Laminate flooring can be an attractive and affordable option for basement flooring. However, basements present some unique challenges when installing laminate floors. Careful planning and preparation are needed to ensure success. Here is what you need to know about using laminate flooring in basements.
Assessing Basement Conditions
The first step is to assess the current state of your basement. Look for any moisture or drainage issues that need to be addressed before installing laminate flooring.
Check for Signs of Moisture
Excess moisture is the enemy of laminate floors. Look for signs of water intrusion like efflorescence, mold, or mildew on the walls and floor. Check for musty odors as well. Use a hygrometer to measure humidity levels, which should be below 50 percent.
Evaluate Drainage
Make sure your basement is properly graded and water flows away from the foundation. Downspouts and gutters should direct water away from the home. Use a dehumidifier and fans to actively circulate air.
Inspect the Subfloor
The subfloor must be flat, clean, and dry. Concrete should be cured for at least 60 days. Level any uneven areas with floor leveling compound. Test concrete slabs for moisture using a calcium chloride test.
Consider a Floating Floor
Floating laminate floors are not adhered to the subfloor, allowing natural expansion and contraction. This is ideal for basements where moisture issues are a concern.
Choosing Appropriate Laminate Flooring
Not all laminate floors are suitable for basements. Choose a product rated for basement use.
Look for Water-Resistant Laminate
Seek out laminate flooring made with water-resistant cores and edges to prevent moisture damage. HDF and fiberboard cores are more water-resistant than traditional laminate.
Choose Thicker Laminates
Opt for 12 – 15 mm thick laminates, which are more durable and less prone to moisture warping than standard 7 – 8 mm floors. Thicker floors feel more substantial underfoot.
Get Floors with Attached Underlayment
Laminate with pre-attached underlayment saves installation time. Foam underlayment provides moisture protection and cushions floors.
Consider Flooring with Antimicrobial Protection
Some laminate flooring contains antimicrobial treatments to resist mold and mildew growth. This added protection is useful in damp basements.
Preparing the Basement for Installation
Taking time to properly prepare is key to laminate flooring success in basements.
Clean and Vacuum the Subfloor
Remove all debris, dust, and dirt. Vacuum the subfloor using a fine filtration bag. Tack or sweep to remove any loose material.
Layout Planks and Calculate Transitions
Dry lay planks across the room to visualize layout. Plan transitions at doorways and between adjoining spaces. Allow 1/4 inch expansion gaps.
Seal Concrete and Finish Imperfections
Use concrete sealers to waterproof porous concrete slabs. Fill any cracks or voids with patching compound. Sand down high spots.
Add Vapor Barrier for Extra Protection
A 6 mil polyethylene vapor barrier provides an added moisture barrier against ground moisture coming through concrete.
Acclimate Flooring 48-72 Hours Before Installation
Allow laminate flooring to adjust to basement temperature and humidity before installing. Following acclimation guidelines prevents buckling.
Installing Laminate Flooring in the Basement
Follow the manufacturer’s installation guidelines closely. Allow the planks to float freely rather than adhering floors to the subfloor.
Start Installation at Exterior Wall
Begin flooring installation along the exterior basement wall. Work from left to right across the floor.
Use Moisture-Resistant Padding
Foam underlayment with a plastic moisture barrier provides a protective cushion between the laminate and subfloor.
Provide Adequate Expansion Gaps
Leave 1/4 inch expansion gaps along all walls and vertical surfaces. Laminate needs room to expand and contract.
Stagger End Joints by 6-8 Inches
Stagger laminate rows so end joints do not align. Offsetting seams adds structural integrity.
Use T-Moldings at Doorways
Install T-moldings between rooms and at doorways to allow separate motion of the flooring in each room.
Caring for Laminate Floors in Basements
Laminate flooring requires some simple maintenance to keep it looking like new.
Sweep and Dry Mop Regularly
Sweep or vacuum to remove surface dirt and grit. Follow up with a microfiber mop slightly dampened with laminate floor cleaner.
Apply Floor Protectors on Furniture Legs
Attach felt pads to chair and table legs to prevent scratching and scuffing of the floor’s protective wear layer.
Control Home Humidity Levels
Use dehumidifiers or humidifiers as needed to keep indoor relative humidity between 35% and 50%. Avoid excessive moisture.
Clean Spills Promptly
Immediately wipe up any water or other liquid spills from laminate flooring to avoid possible damage, swelling, and discoloration over time.
Do Not Wet Mop Laminate Floors
Avoid excessive water when cleaning laminate floors. Too much moisture can seep between planks and cause irreversible damage.
Consider Reapplying Sealers Periodically
Reapplying basement floor sealers every 2-3 years provides added moisture protection for laminate flooring.
Frequently Asked Questions
Can you install laminate flooring directly over concrete?
Yes, laminate flooring can be installed directly over concrete. The concrete must be level, clean, and moisture tested. An underlayment and vapor barrier should be used.
What kind of underlayment is best for laminate basement floors?
Closed-cell foam underlayment with a built-in moisture barrier provides both cushy comfort and protects laminate from subfloor dampness.
Should you use glue when installing laminate floors in a basement?
No, laminate floors are designed to float freely rather than be glued down. Glue can void warranties and prevent the planks from moving naturally.
Can you install laminate flooring over vinyl basement floors?
In most cases, yes. Ensure the vinyl is well-bonded, smooth, and contains no wax. An underlayment helps smooth small imperfections.
Is laminate flooring a good option for finishing a basement?
Yes, laminate can be an attractive, affordable, and easy-to-install basement flooring option. Choose moisture-resistant laminate and take precautions against dampness.
What kind of trim or molding is used between rooms with laminate flooring?
A T-molding is typically used between adjoining rooms or areas where laminate flooring transitions. The T-mold allows floors to float independently.
How long does laminate flooring last in a basement?
Quality laminate can last 15-25 years in a basement when properly installed and cared for. Always follow manufacturer guidelines and warranty details.
Can you install laminate flooring over radiant heat systems?
Yes, but only if the manufacturer specifications state the flooring is rated for use over radiant heating systems. Follow all installation guidelines.
Is laminate flooring a do-it-yourself project for basements?
Laminate flooring is relatively easy for DIY homeowners to install. Just be sure to carefully follow the manufacturer’s installation instructions.
Conclusion
Installing laminate flooring can help transform a dreary basement into a more inviting, livable space. With proper preparation, moisture-resistant materials, and careful installation, laminate can be a durable and attractive basement flooring option. Pay close attention to manufacturer guidelines and warranty limitations. With the right know-how, you can enjoy the looks and longevity of laminate flooring, even in basements prone to dampness. Just take the necessary precautions against moisture and allow the laminate planks to float freely. Soon you’ll be enjoying an eye-catching new floor that makes your basement pop.
