Frequently Asked Questions
LCR is LIQUID CONCRETE REPAIR which is a two-component, 100% solids epoxy resin repair system packaged in a single-use 10 ounce cartridge that is easily dispensed with any ordinary caulking gun!
What are some of the uses for LCR?
Typical uses are repair of cracked concrete such as floors, driveways, and pavements. Cracked and leaking foundations. Restoration and bonding of wood, fiberglass, metal, and masonry materials. Anchoring and securing of railings, posts, and fasteners. LCR can be used to stop water, air, and radon seepage.
What color is LCR?
LCR is clear with a slight amber tint. An LCR repair will have a ‘wet’ look much like a varnish. Sprinkling a ‘like’ material such as sand on concrete or saw dust on wood to the uncured LCR can provide a more finished look.
How fast does LCR harden?
Once properly mixed, LCR has a working time of 30 minutes, will harden in 6-8 hours and achieve full bond strength in 24 hours.
What is Epoxy?
Epoxies are basically high-strength plastics. There are literally thousands of formulations used for everything from artificial trees in a zoo to gluing heat shields on the space shuttle. Epoxies consist of a resin and a hardener which when mixed together causes the two materials to react and harden.
How long will an LCR repair last?
Permanently! Used properly, an LCR repair can be a permanent repair, which will meet or even exceed the original life expectancy of the item repaired.
Can I sand or paint LCR?
Yes.
What will LCR not repair?
Glass, plastic and smooth or polished surfaces. LCR should not be used in expansion joints or during cold weather or when surface moisture is present.
