Joint Sand for Block Paving: Cement-Sand Mix Essentials

Yes, you must mix cement with sand for brushing into paver joints. Here's why and how.

Why Cement-Sand Mix

• Dry cement doesn't stain pavers during application
• Sets hard with ambient humidity or light rain
• Locks pavers against movement
• Resists washout better than plain sand

Mix Ratio

Typical: 1 part cement : 3-4 parts sand (by volume). Mix dry, brush in, compact, mist lightly.

Application Tips

• Work in dry conditions
• Ensure joints are clean and dry
• Brush thoroughly into joints
• Plate compact after filling
• Light mist to activate cement (don't flood)

Result

Firm, stable joints that resist weeds, ants, and erosion—far superior to plain sand for longevity.
