Polymeric Sand Calculator for Pavers

Aspect	Details
Definition	Polymeric sand is a blend of sand and special additives that hardens when wet, creating a solid joint between pavers.
Composition	Typically made from silica sand mixed with polymers; some variations may include Portland cement.
Benefits	- Durability: Resists erosion and washout. - Weed Prevention: Reduces weed growth and insect penetration. - Aesthetic Variety: Available in multiple colors to match or contrast with pavers.
Drawbacks	- Can crack in freeze-thaw cycles. - Not ideal for irregular stones or wide joints. - Risk of staining if not applied correctly.
Ideal Conditions for Use	- Pavers must be dry. - Temperature should be above 32°F during installation. - Avoid heavy rain immediately after application.
Installation Steps	1. Prepare Surface: Remove existing sand and clean paver joints. 2. Spread Sand: Pour sand onto pavers and sweep into joints. 3. Compact Sand: Use a vibratory plate compactor or rubber mallet. 4. Clean Surface: Remove excess sand with a leaf blower. 5. Activate Sand: Lightly water the sand to activate the polymers.
Maintenance Tips	- Regular sweeping to keep joints clean. - Use soap for tough stains; vinegar, salt, and baking soda can also help. - Avoid applying on rainy days or when pavers are wet.
Common Applications	Suitable for patios, walkways, and driveways made of concrete or brick pavers with narrow joints (typically less than 2 inches).

Polymeric sand is a modern solution for filling the gaps between pavers, providing long-lasting results compared to traditional sand options due to its binding properties and resistance to environmental factors.
