How to Mix Rubber Chips & Adhesive
Rubber floor surfaces have always been soft enough to cushion a fall while being sturdy enough to withstand every day wear and tear even in heavily trafficked areas. However, covering a large area with a layer of solid rubber material thick enough to serve as everyday flooring can be expensive. Using rubber chips mixed with an adhesive allows you to utilize recycled rubber to create a flooring surface of equal utility as a solid rubber surface, at a fraction of the cost. You can mix the rubber with the adhesive on site. It's just a matter of combining the rubber with enough adhesive to bind it into a solid mass.
Pour the rubber chips that you intend to use as your flooring into a rotating tumbler. Check the bags of chips for chip weight when adding the chips so you can keep track of the total amount of chips by weight that you've placed into the tumbler.
Turn the tumbler on to begin rotating the barrel.
Pour the adhesive into the tumbler as it rotates in order to cover the rubber chips completely with the glue. Add the adhesive by weight pouring in at least 18 percent of the total weight of the rubber up to 22 percent of the total weight of the rubber. Determine the amount to add by multiplying the weight of the rubber used that you took note of earlier by .18 to get the 18 percent amount. The weight of the adhesive is listed on each adhesive container and most paving jobs will require multiple containers to complete. Add containers until you reach the total weight amount. Add slightly more, up to the 22 percent amount, if the chips aren't completely covered by adhesive.
Continue to roll the rubber and the adhesive within the tumbler until you have full coverage of the rubber chips in the adhesive. Once you've covered the chips completely, you can pour the mixture onto your targeted area and spread the mixture where needed using a trowel.
