product Description:

TAMTECHseal is a high performance product designed to harden and consolidate sand in joints and seal the surface of pavers, bricks and concrete. This waterbased polymer will stabilize the joints, prevent wash-out of the sand and help stop weeds from growing through the joints. The product also acts as a clear sealer with a gloss finish to help protect against the weather, water, dirt, freeze thaw damage and staining. TAMTECHseal can be applied right after the installation of the pavers and has no odor, is safe to use and cleans up easily with water. The sealer is breathable, thus moisture is not trapped in the pavers. It is an exterior and interior product that can be used on new or old pavers, bricks or concrete.

Features & Benefits:

  • Prevents sand washout and joint deterioration

Pavers, bricks or concrete must be clean and dry. Remove all dirt, efflorescence, oil and loose debris. A leaf  blower is recommended to remove the dust and debris.  Sweep dry, properly graded sand into joints and fill to required level slightly below the top of the pavers. (typically 1/8") Completely remove all remaining sand from the top of the pavers. Apply product with a pump-up sprayer, low pressure spray equipment about 15-20 psi or a roller. Apply a flood coat to the paver surface including the joints. While surface is still wet, push excess material from the surface of the pavers into the joints using a foam squeegee.  Do not leave excess or pooled material on the surface of the pavers. On vertical surfaces, brush out any run downs. Product is white but will dry clear to the touch in typically 30-45 minutes depending on temperature. Keep water and traffic off for 24 hours.

Concrete & clay pavers: 75-150 sq ft /gal
Bricks:  100-200 sq ft /gal, Concrete: 150-200 sq ft/gal

Coverage rate will depend on texture and porosity of the surface. Porous concrete pavers may need more than one coat to develop the gloss finish.


Do not leave excess or pooled material on the surface of the pavers. Do not apply product to a damp surface. Always do a small test to ensure desired look and performance of the sealer. Do not use on very smooth or polished stone and granite, slate or bluestone. The minimum application temperature is 45 degrees F for 20 hours before and after the application. In hot, 90 degree F weather, working time is reduced so apply the product in the cooler morning hours. Do not apply if rain is expected within 12 hours. In case of rain, wait until surface is completely dry before continuing.

Two years in unopened containers. Do not allow stored product to freeze since it is water based.
