Joint Hardener For Paver Sand & Paver Sealer – With Fungicides!

 (We do ship orders from our local distributor.)

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. Fungicides were added to resist moss, mold, etc. 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, so 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.

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 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.
