All repairs must be made to the walk prior to applying a sealant. This means the walk must be restored to its original condition and all joints must be filled with polymeric jointing sand before sealing.

Polymeric jointing sand is a high-tech mix of graded, colored sand and a binder, specially formulated for the filling of joints between pavers, slabs or natural stones. Unlike conventional sand it stays in place and remains stable. It softens when wet and firms up when dry to better resist soil movements. Because the sand gets stiff you can expect fewer weeds and less insect damage.

YES. However, all the old sand must be completely removed with a specially equipped power washer. The entire surface must be thoroughly dry before the new polymeric sand can be installed.

NO. Polymeric sand cannot be used to top off joints that already have sand in them. The old sand must be completely removed before applying new poly sand. Polymeric sand needs at least 1.25 inch of depth to cure properly.

YES. Polymeric jointing sand will last longer and give better results, but in older and very large areas of paving where mason sand has been used, an alternative is to top off the joints with additional sand then apply a joint stabilizer. It’s designed to protect the surface while bonding the sand. This stabilizer is effective for a period of two to three years.

It is more important to plan your landscaping for the long term. Although it’s less expensive to build a square patio or small deck, it’s no bargain if you find that later the results so dissatisfying that your family uses it less. It may be worth it to pay for a professional landscape design and own an outdoor living space that you love to use. Check out how you can create a room-like space with retaining walls.
