We recommend always ordering extra product to account for overages, spillage, and touch-ups. In most cases, unused unopened product can be returned. When in doubt, round up.

PolymerSandStore.com is not responsible for product shortages or overages resulting from the use of this calculator. Always refer to the manufacturer technical data sheet and consult with a professional installer if you are unsure about quantities.

Resin Jointing Sand Questions and Answers

What is resin jointing sand?

Resin jointing sand is a pre-mixed, brush-in joint compound made of graded sand coated with resin binders. Unlike traditional polymeric sand, most resin formulas come ready to use in a sealed pail, and many cure through air exposure alone with no water activation needed. The result is a firm but flexible joint that resists weeds, ants and washout.

What is the difference between resin jointing sand and polymeric sand?

Polymeric sand is a dry mix you sweep into the joints and activate with water, while resin jointing sand comes pre-activated or air-curing in a sealed pail, so weather is far less of a factor. Resin sand costs more per square foot but is more forgiving on porcelain and in damp climates. For standard concrete pavers with a dry forecast, polymeric sand is usually the budget-friendly pick.

Can you install resin jointing sand in the rain?

Many resin sands tolerate damp conditions, and air-cured formulas like Gator Nitro-X can go down rain or shine, which is a major advantage over polymeric sand and its required 24 hour dry window. Water-activated resin products still need their watering step, so check the preparation notes for your product above.

How much does a pail of resin jointing sand cover?

Coverage depends on joint width, joint depth and paver size. A 27.5 lb pail goes furthest on large-format pavers or porcelain with narrow joints, while small pavers and wide joints use far more material. Select your product in Step 1 and this calculator applies the manufacturer published coverage rates to your exact dimensions.

Is resin jointing sand permeable?

Most resin jointing sands are permeable, meaning the cured joint lets rainwater drain through instead of sealing the surface. That helps prevent puddling and makes products like SRW WetLok a natural fit for permeable paver systems. Check the description for your specific formula.

Does resin sand work on porcelain pavers?

Yes, resin jointing sand is one of the most popular choices for porcelain tile and slabs because it avoids the polymer haze that standard jointing sands can leave on dense, non-porous surfaces. Use the porcelain surface option in Step 2 for accurate coverage numbers.

How long does resin jointing sand take to cure?

Most resin joints accept light foot traffic within about 24 hours, while vehicle traffic can require 5 to 7 days and full cure up to 28 days depending on the product, temperature and humidity. See the preparation and installation notes for your product above for exact times.

Does resin jointing sand stop weeds and ants?

Yes. The resin binds the sand into a firm joint that leaves no loose material for ants to nest in and little room for weed seeds to root. Seeds that blow onto the surface can still sprout on top of the joint, so an occasional sweep keeps things clean.

Can you save leftover resin jointing sand?

Often, yes. Some products reseal in their pail while others are stored covered with a couple of inches of water, with shelf life commonly around 18 months. Check the storage note for your product above, and remember unopened pails can usually be returned.

Do you need to seal pavers after using resin jointing sand?

No, sealing is optional since the resin joint is already bound and water resistant on its own. If you do want to seal the pavers for color enhancement or stain protection, most manufacturers recommend waiting about 30 days after installation.
