|MDF boards or chipboards coated with paper impregnated with a special MF resin that offers the ideal base for the subsequent application of lacquer or paint. The special structure of the varnishable surface provides good primer, lacquer or paint adherence. It reduces the need of pretreatment depending on the quality of the paint used. Other advantages of the VARNISHABLE surface are the following:|
It makes the application of a uniform layer of coating easier. It also helps in the uniform absorption of the coating.
It reduces the swelling of the wood particles of the surface.
It reduces possible drying flaws.
It is compatible with the use of paintbrushes, paint rollers or paint guns. The elementary rules for this type of applications must be respected, so as to prevent the formation of drops, strips due to the superimposition of layers, drying pores, etc.
FIMAPAN VARNISHABLE/FIBRAPLAS VARNISHABLE meet Class E1 requirements (low formaldehyde content) as defined in UNE-EN 14322 Standard.
The physical-mechanical properties of these products will be those of the baseboard used.
Pretreatment: fine grain sanding (180-240) and subsequent cleaning of the surface. With some types of lacquers/paints, it is possible to do without the previous sanding, provided that their anchorage is confirmed.
In order to prevent the surface from getting dirty, it is important to handle it carefully.
The application of paint must be done at room temperature, between 12 and 20ēC, and a relative humidity inferior to 85%. Any changes in these conditions will influence the drying times, the flow of paint...
The drying times specified by the paint manufacturer must be respected. It is important to notice that the reactions between paint drying and curing times may take several days.
In the case of lacquered finishes, a good result may be obtained only with one layer, though for dark colours or special finishes it may be necessary to apply a second layer.
In those cases where the application of a lacquer includes the edge of an MDF board, this must be accordingly sanded and sealed with an suitable primer. It may be necessary to apply several layers; in that case, a fine grain sanding is recommended after each application.
It must always be stored under cover and on a flat surface.
65% of humidity is the ideal condition for its storage, dryer or more moist environments should be avoided.
It must never be in direct contact with water.
Blocks must always be lined up with the vertical.
Never pile up more than 4 heights.
If the packaging is damaged during its handling, it must be packed again so the product is correctly preserved.
If the piling-up conditions or the changes in moisture or temperature above mentioned are not respected in the warehouses or the processing areas, they may cause irreversible deformations and warpings.
