Polymeric Sand vs Brick Sand: Which Should You Use for Pavers?

Still using brick sand between your pavers? You could be inviting weeds, shifting, and early repairs. Let’s break down why polymeric sand is the smarter, cleaner, long-term choiceand why brick sand just doesn’t cut it for modern paver jobs.

What Is Brick Sand?

Brick sand (also known as masonry sand) is a fine, washed natural sand typically used to mix mortar for laying bricks and blocks. It's great for vertical construction projects or as bedding under pavers.

But when used between pavers?

It can wash out, attract weeds, and shift over timenot ideal for joint stabilization.

What Is Polymeric Sand?

Polymeric sand is a specialized jointing material made from fine sand mixed with polymer binders. Once activated with water, it hardens in the joints, locking pavers in place and preventing movement.

It’s engineered specifically for hardscape installations, and it shows.

Quick Comparison: Brick Sand vs. Polymeric Sand

Brick Sand:

• Made of washed natural sand

• Doesn’t harden on its own

• Easily washes or blows out

• Attracts weeds and ants

• Needs frequent refilling

• Great for mixing mortar, not paver joints

Polymeric Sand:

• Contains binders that activate with water

• Harden to lock joints in place

• Resists erosion, weeds, and pests

• Low-maintenance and long-lasting

• Designed specifically for horizontal paver joints

Why Is Polymeric Sand the Better Choice?

If you're working with interlocking pavers, porcelain, or natural stone, polymeric sand gives you unbeatable advantages:

Stops weeds, ants, and shifting
Longer-lasting joints — no constant refilling
Cleaner finish with haze-free options
Quick curing and weather resistance

Meanwhile, brick sand was never meant for this job. It doesn’t bind, and once it’s wet and dry a few times, it can disappear completely, taking your stable surface with it.

Our Pro Recommendation

For any horizontal paver project, polymeric sand is hands-down the better choice. It saves you time, maintenance, and stress — and keeps your patio looking flawless.

No more messy joints. No more refills. Just a rock-solid patio that lasts.

Frequently Asked Questions — Because We Know You Have Questions!

Q: Can I use brick sand between pavers?
A: Technically, yes — but it’s not recommended. Brick sand doesn’t harden or lock in place. It can easily wash out, shift, or allow weeds to grow between joints.

Q: Why is polymeric sand better for paver joints?
A: Polymeric sand contains binders that harden with water, forming a durable, weed-resistant joint that resists erosion and keeps your patio looking clean with minimal upkeep.

Q: Is polymeric sand more expensive than brick sand?
A: Yes, the upfront cost is higher, but you’ll save in the long run with fewer repairs, less maintenance, and longer-lasting results.

Q: What happens if I use brick sand first and want to switch to polymeric sand later?
A: You’ll need to remove as much of the old sand as possible. Polymeric sand needs clean, dry, debris-free joints to bond properly.

Q: Does polymeric sand work with natural stone or porcelain pavers?
A: Yes! Just use a haze-free formula and sweep thoroughly before wetting. It’s safe for concrete, porcelain, and natural stone.

Q: Can I use polymeric sand for vertical joints like brick walls?
A: No. Polymeric sand is only for horizontal surfaces like patios and walkways. For vertical joints, use traditional mortar with brick sand.

Q: Do I need to reapply polymeric sand over time?
A: Not often. High-quality polymeric sands can last 5–10 years or more, depending on traffic and conditions.
