For standard wood-to-wood installations, you generally do not need to put anything between the subfloor and the wood underlayment. Fastening the layers securely together is what prevents squeaks. However, depending on your flooring type, specific materials are sometimes used to address moisture, sound, or friction.
Underlayment is a thin layer placed between the subfloor and the flooring material. When installing new flooring, the underlayment is often overlooked.
The "Rule of 3" in flooring is a design principle that recommends limiting your home to a maximum of three different flooring types, tones, or textures. This restraint prevents spaces from looking busy or disjointed, allowing for a cohesive, visually appealing flow from room to room.
A decoupling or slip sheet can be roofing felt (also called tar paper) or red rosin paper. You put it between a wood finished floor and the underlayment. You do not have to put it between the subfloor (structural wood screwed into joists) and underlayment (wood sheet on top of subfloor to prep for finish floor).
Yes, you can put Kilz on a plywood subfloor. It is highly recommended for sealing in stubborn odors (like pet urine or smoke) and blocking water stains before installing new carpet, laminate, or hardwood.
I'm sure the label means that it isn't suitable as a primer for floor paint. Oil base Kilz will probably seal the odors OK although a pigmented shellac like Zinnser's BIN would definitely seal them. You're fine - it's just not going to hold up if you walk directly on it.
It offers excellent adhesion to both interior and exterior surfaces and provides a sound anchor for paints. The EPA registered active ingredient creates a mold and mildew-resistant film that protects the primer film from mold and mildew growth.
If you're gluing the new flooring to the subfloor, use a sander to remove paint, oil, wax, adhesives, sealers or other material and then thoroughly vacuum off dust and debris. Nail-down or floating floors may be installed over existing vinyl as long as it's no more than two layers thick.
In 2026, flooring trends are moving decisively away from cool grays toward warm, natural tones. The most popular colors are light natural oaks, creamy beiges, honey, and rich browns like caramel and walnut. Across materials, extremely glossy looks are out, with matte and satin finishes leading the way.
black felt paper is rolled out over the wood subfloor prior to installing the new floor. This hardwood felt paper is necessary to greatly reduce the chance of any moisture coming up through the subfloor and will help protect the new hardwood flooring.
The Top 10 Flooring Mistakes to Avoid
The 3-5-7 rule is an interior design principle stating that grouping decor in odd numbers (3, 5, or 7) creates more visually balanced, dynamic, and natural-looking arrangements than even numbers, which can feel too stiff or symmetrical.
True 100% waterproof flooring prevents water from penetrating the core of the material, making it ideal for bathrooms, kitchens, and basements. The most popular options are Rigid Core Vinyl (such as SPC) and Porcelain/Ceramic Tile.
For plywood subfloors, screws are heavily recommended over traditional nails. While framing nails rely on friction and can work loose over time (causing the floor to creak and squeak), subfloor screws have spiral threads that provide permanent grip and tightly pull the plywood down to the joists.
Generally, no. For most modern framing with joists spaced 161616 inches apart, 1/2-inch plywood is considered too thin and will flex or sag, leading to squeaky floors. The minimum recommended thickness for a structural subfloor is 5/8-inch, with 3/4-inch being the standard for long-term durability.
One of the biggest challenges with subfloors is moisture. Plywood that isn't properly treated or dried can absorb moisture from the environment, leading to swelling, warping and even mold growth. This can cause flooring materials to lift, separate or degrade over time.
Gray-toned hardwood and laminate. Wide plank farmhouse-style wood. Painted floorboards. Artificial or fake-looking wood.
Dark Flooring
Dark-stained floors create a dramatic backdrop that allows furniture to stand out against the rich, velvety darkness. Additionally, the dark color absorbs and reflects light, adding depth and visual interest to the space throughout the home.
There is no single right answer, as both create different vibes. A general design rule is that floors should be slightly darker than the walls to ground the space and provide a solid visual foundation. However, your choice depends on the atmosphere and proportions you want to achieve.
Between the subfloor and your final flooring sits the underlayment. This crucial middle layer smooths out minor imperfections, deadens sound, and provides moisture or thermal protection. The exact material you use depends on the type of finished flooring you are installing.
The wood colors that never go out of style are natural, medium-brown, and classic dark tones. These neutral, warm tones showcase authentic wood grain without relying on trendy, exaggerated stains (such as overly bright golds, cool grays, or stark blacks), allowing them to blend seamlessly with changing decor over time.
No. Modern laminate flooring is designed as a "floating floor," meaning it clicks together and rests on an underlayment without any glue or nails.
Mold is typically worst from late spring through early fall. Because mold thrives on warmth, moisture, and oxygen, the combination of high humidity and rising temperatures creates the perfect breeding ground for spores to multiply rapidly both indoors and outdoors.
The Japanese practice of hanging futons and pillows outside to “air out” isn't just traditional — it kills mold and mites that love humid bedding. Wipe down bathrooms after every use. Exhaust fans during showers, wipe tiles and mirrors, keep surfaces dry. Bathrooms are ground zero for household mold.
To kill mold permanently, you must combine chemical treatment with moisture control. Mold will always return if its food and water sources remain.
