Hardwood Flooring Installation Tips

Are you installing hardwood flooring with a radiant heating system?  Here is the advice of Doug Mossbrook, President/CEO of Eagle Mountain:

I recommend using a glue down. I would use an unfinished quarter sawn oak, and I would glue it down using Bostik glue and sand and finish it in place. Either Bostik’s Best or TKO if you want no VOC’s.

It’s what I used in my house and I was gluing Brazilian cherry which moves more than oak. You lay glue in the area that you can cover in about an hour. Tack the first boards in the 6″ space along the wall with nails but leave them exposed to pull out later.Use 1/2″ blocks along the wall to leave an expansion space that will be covered by your 3/4″ shoe molding, and to give you something to push against.

There isn’t any tubing in the 6″ space along the wall of a room so you don’t need to worry about hitting a nail. Then lay your boards and as you slide the T+G together, some of the glue gets in the joint and will bond the wood together. Use a scrap piece as a block and use a hammer to drive the warped ones tight.

Once you have laid the section, use blocking and shims against the opposite walls or flooring strap clamps that you can use to clamp the floor section together while it dries. Once the glue sets you can do the next section. The Bostik glue is elastomeric which makes it very flexible.

The floor can expand and contract as it needs to. You should let the wood acclimatize in the house for a couple weeks before you do the project. This lets the wood equalize it’s moisture content to the surrounding materials. That way it can expand at the same rate when the humidity and temperature changes.

As far as the finish – use only Street Shoe by Basic Coatings. You have to use a certified finisher. He comes and sands and finishes the floor and can fix your other floors at the same time.

Radiant Heating and Hardwood Floors

There is a lot of controversy on the Internet regarding radiant heating systems and hardwood floors.  Our most popular package is the overfloor radiant system, where the radiant tubing comes in direct contact with the hardwood flooring.

The radiant tubing can be in contact with the hardwood flooring as long as the temperature stays within the recommended parameters. Always make sure to use a good quality aluminum heat transfer plate to spread the heat across the floor more evenly. The water temperature should not exceed 140 degrees and the surface temp of the floor should not exceed 85 degrees.

If the wood is a very thin type material, you may want to put Luaun down before the hardwood. This will help reduce the “striping” effect by reducing the temperature at the point of contact. Thicker materials will have the effect of spreading out the heat naturally.

Maple, for example, is one of the most “active” hardwoods in terms of expansion and contraction. Expect there to be gaps during the winter and swelling in the summer. It’s the nature of the wood. We recommend that you acclimatize the wood for several weeks in the space where you are installing the hardwood flooring. This will allow the wood to adjust to the same temp and moisture level as all of the surrounding materials. This is a step that is missed in most installations.

Also, installing the floor during the shoulder seasons is good if possible since the humidity and temperature are in the middle of their range. Expansion and contraction will be 50% in each direction. If you install the floor in the winter, and make it tight, the floor will swell heavily when the humidity rises in the summer.

The same thing for installing it in the summer. If you make it tight then, by winter there will be gaps in the floor.
