LTX-100 | High-Flow Epoxy Floor Coating Kit (3 Gal) | 100% Solids, 18,400 PSI

A 3 gallon kit covers 150 to 481 square feet depending on the build you place. At a 16 mil standard build it runs about 301 square feet, at 20 mils for a metallic pour about 241 square feet, and at the 32 mil maximum single pass about 150 square feet. Because LTX-100 is 100 percent solids there is no carrier to evaporate, so applied thickness and cured thickness are the same number and coverage stays predictable. Deduct for profile, porosity and waste, and add 10 to 20 percent on open or freshly shot blasted concrete.

18,400 psi in compression under ASTM D-695, 14,430 psi flexural under ASTM D-790 and 8,400 psi tensile under ASTM D-638, with 80 Shore D hardness and 28 mg loss on Taber abrasion. Adhesion to prepared concrete measures 290 psi under ISO 4624, which is at or above the pull off capacity of sound concrete, so on a correctly profiled slab a bond failure happens in the concrete rather than at the coating line. Tensile elongation of 2.4 percent leaves enough give to absorb normal slab movement.

Pot life in the pail is 20 minutes at 68 degrees F, 40 minutes at 41 degrees F and 10 minutes at 86 degrees F. Dry to touch is about 5 hours at 68 degrees F and light foot traffic returns at about 16 hours. Heavy traffic and vehicle loading at 3 days, full chemical cure at 7 days. Epoxy cure is exothermic, so a full 3 gallon mix heats itself and will accelerate well past those figures if it stands in the bucket. Get it onto the floor immediately after mixing.

Yes, it is built for both. The low mixed viscosity gives a metallic pour the long open flow it needs to develop pigment movement before set, and it carries a full refusal flake or quartz broadcast without starving the bond coat. For metallics, place at around 20 mils. For flake, use it as the bond coat at about 16 mils, broadcast into the wet film, and stay off the surface until it is dry through.

Not on its own. Like all epoxies it will amber under prolonged UV exposure. For exterior work, sunlit interiors or anywhere colour stability matters, protect it with a UV stable pigmented coating or an aliphatic urethane or polyaspartic topcoat.

Concrete cured at least 28 days, diamond ground or shot blasted to an ICRI CSP 2 to CSP 3 profile, moisture content below 6 percent, below 85 percent internal relative humidity when tested to ASTM F2170 and below 3 lb per 1,000 sq ft per 24 hours when tested to ASTM F1869. The slab must be free of oil, grease, curing compound, laitance and dust. Repair and detail cracks and joints before coating, because slab movement telegraphs through a finished system.

Only if the slab fails the moisture tests. If vapor emission or internal humidity exceeds the limits above, install a dedicated moisture vapor barrier primer and let it cure before placing LTX-100. Coating over an active vapor drive is the most common cause of osmotic blistering and delamination on an otherwise sound floor.

2 parts A to 1 part B by volume. You can mix a partial batch as long as you measure by volume rather than by eye, because off ratio material will not reach full cure and cannot be corrected afterward. Pre-mix Part A on its own for a minute, combine in a clean vessel, then mix for a full 3 minutes with a stir stick or a low speed drill and paddle, scraping the sides and bottom of the pail at least twice. Unmixed material clinging to the wall is the usual source of soft spots.

Yes. The base is clear and tintable. Add pigment to Part A only and disperse it completely before Part B goes in. Latux metallic pigment pods are pre-measured for a full 3 gallon kit.

Both are 100 percent solids two component epoxy floor coatings, and both self level. LTX-100 is the higher specification of the two: 18,400 psi compressive against 6,200 psi for EF-100, and under 30 g/L VOC against under 50 g/L. Choose LTX-100 where load, abrasion and long term durability drive the decision, or where a metallic pour needs a long open flow. EF-100 remains the value workhorse for straightforward garage and shop floors.

Chemical splash goggles, chemical resistant gloves in nitrile or butyl rubber, and skin covering protection. Natural rubber latex is not suitable, because epoxy resins penetrate it. Part B is corrosive and causes severe skin burns and eye damage, so add a face shield when handling it and keep an eyewash station and safety shower in the work area. Ventilate during application and cure. Read both Safety Data Sheets before you open a kit.

Shelf life is 12 months from the date of manufacture in unopened containers. Store between 41 and 95 degrees F in a dry, well ventilated area out of direct sunlight, with containers tightly closed and in their original packaging. Protect from freezing. Batch dating is printed on the container.
