Installation review

We thought we would start this post by reviewing some of the important points in our installation instructions. It is no secret that a perfect floor is only as good its installation. If you follow the Elastilon installation instructions, posted on this website, installing hardwood floors on concrete will be a breeze. Be it glueless bamboo flooring, engineered wood flooring or solid wood flooring, it can be installed with Elastilon. Let’s start with the preparation needed even before you start your floor installation.

Preparation

Please carefully review the instructions for both Elastilon and your flooring material before starting your project. Be sure to inspect all flooring thoroughly before installation to ensure that there are no visible defects. It is the responsibility of the owner / installer to ensure that the material, the environmental and the sub-floor conditions are acceptable before the installation commences. The following instructions comply with the recommendations as outlined in the Installation Guidelines and Methods published by the National Wood Flooring Association (NWFA). Additional application information is available at www.NWFA.org

As wood is a natural product, it is important to recognize that hardwood floors will be affected by the levels of humidity and temperature within a room. The climate conditions in the room need to be maintained prior (at least 14 days), during and after the installation. The installation site must have a consistent room temperature of 60-80F (16-27C) and humidity level between 40-65% maximum (maintaining humidity levels closer to the upper range is recommended). Permanent air conditioning and heating systems need to be operational at all times. Care must be taken with wood stoves and electric heat which tend to create very dry conditions. The use of dehumidifier or humidifier depending on the situation may be necessary to maintain desired results. For complete details on how to deal with wood floors and the environment, please refer to the NWFA publications (No. A100 – Water and Wood / No. C200 -Problems, Causes and Cures).

Job site preparation is necessary for a proper installation. Be sure to follow the minimum job site recommendations listed in Section 1, Chapter 1 of the NWFA Installation Guidelines and Methods.

    Please type your comments here.Is it necessary to remove black mastic before installing elastilon over concrete?

      Hi Pat
      We do not recommend Elastilon to put flooring boards onto stairs. An Elastilon floor is a floating floor, and it is the weight of the flooring that holds the floor in place. Flooring boards used as stair treads must be nailed or glued in place.

        Quite simply yes! There relaly is not a simplier way of installing a hardwood floor on concrete and that includes such exotics as bamboo flooring. Be sure to watch our installation video and read though our detailed installation instructions. Both can be found on this website. If you have specific questions, please give us a call on our toll free information line. One our technicians will be happy to help you through the process.

      Hi Pat,
      Elastilon can be used to install a floor over any surface that is flat and sound. If the surface is smooth enough so that the Elastilon will not be caught or tangled in the mastic, and it is flat, within 1/8 inch over 6 feet and within 3/32 inch over a 10 foot radius, then you will not have to remove the mastic. If it is not, then you will have to sand or grind the mastic flat and smooth. In any case you should put down a 6 mil or heavier plastic vapour barrier first because this is on concrete. The Elastilon will then slide easily on the plastic, and the smooth mastic will not grab the Elastilon through the plastic

      I am installing 3/4 in solid hawoddors in my walk out basement over elastilon, which is laid over 6 mil poly. unfortunately I do not have a long wall to start against so we picked the main focal point which is the exterior french doors for the location to start. I want to confirm, before I get started, that I can leave an expansion gap of only 1/4 inch. The hardwood flooring instructions recommend 3/4 inch but there will only be quarter round moulding to cover the gap in front of the door so 3/4 of inch is too large.

        Let me begin by offering some important points when installing a floor with Elastilon in a basement with a walk out entrance. Be sure that there is a 6 mil poly on the concrete, over lapped by 8in and sealed with water resistant tape on the joints. The poly should completely seal that floor which means it should run up the walls and then be fastened behind the baseboards when they are reinstalled. At the door, the poly needs to be sealed to the floor with a bead of construction adhesive near the end of the door sill. It is also important to control the environment where ever you install solid hardwood flooring. The use of a dehumidifier or humidifier may be necessary depending on the room conditions. Be sure to follow the manufacturers recommendations in terms of the recommended humdity levels in the room. Lastly, be sure to place a floor protector (mat) at the entrance of the door to help minimize the dirt and moisture on the wood flooring below.

        Now for the expansion, it is important to allow for the expanion of the floor especially in areas where there can be constant changes in the environment. Opening and closing an exterior door can change the conditions in a room and because of this the expansion gap is important. If you decide to leave only 1/4″ for expansion then the additional expansion has to be added to the opposite side of the room. That means you will need to add 3/8″ to the opposite wall in the room. It might mean you will need to undercut the drywall on that side of the room to allow for the extra movement.

        Another option is to place a flat molding against the outside door. You could use a door stop molding with the flat edge against the door sill and the rounded edge toward the room. Most door stops are at least 1″ wide which will cover the 3/4″ required. They are usually only about 1/4″ to 3/8″ thick so it will not be obtrusive. Just be sure to glue the molding to the sill and not to the floor itself. The floor needs to be completely free floating.

    Dear Betsy,Elastilon is a free floating inlialsatton membrane that requires an expansion gap around all walls and any solid obstacles. In a basement environment it is especially important to allow the floor to expand with the increased potential for changes in moisture levels. The recommended expansion gap is 5/8” but if this is not possible then additional expansion must be added to the opposite wall. Therefore if only bc” is left on the one wall, the expansion gap on the opposite wall must be 3/8” plus the original 5/8” for a total of 1”. To help accommodate the 1”, the drywall along this wall can be undercut to allow the flooring extra expansion space. This can add up to bd” additional expansion space.Depending on the environment, it might be necessary to use a humidifier or dehumidifier to control the moisture. It is also important to use a moisture barrier under the Elastilon in any below grade application.

      Fred, you should dnteeifily consider installing Elastilon in your basement. It is the only way to install solid hardwoods in basements. I read the comment from Ms Smith about the Lowes store. I have experienced this narrow minded attitude by others who simply cannot accept a new concept..If you buy it at Lumber Liquidators, they will offer you installation as well (I am an installer and the company I work for does work for them:)
