Frequently Asked Questions

Thick enough to trowel, but thin enough to ensure all the sand is saturated. Too much sand will not allow the Spall material to wet around and bond the sand together and to the substrate.

Usually this is caused by being off ratio. When using the SB2005, we recommend you to monitor the products to be sure nothing has caused it to pump off ratio. Check the level in the tanks regularly. Always be sure to dispense a small amount of mixed material off to the side when beginning to ensure the product is on ratio.

We manufacture the pumps at our facility in Rancho Cucamonga, California. The pump comes standard to run off an extension cord. Optional battery/inverter set ups are available, along with larger tanks, heat belts, low pressure spray rigging, low viscosity set ups, custom frame colors, modified gear ratios for material that is not 1:1 ratio, etc…

The SB2005 was designed to pump our polyurea and Spall repair products but many other polyureas have been, and can be, pumped as well. Please contact our office regarding the product you are considering.

There was excessive moisture present either in the aggregate added to the Spall material or in the substrate being repaired. You can sand the cured Spall repair flush with the surface, however, it is best to minimize moisture before use.

Yes, but the product is aromatic so the UV rays from the sun will tinge it a shade of green. Therefore, you should only use it outside if there is not an aesthetic concern or if you are going to cover it with a coating, paint, or stain.

Any grade will work up to pea gravel - 30 is the most common size used. A good practice is a mixture of different grades. The most important issue is minimal moisture content.

If it is in stock, we will ship it within 24 hours. If we are out of stock, it could take 3 – 4 weeks.

Polyurea has an endless amount of uses. The joint filling of concrete floors has proven to be one of the best products available for this application. When sprayed or rolled, polyurea can be used to coat floor to wall junctions in cold storage facilities as well as freezers, coating of floors, decks, patios, roofs, tank liners, manhole liners, bed liners, vault encapsulation, sports courts, pools, ponds, fountains, fish hold tanks, dock coatings, undercoating of vehicles, etc… Just about any system requiring a monolithic seal with high impact and abrasion resistance can be enhanced by using polyurea.

One gallon will fill approximately 100’ in a typical joint at ¾” depth in a new warehouse floor. This includes the amount of overflow that is shaved off after the polyurea cures. A 22 oz, cartridge typically will fill 15’ of a standard floor joint. Please see volume charts for exact calculations.

It is off ratio. When using a machine to pump the polyurea, it is necessary to make sure nothing has caused it to pump off ratio. Monitor the level in the tanks regularly. Hand dispensing needs to be done with consistent smooth pressure. Always be sure to dispense a small amount off to the side when beginning to ensure the product is on ratio before installing in a floor joint.

Yes, many companies polish and coat over our polyurea with great results.

The “B” side must always be mixed/stirred before use. This re-blends the chemicals and pigments to ensure the product will be on-ratio and uniform in color. Warming the polyurea to approximately 70° helps keep the material in a nice flowable state. The colder the product, the thicker it seems; likewise, warmer material will be thinner.

The standard color is concrete grey. Many color formulas have been made and are on file for certain food chain stores and warehouses including safety yellow, mocha brown, black, etc… Therefore, color matching is an option with minimum orders of 10 gallons.

You can walk/drive over it within minutes, however, you should wait at least one to two hours before shaving it flush with the floor.

1 gallon equals 128 ounces, which also equals 231 cubic inches. Therefore, figure the approximate cubic inches, and convert that to ounces. When dry silica sand is added to the product, you can increase your total volume by 150%. Example, 2 gallons of Spall material + 2 gallons of dry silica sand = approximately 3 gallons of mixed material. Please see volume charts for exact calculations.
