Can you put hardwood on concrete? Here's the truth

In the event that you're staring with a cold, grey slab and thinking can you put hardwood on concrete , the short solution is an unquestionable yes, but there are a few big "ifs" included. It's one of those projects that looks straightforward on paper but can turn into a literal warped clutter if you skip the prep function. Many people assume hardwood needs a wooden subfloor to thrive, although with the best materials and a little bit of persistence, you can absolutely get that high-end look on the concrete base.

The real problem isn't the wood itself; it's what's happening inside the particular concrete. Concrete is usually essentially a huge cloth or sponge. Even if it looks bone-dry to the naked eye, it's constantly pulling dampness from the surface and releasing this to the air. If you trap that moisture under the layer of wood, the wood will be going to earn the fight—and simply by "win, " I mean it'll outstanding, buckle, and ruin your weekend.

The Battle Between Wood and Dampness

Before you even choose your own favorite oak or even maple finish, you have to take that moisture is usually your number one foe. Concrete is porous. If your home is built on a slab or you're finishing a basement, that concrete is sitting directly against the earth. Terrain moisture migrates way up with the slab within a process known as vapor emission.

When you ask yourself can you put hardwood on concrete , you also have in order to ask in case your piece is dry plenty of. If you lay down solid boards and the concrete "sweats, " that wood is going to soak up. This leads in order to cupping—where the edges of the planks sit higher than the center—or crowning, where the middle bulges up. Neither is definitely a look you want.

That's why a humidity barrier is non-negotiable. Whether it's the heavy-duty plastic movie or a specialized liquid sealant, you need something to break the connection among the slab plus the wood.

Solid vs. Built Hardwood

This is how things get interesting. Most flooring pros will tell you that while you can put solid hardwood on concrete, it's generally not the wisest move, particularly if you're below ground level.

Strong hardwood is a single piece of wooden throughout. It's gorgeous, but it's extremely reactive to moisture. It expands plus contracts like it's breathing. On concrete, especially in basements, solid wood is prone to failing since it has nowhere to go when it will get damp.

Engineered hardwood , on the some other hand, was virtually made for concrete. It has the real wood veneer on top, but the core is constructed of cross-layered plywood or high-density fiberboard. This "sandwich" construction can make it way more steady. It doesn't reduce or swell nearly just as much as solid wood, which is exactly why it's the precious metal standard for concrete installations. If you're dead set on wood, you'll likely have to build the subfloor on top of the concrete first, which provides height and price.

Testing Your Concrete Slab

You can't just wing it plus expect the best. You have to know exactly how much dampness is coming out there of that ground. There are the few ways to do that, ranging through the "DIY quick check" to the professional "scientific approach. "

A classic DIY trick is the plastic page test . Strapping a 2-foot simply by 2-foot square associated with heavy plastic to the floor, sealing all the sides with duct tape. Leave it for 48 hours. When you peel this up, if the concrete is dark or there's condensation on the plastic, you have a dampness problem that needs addressing before any wood touches the floor.

For the more accurate reading through, you can get a calcium chloride test kit. This particular measures the moisture vapor emission price. If the figures are too high, you'll need in order to apply a professional-grade moisture vapor retarder. It might think that an annoying additional step, but it's a lot cheaper than replacing a $5, 000 flooring in two years.

Getting the Surface Flat

Concrete is rarely as flat since it looks. Most slabs possess humps, dips, and "waves" that you might not discover until you try to lay a very long, straight board over them. If you ignore these, your floor will experience "bouncy" or create annoying clicking seems when you walk on it.

Grab a long straightedge—a 6-foot or 8-foot level works great—and slide it across the floor. You're looking for any gaps larger than 1/8 of an inch. If you discover a dip, you'll need to fill up it with the self-leveling underlayment . When you find a hump, you might actually have got to grind it down, which will be a dusty, untidy job, but completely necessary.

3 Ways to Set up

Once the particular slab is dried out and flat, you've got three major ways to get the work done. Each has its own advantages and disadvantages depending on your skill level and budget.

one. The Glue-Down Method

This is definitely the most typical way to put engineered hardwood on concrete. You use the high-quality flooring adhesive to bond the particular wood directly to the slab. * The Pro: The particular floor feels incredibly solid underfoot. Simply no "hollow" sounds. * The Con: It's messy. Like, really sloppy. Also, once that will wood is lower, it's down permanently. Taking it up later is the nightmare.

two. The Floating Technique

This is a preferred for DIYers. You lay down the padded underlayment (which often acts since a moisture buffer, too), as well as the boards click together without being attached in order to the ground at all. * The Pro: It's quick and easy on the knees. Plus, the underlayment offers a bit of "give" plus thermal insulation. * The particular Con: It can appear a bit "clicky" or hollow when you walk on this in heels or once the dog runs across it.

3. The Plywood Subfloor Method

This is how you get strong hardwood onto concrete safely. You lay down a steam barrier, then screw a layer of 3/4-inch plywood in to the concrete making use of masonry anchors. Right now you have a wooden surface to nail your hardwood into. * The Pro: You get to use traditional solid hardwood. * The Con: It raises the particular floor height significantly. You'll likely have got to trim the bottoms of your own doors and offer with weird transitions to other rooms.

Don't Miss to Acclimate

One of the biggest mistakes people create when they find out can you put hardwood on concrete is definitely rushing the particular set up. You can't bring the wood house from the factory and begin hammering this down an hour later.

Wood must "get used to" the environment of your home. Open the particular boxes and let the wooden sit within the space where it's heading to be installed for at minimum 3 to seven days. This allows the moisture content of the wood to balance out with the humidity within your house. When you skip this particular, the wood might shrink or broaden after it's installed, leaving you with ugly gaps.

Is It Worth It?

At the finish of the day time, putting hardwood more than concrete is a fantastic method to upgrade a space. It's warmer compared to tile, more durable than carpet, plus adds a lot of value to your home. Just remember that will concrete is really a living, breathing thing. Respect the moisture, select the right kind of wood (seriously, look at designed options), and don't skimp on the particular leveling.

In the event that you take the particular time to preparation the slab properly, you'll end upward with the floor that looks like several bucks and stays that way intended for decades. It's almost all about the foundation. When the concrete is definitely ready, the wooden will follow suit. Simply take some time, perform your tests, plus enjoy the procedure of transforming that cold slab straight into something beautiful.
