General questions about our products
Here you will find all answers to your general questions about our products for floor, wall and ceiling design.
Wood and wood-based materials are so-called hygroscopic materials. This means that they adjust their own moisture content in a permanent process to the ambient humidity. If the ambient conditions in the room, such as temperature and humidity, vary greatly, the floor covering reacts by changing volume and shape – the planks cup or warp. You can easily prevent this by keeping the indoor climate conditions largely constant at 18–22° C and about 60% relative humidity.
If the floor covering bulges in the middle of the room, this can have several reasons. It may be that you have not left a sufficient expansion joint at the walls and that the planks are "pressed" against the wall. Furthermore, the humidity in the room may be too high and the wood of the flooring reacts by increasing in volume. This also applies if the temperature of the underfloor heating is set too high.
If there is a rare case in which you wish to make a complaint about a Parador flooring, please contact our contract partner or your dealer. They will handle the complaint in the interest of both parties.
Yes, this is completely normal for floor coverings, especially for flooring made of wood or wood-based materials. All materials permanently adjust their moisture content to the ambient humidity, which leads to movements and noise in the flooring in case of the usual floating installation.
If it is a floating floor covering such as laminate or engineered wood flooring, you should remove the old floor covering in any case. Coverings that are firmly glued over the entire surface, on the other hand, can remain in place. For hygienic reasons, carpets should always be removed.
We indicate on the leaflet for each floor covering whether it is suitable for use on a hot water underfloor heating system. Electrical temperature control systems for the flooring often work with higher temperatures, which is why we do not recommend the use of our flooring here.
Some of our engineered wood floorings can also be glued over the whole area. The products Trendtime 3, Edition New Classics with tongue-and-groove connection and Open Frameworks with loose and fixed tongue and groove connection are even designed exclusively for whole-area gluing and are not suitable for floating installation. The following applies to the selection of the adhesive:
- only the water and solvent-free, one or two-component (1-C or 2-C) polyurethane adhesives recommended by the adhesive manufacturer for this purpose, or solvent-based adhesives according to DIN 281, are to be used as large area adhesives. The adhesive manufacturer's instructions regarding the amount of adhesive to be applied must be observed, the size of the serrations on the adhesive spatula depends on this.
- Parador recommends the adhesives T54 FC and 151 Objekt made by Sika. These adhesives are suitable for all common types of wood such as beech or oak. If you have specific questions, please contact the adhesive manufacturer and refer to the relevant technical data sheet.
- In principle, the substrate must be dry, level, free from cracks, clean and suitable for gluing and must be below the corresponding moisture values. The pre-treatment/priming depends on the specifications of the adhesive manufacturer.
To ensure that your new floor covering is not damaged by rising damp from the substrate, screeds must not exceed certain moisture values. Decisive for these values are the screed material (cement or anhydrite/calcium sulphate screed) and the question of whether underfloor heating has been installed or not.
- Anhydrite screed
without underfloor heating: max. 0.5 CM %
with underfloor heating: max. 0.3 CM %
- Cement screed
without underfloor heating: max. 2.0 CM %
with underfloor heating: max. 1.8 CM %
The abbreviation CM stands for the commonly used measuring method (Calcium carbide Method), which should only be performed by an experienced professional. A sample is taken from the screed and checked for moisture content. The test material must be taken from the lower third of the screed structure, whereby the thickness of the screed must be measured and documented at each test point. The specifications are only valid for screeds without additives. For screeds with additives, such as
Care and maintenance
Basically our recommendations are the same across all flooring types:
- with felt glides under furniture or soft castors under office chairs you can avoid scratches and impressions on the surface
- regular cleaning should be done dry with a vacuum cleaner or soft broom
- if you wipe the flooring in case of stubborn dirt, wring out the mop so that you only wipe it damply
- under no circumstances should you use scouring agents, floor waxes, hot steam cleaners or polishes for cleaning
