In order to ensure that you will enjoy years of pleasurable use from your floor, please go through this brief checklist prior to laying.
1. Examine, wether between floor and door is enough space (at least 1 cm) so that after the laying of the mats and the laminate the door still can be opened and closed, if necessary shorten the door.
2. Is the space which you are going to be installing the product, suitable (no damp rooms)? Be aware of the type of flooring you are using!
3. The following subfloors are suitable: V100 subfloor planks; old flooring such as PVC (if full-surface adhesive is used); wooden flooring, ceramic tiles, linoleum, cement floors. *The readiness of the subfloor for installation must be ascertained. If a measurement protocol of residual moisture is not performed, the manufacturer will not make good on any claims.
4. The following subfloors are not suitable: Thick carpeting with long fibres is too soft and must be removed prior to installation. Composition flooring contains too much residual moisture.
5. Pretreating the subfloor. Only install Kronotex flooring on subfloors that are absolutely dry, even, solid, stable, and clean. Minor unevenness will be equalised by the underlayment pad. Unevenness of greater than 4 mm should be sanded down to 1 mm or smoothed out with putty. Be sure to sand down any highspots. Lay new planks in such a way that they run perpendicular to the existing ones.
6. Use of underlayments: In order to provide a moisture and vapour barrier when laying the material on a mineral substrate or on a floor with radiant heating, foam underlayment with diffusion-proof PE foil with a minimum diffusion thickness of 0.2 mm must be integrated. Subfloors that lie directly on the subsoil or are subject to fluctuations in temperature require a vapour barrier comprised of a PE foil underlayment with a minimum thickness of 1.2 mm. This applies to such spaces as greenhouses without cellars or that are located over unheated rooms, corridors, ect. Strips should be glued down or installed with at least 20 mm of overlap, and should also be positioned about 5 cm above the base of the wall and subsequently covered with the baseboard.
7. For impact sound and thermal insulation, please use underlayments such as PE foam, felt, or Kronotex Laminate flooring with ”Sound Design” footfall sound reduction. You can also use, for this purpose, Kronotex combination underlayment pads which are comprised of moisture-regulating corrugated cardboard. These pads are laid joint to joint and are glued down with moisture-resistant self-adhesive tape (advantage: the whole job consists of only one step).

8. Allow for expansion joints. Kronotex floorings are a natural product and inasmuch as the base material (wood) has the properties of a natural product, planks expand or contract in all four directions. Consequently, on all surfaces to which flooring is applied, expansion joints of at least 10 mm or 1.5 mm per running metre must be allowed for all vertical surfaces (pipes, conduits, thresholds, columns, room dividers, ect.) Spacers (to be removed after installation is completed) are used to localise these expansion joints.
9. Spaces that measure more than 12 m and/or 8 m in terms, respectively, of plank length or width, require an extra expansion space of a minimum of 10 mm or 1.5 mm per running metre. This applies as well to doorways, openings between rooms and corridor corners. We recommend removing plank tongues in the area around the expansion profile in order to allow for sufficient expansion space. Under no circumstances should the floating system be removed in whole or in part. Mouldings should be attached to the wall only, and not to the flooring.
10. Cover the expansion spaces. After installation, expansion spaces around the perimeter of the floor as well as transitions to other flooring need to be covered with base or shoe mouldings that match or are colour coordinated to blend with your floor. Kronotex has trims colour coordinated to Kronotex floors that can be used to cover wall expansion spaces. To see our complete line accessories, visit your nearest Kronotex dealer.
