Is this plank waterproof all the way through?

Yes. The core and wear layer are waterproof, so standing water on the surface will not swell the plank. Water that gets under the floor through unsealed edges can still trap moisture, so wipe up spills.

Can I install it over tile or concrete?

It floats over most flat, hard, dry subfloors, including tile and cured concrete. The subfloor must be level within about 3/16 in over 10 ft, and you leave an expansion gap at walls.

How much floor does one carton cover?

Each carton holds 18.78 sq ft of 9-1/2-in by 47-3/4-in planks. Add about 10 percent for cuts and waste when you work out how many cartons a room needs.

How does the 22-mil wear layer compare with other vinyl planks?

It is thicker than the 6- to 12-mil layers on most budget vinyl planks and closer to light commercial grades. That means better resistance to scuffs and wear in high-traffic rooms.

Does it need underlayment?

Most click-lock vinyl planks need a thin underlayment or a smooth, flat subfloor. An underlayment also cuts the hollow sound of a floating floor.

Can it go in a bathroom or basement?

Yes. The waterproof construction suits bathrooms, laundry rooms and basements. In a full bath, seal the perimeter and wipe up standing water so it does not seep under the planks.
