More details

Dura Seal 400

Porous concrete floors or floors that experience a lot of traffic, whether pedestrian or vehicular, need the protection that Dura Seal 400 offers. Dura Seal 400 penetrates into the pores of the concrete for excellent adhesion and “lies on top” to form a solid surface plate, recognized by the USDA as a contaminant barrier.

In addition to black, white, and clear, Dura Seal 400 comes in a wide variety of floor colors. Also choose from a wide selection of colors of plastic chips which may be sprinkled within the coating to provide an endless variety of colors and textures.

Dura Seal 400 meets all USDA and EPA standards. Applied by roller, brush, or spray, it leaves an easy-to-clean, hard, glossy floor surface, suitable for incidental food contact. Available in 10 gallon or 2 gallon units and mixes 1:1.

The Dura Seal 400 promise

Dura Seal 400 epoxy gives your floor — whether it be in an automotive show room or service area or a plastics or printing shop — the clean, neat, organized look that impresses customers.

Dura Seal 400 provides floors with heavy-duty protection from wear. It prevents dusting of concrete, makes floors wear longer, protects floors from penetration of oil, grease, and foreign matter, mechanically hardens the concrete by filling the pores and binding the particles, and provides a hard, yet elastic, durable, damage-resistant surface.

There is no higher quality floor seal available on the market today. Northwest Airlines is still using a Durall floor laid down 33 years ago!

Applying Dura Seal 400 is simple and concrete preparation is the key to long life and over-all lower costs.

Scrub with carbide nilo grit type brush and rotary scrubber. Then vacuum off and do as follows:

  1. Apply Degrease Rite, a pH 12 degreaser
  2. Apply Dura Kleen Etcher, a pH 5 cleaner.
  3. Water rinse twice.
  4. Allow to dry to white finish.
  5. When surface is rough and clean to touch (no dust), apply with roller, brush, or airless sprayer (use vapor mask).
  6. After 6 hours, repeat step 5. as needed.
  7. Drivable in 12 hours, cures over 28 days.

Timing per 1,000 sq. ft. of above:

  1. 1.5 hours
  2. 1.5 hours
  3. 1.0 hours
  4. 5.0 hours
  5. 0.5 hours
  6. 0.5 hours

Dura Seal 400 Colors

Customers like Cessna Citation use a colored circle to position the location of each plane on their manufacturing floor. Others color their entire walk ways with our OSHA Yellow in order to avoid placing items in the aisles. Durall can also help you add pizzazz to your floor. Durable color formulations are as dependable as plain old gray—so live a little! Eliminate dangerously slippery surfaces with the addition of non-skid additives, or choose high gloss for a stunning mirror sheen.
