Product Description (Joint Stabilizer / Hardener & Paver Sealer):

Joint Stabilizer / Hardener & Paver Sealer is a high performance product designed to harden and consolidate sand in joints and seal the surface of pavers, bricks and concrete. This water based 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 to help protect against the weather, water, dirt, freeze thaw damage and staining. Joint Hardener & Paver Sealer 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. Do not mix product prior to application. Apply product with a pump-up sprayer or use low pressure spray equipment, about 15-20 psi. Apply a flood coat to the paver surface including the joints. While surface is still wet, use a foam squeegee and push excess material from the surface of the pavers into the joints. Do not leave excess or pooled material on the surface of the pavers. Product is white but will dry clear to the touch in typically 30-45 minutes depending on temperature. Keep light foot traffic off for 4-6 hours and keep water and heavy traffic off for 24 hours.

Concrete & clay pavers: 75-150 sq ft /gal
Bricks:  150-200 sq ft /gal, Concrete: 150-200 sq ft/gal
Coverage rate will depend on texture and porosity of the surface.


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 (7 degrees C) 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. Surface may slightly darken during excessive applications depending upon porosity of the pavers and the application rate.
Note: sealer can be removed with a high pressure, hot water blaster above 200 degrees F or a good paint stripper.

Shelf Life:

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