Rappgo's Wide-Plank Flooring is a three-layer flooring with a form-stabilizing core. The visible part of the floor plank shows all the characteristics of a genuine, classic wood-plank floor. The beautiful graining of the heartwood and the knots, embedded for more than a century, now give life to the wood. The construction assures that your floor will be form-stable, without any cracks. We only use the core of the tree. That's how we are able to obtain the best vitality and the rich, beautiful structure out of every plank.

Designed by nature itself, flooring is the canvas, the very backdrop of interior design and therefore, a vital element of the overall impression. Rappgo, with its several different layers of real wood, provides a strong, stable, and timeless floor. A choice you'll never regret.

>Our wood floors are delivered treated with formaldehyde-free, environmentally friendly UV- hardened finish. The pine and spruce boards can also be received lye-treated only or lye-treated and oil finished. All species of wood can be delivered completely presanded unfinished or factory oiled finished.

Type of flooring: 1 strip wideplanks, 3-layer construction, lacquered, oiled, lye-treated or unfinished (sanded) surface

In General:
Keep the floor boards in their packages unopened, in dry storage until installation. They should be stored in the room where they are to be installed for at least 24 hours.

For the comfort and well-being of the people in the building - during and after installation - consideration must be given to maintaining healthy air inside. This is also very important to ensure the quality of your wooden floor. When the room temperature is between 18-22 degrees Celsius (65-70 degrees F) the relative air humindity (RH) should be 40-60 %. This helps to control floor movement like crowning or cupping, cracks in the surface, gaps between the boards and to avoid static shocks. Appropriate measures must be taken to attain these conditions, like using plants in the rooms or humidifiers if the air is too dry, especially during the heating period.

Attention: Claims regarding any visible defective floor beards must be made prior to installation. If you notice any defective boards please sort them out and contact your local dealer.

The Subfloor:
The subfloor must be level, dry, clean and firm.

Our wood floor can be installed on a variety of subfloors including concrete, plywood, particle board, linoleum, wood and ceramic tile. Rappgo floors can be floated, glued down or nailed down. Full-area glueing has to be done by a professional. A floating floor is glued together only in the joints, but is allowed to "float" unattached on top of the subfloor.

On concrete, it is necessary to check the moisture content prior to installation. It must be cured a minimum of 60 days before installation of a wooden floor. The moisture in cement-concrete-subfloor may not exceed 2,5 %, in anhydrite not more than 0,5 %. In general, when installing on below grade concrete or if there may be any moisture in the subfloor use a min. 0,2 mm polyethylene sheeting as insulation against moisture. In rooms with any cellar underneath or in rooms above rooms with higher humidity use even a 2 mm polyethylene sheeting. The sheets must overlap by at least 20-30 cm (12") and be turned up along the walls. For best results seal seams with PVC-tape. When installation is complete cut away excess polyethelene along walls Attention: any kind of sound insulation must be laid always on top of a moisture barrier, never underneath. As sound insulation you can use high density foam, cork or other approved underlayment-material. Do not overlap! When nailing down your floor, 15 lb. floor felt or rosin paper can also be used..

Before Installation:
It is important that you preplan the installation. Measure the width of the room. Normally, it will be necessary to cut the last run of boards lengthwise, but when it becomes less than 2" wide the first run of boards should also be cut. In this case measure so that the first and last runs will be approximately the same width.

Provide expansion gap of about 10 mm (1/4" to 3/8") between the floor and the walls. This is also necessary around pipes, columns etc. During installation use the wedges to maintain proper gap. The distance between the wedges should not be more than approx. 50 cm (20") Up to a maximum width of 8 meter per room you can install the floor without having an additional expansion gap within the room.

Stagger end joints in adjacent runs by at least 50 cm (20 ") !! This is important especially when it comes to narrow rooms.
