Can I install reclaimed pine flooring over a floating subfloor?


We’re listing alphabetically all of the flooring types available so that you can easily determinewhether you can install laminate over that specific flooring type. Remember that laminate flooring, like Swiss Krono USA’s Laminate Wood Flooring, is a floating floor — it will expand and contract as temperature and other conditions change. This means that the choice of subfloor (i.e., what you install laminate over) needs to provide the right support.

Brick: No. Even with a brick floor in excellent condition, there is the potential for too much surface deviance that could stress the laminate-flooring locking system. And if the floor is below grade, moisture migration will be too difficult to control. Carpeting, tufted: No. Carpet, its padding, and all its staples must be completely removed — down to the subfloor — before you install laminate flooring. Carpeting, commercial or needle-bond: No. Some types and styles of commercial or “indoor/outdoor” carpeting may look harmless,...

Make sure your subfloor will support your new flooring.

What goes underneath your floors is as important as the finish material. Not all types of joists and subfloors are appropriate for all types of flooring.

A ceramic-tile floor needs a solid substructure because subfloors in a new home are vulnerable to settling that can damage tile. Confirm that your tile contractor will follow the recommendations of the American National Standards Institute (ANSI) or those in the Handbook for Ceramic Tile Installation published by the Tile Council of America.

Materials such as vinyl and carpeting are flexible enough to tolerate engineered floor truss systems with larger joist spacings, such as 24 inches on center. For ceramic tile, the Tile Council recommends using joists that are 16 inches on center, a 3/4-inch-thick plywood subfloor, and a 1/2-inch-thick cement backer board or concrete slab. Oriented strand board (OSB) and other...

There are a couple misconceptions in your question.

what if my CGFloat is 2.0f but internally it is represented as 1.999999999999f

can't happen; 2.0, like all reasonably small integers, has an exact representation in floating-point. If your CGFloat is 2.0f, then it really is 2.0.

something like 2.0 would never accidentally get ceiled to 2

The ceiling of 2.0 is 2; what else would it possibly be?

I think the question that you're really asking is "suppose I do a calculation that produces an inexact result, which mathematically should be exactly 2.0, but is actually slightly less; when I apply floor to that value, I get 1.0 instead of 2.0--how do I prevent this?"

That's actually a fairly subtle question that doesn't have a single "right" answer. How have you computed the input value? What are you going to do with the...

Is your basement nothing more than an unfinished storage area? That’s the case with many homeowners who consider their basement to lack the warmth and coziness to make it a comfortable living space. When it comes to cold basements, you can blame the floor. The porosity of a concrete floor can make it cold and damp—unwanted characteristics that can be felt through tile, carpet and hardwoods. Simply put, cold basements—even if they’ve been finished—often don’t get as much use as the other more comfortable areas of the house. That’s a lot of space going to waste. Today, floating subfloor systems offer homeowners a way to stifle the cold and construct a warm, pleasant place for a game room, office area or home theatre. These systems offer a two-pronged approach to keeping concrete floors dry and warm.

First, the plywood or oriented strand board (OSB) subfloor floats on a corrugated or “cleated” waterproof underlayment, so the wood never actually touches the floor. The...

For years the only solution to installing hardwood floors over tile was rip it out and install the wood floor.

What Types Of Installations Over Tile? Floating Floors

The simplest in terms of getting the job done without messy demo work would be a floating engineered floor. Floating floors were designed for these types of applications. Styles, colors, and appearances are numerous today specifically with the leader in floating floor technology; Kahrs.

Engineered Glue Down Floor

Only in recent years have some hardwood adhesive manufacturers given the green light to gluing over ceramic, but there are some important considerations before starting the job. For a successful glue down application over older tile the single largest issue associated with failures are older loosened tiled floors. Floors cannot be glued in this condition.

Preparation before installing any glue down floor will require some additional floor work in the form of...

Pine is not only an attractive and inexpensive flooring choice. It’s also easier to install than hardwoods, and wears well over the years. Prices for pine vary according to the wood’s grade and the width of the planks, with antique pine being the priciest. Staining pine isn’t usually necessary. Once treated with oil, a pine floor can achieve its own rich, warm color over time. For ease of installation, choose a material that requires little sanding or none at all.


Choose the grade of pine you will be using. Pine wood is classed in a range from no knots to large knots. Many craftspeople recommend the standard 8-foot-long pine plank, measuring 1 inch by 6 inches in "No. 1" or "No. 2" grade. Choose tongue-and-groove edges as these are easy to put down and the nails won’t show.

Stack your wood in the room where the new floor is planned, so the wood can acclimate to the moisture in the air in that room. Wood flooring acclimates best when indoor...
