Living in West Texas means dealing with unique environmental conditions. From the dusty winds sweeping across Andrews and Big Springs to the intense heat in Fort Stockton, our homes take a beating. West Texas concrete slabs are continuously exposed to temperature shifts and moisture movement from deep beneath the soil. When upgrading your home's interior, installing durable laminate flooring is an excellent way to elevate style while standing up to high foot traffic. However, your new floor is only as stable as what lies beneath it.
Why subfloor preparation matters in West Texas
Skipping proper subfloor prep leads to hollow sounds, buckling, separated planks, and moisture damage down the road. As the premier flooring company in West Texas since 1988, The Design Gallery by Paul Evans maintains the largest in-stock inventory of carpet and hard surface options in the region. Because we purchase materials by the truckload, we pass substantial savings directly to you. To help you get your project done right without delay, our team has compiled this essential subfloor preparation checklist before laying down new planks.
Step 1: Inspect and clean the concrete surface
Before any installation begins, your concrete slab must be completely free of debris, old adhesives, and dust. Any leftover particles create uneven spots that ruin the locking mechanism of floating planks.
Clean up all dirt, paint overspray, and drywall compound using a heavy-duty shop vacuum.
Scrape away old tile mortar, carpet glue, or wax build-up until the raw concrete is smooth.
Check for oil or chemical spills and treat them with appropriate degreasers so moisture barriers adhere correctly.
Step 2: Perform critical moisture testing
Concrete is naturally porous, drawing up moisture from the ground below. High moisture levels break down laminate cores, causing swelling and mold growth.
Conducting moisture tests
Use a relative humidity (RH) sensor test or a calcium chloride test kit across multiple spots on your slab. If your concrete registers high moisture levels, address the underlying moisture source or apply a specialized moisture barrier system prior to laying down your planks.
Step 3: Check for flatness and leveling
Subfloor unevenness is the main cause of plank separation and annoying squeaks. A flat subfloor is essential for a long-lasting installation.
Use a 6-foot or 10-foot straightedge level across the entire room.
Ensure the floor variation does not exceed 3/16 inch over a 10-foot radius.
Grind down high spots on high concrete ridges using a hand grinder equipped with a masonry wheel.
Fill low spots, dips, and cracks using a high-grade self-leveling compound or patch material.
If your concrete foundation requires structural attention before laying new flooring, explore our professional subfloor repair services to make sure your base foundation is solid.
Step 4: Install moisture barrier and underlayment
Installing laminate directly over raw concrete without proper layering will compromise your floor. Protecting your investment requires high-performance damp-proofing.
Roll out a 6-mil polyethylene vapor barrier across the concrete floor, overlapping seams by 6 to 8 inches, and seal them with vapor-tape.
Select the right quality padding by pairing your barrier with premium underlayment to absorb sound, dampen footsteps, and add extra thermal insulation.
Ensure underlayment edges sit tight against one another without overlapping to keep the surface flat.
