ROMPOX ECO-FINE Ready-Mixed Sand & Resin Joint Mortar: Triple Strength Formula for Narrow & Wide Joints, Porcelain, Pavers & Natural Stone. Pressure Washer Safe
Discover ROMPOX - EcoFine, resin-sand mortar designed for lasting, permeable joints. Packaged in a sealed bag, it activates upon air exposure and solidifies into durable, robust joints. Its easy application makes it ideal for both professionals and DIY enthusiasts.
Perfect for patios, pathways, and pedestrian areas, EcoFine requires installation on non-settling, water-permeable bedding or an open-graded aggregate base for optimal performance. Properly securing stones or pavers prevents shifting or fracturing.
With a resin film-free finish, EcoFine is perfect for delicate surfaces like porcelain and ceramic, yet equally suitable for natural stone, brick, and other pavers. Its triple resin content ensures durability in saltwater and chlorine pool environments.
Minimal maintenance is required—just an annual power wash. Submerge unused material in water to prevent curing, allowing storage for up to three months. Choose ROMPOX - EcoFine for reliable, sustainable outdoor projects.
Do It Yourself - DIY
Why pay a contract to fill or repair the joints in your patio or walkway when you can do it yourself? Dump the pre-mixed compound onto the surface and squeegee it into place.
This product is a professional contractor-grade solution that delivers outstanding results when site requirements are diligently adhered to. It is crucial to install it on permeable bedding, ensuring joints of a minimum depth of .75 inches, and securely placing pavers that remain immovable. Reviews indicating product failure are primarily due to inadequate site preparation and incorrect installation practices.

Much stronger and easier to apply than polymeric sand. Worth the higher price. Definitely recommend

I saw this product on Instagram and gave it a shot. I bought 2 boxes and loved it. Worked great! Looks great! Bought 4 more boxes and got the same result! Started a different project and bought 4 more boxes and the first 3 boxes were the same. My last box was clumpy. I went to their website and reached out and to my surprise got a quick reply from customer service. A replacement box was sent the next day and it worked perfect. Great product! Great Service!

This seems to have worked very well. Was a little disappointed in the color. Thought it would be more gray than it was but overall it turned out fine once we sealed it. Very expensive but if it lasts it’ll be worth it.

ROMPOX costs more than polymeric sand, but it performs a lot better. I used ROMPOX to fill in joints around large pavers. It's easy to apply and sets up nicely. The resin joint mortar surface, after hardening, is also water permeable.In the past, I tried polymeric sand, but it starts to loosen up on the surface, cracks, and can be easily etched.

I absolutely LOVE this product. I wanted to fill in cracks between flagstone where weeds and grass were growing and felt overwhelmed when looking at all of the product options until I found this one. I was worried about getting the consistency right with other products and loved that this comes ready to use. I contacted the company and paid for a sample to be shipped to my home to make sure I liked the color and to see how easy it was to use. It really was as easy as all the videos showed. I wet the flagstone, applied the product, smoothed it out, let it dry, washed off the excess and with in a day it could be walked on. I’ve used it in my garden, green house, a path to my storm shelter and plan to use it on 2 other pathways on my property. Yes, it’s a little more expensive than other products but it’s worth it!
