Description

Description

MoistureBlock is a 6 mil polyethylene vapor barrier underlayment designed to protect laminate, wood, and vinyl flooring from damaging subsurface moisture. Sized for convenience, this 2.5 ft. x 40 ft. roll covers 100 sq. ft. and lies flat for quick and simple installation. It’s ideal for small to mid-sized jobs and works effectively over most subfloor types. The self-sealing seams make it easy to create a continuous moisture-resistant layer that extends the life of your floors.

FAQS

What is the difference between hardwood and engineered wood flooring?

Hardwood is made from solid wood planks, while engineered wood has a real wood surface over layered plywood, making it more stable and moisture-resistant.

Is porcelain or ceramic tile better for my home?

Both are durable, but porcelain is denser, more water-resistant, and ideal for high-moisture areas, while ceramic offers a wide range of designs at a lower cost.

Can laminate or LVT be installed over existing floors?

Yes, both can often be installed over most existing floors, provided the surface is clean, dry, and level.

Which flooring options are waterproof?

Porcelain tile, ceramic tile, and most LVT products are waterproof, making them perfect for kitchens, bathrooms, and basements.

How do I maintain my flooring for long-lasting beauty?

Sweep or vacuum regularly, clean spills promptly, and use manufacturer-recommended cleaners to avoid damage.

Which flooring option is best for high-traffic areas?

For spaces like hallways, kitchens, and commercial areas, durable choices include porcelain tile, LVT, and high-AC-rated laminate.
