Professional hints from the carpenter

for your project with UPB boards made of Resysta - FAQs

 

Due to their natural look and feel and their weather resistance, UPB boards made of Resysta are ideally suited for outdoor areas and especially damp rooms such as indoor pools, spa areas or even wet rooms. In general, there are no limits to the imagination of processing. However, the specific features of the material must be taken into account for planning and implementation.

 

With Resysta UPB boards many shapes can be realized thanks to their thermoplastic properties. They are homogeneous in their structure. Industrial production guarantees consistent quality. There are neither longitudinal nor transverse fibers, which is why constructive support is needed for larger areas.

 

Therefore, UPB boards must be structurally supported (for example, frames or full-surface bonding) to avoid unwanted deformations.

 

Please note:

Do not exceed 15 mm of the fastening point to the edge, as this can lead to deformations in the edge area.

 

Please note:

Do not exceed the maximum fixing distances to avoid unwanted deformation of the boards.

2. Processing Tips

 

2.1. 

Are UPB Boards thermoformable and how?

Yes, allow UPB Boards to warm to 120°C for a short period, allow to deform and to cool down. The heating time depends on the thickness of the plate. For further details please refer to our technical information leaflet.

2.2. 

What has to be considered with thermoforming? 

Thermoforming can cause UPB Boards to shrink. This has to be taken into account when cutting. Only cut to final desired size after deforming.

2.3. 

Which tools can be used? 

All common woodworking tools can be used. 

2.4. 

How can well-shaped edges be produced? 

Sawing has to be done clean and without

hurry. If need be, the edge has to be 

reground only slightly after sawing. 

Glueing is not necessary.

2.5. 

Is screwing of UPB Boards possible? 

Yes, very well indeed. In addition UPB Boards feature very good screw extraction values.

2.6. 

Can UPB Boards be glued?

Yes, UPB Boards made of Resysta can be bonded very well with a variety of adhesives. - For details regarding the type of adhesive and substrates, please refer to the Tech Info leaflet and the instructions of the respective adhesive manufacturer.

2.7. 

Can I divide a 20mm UPB Board to obtain 2 x 10 mm sheets? 

This is generally possible but not recommended as it results in asymmetrical properties and less stability.

2.8. 

What happens when UPB Boards are heated at 120°C for too long?

This could result in thermal damage. Do not heat any longer than necessary for deformation (details are available in our technical information leaflet).

 

3. Recycling Tips

 

3.1. 

Are UPB Boards recyclable?

Yes, very well indeed as the material Resysta is a  thermoplast. UPB Boards made of Resysta have been awarded for their sustainability with the Green Product Award. Resysta has created its own recycling loop. For current take-back locations please refer to www.resysta.de. New products made of Resysta are produced from the returned material.

 

4. Installation Tips

 

4.1. 

 

Which types of fixing works with UPB Boards? 

Best are screws and 

glues.

4.2. 

Which mounting distances have to be observed? 

The mounting distances have to be adjusted depending on the application and thickness of the material. For details please refer to our technical information leaflet.

4.3. 

What happens if the mounting distances are too big? 

Undesired deformations may occur.

4.4. 

Is installation of full board possible? 

Yes, either by means of all-over adhesion or with appropriate constructive support.

4.5. 

Is it possible to install UPB Boards on facades without

rear ventilation?

This needs to be evaluated on an individual basis by an architect/planner (refer to vapour diffusion resistance in the technical information leaflet). Installtion on outside facades without rear ventilation is not recommended.

4.6. 

What has to be considered in the case of glued facades? 

As a general rule, we do not recommend glueing UPB Boards to facades.

4.7. 

Which substructure is recommended? 

Aluminum substructures are particularly recommendable. 

4.8. 

Are sliding points and fixed points necessary with screwing?

Sliding points are not necessary.

 

5. Application Tips 

 

5.1. 

What are particularly recommendable and suitable applications for UPB Boards?

Everywhere, where durability and longevity are particularly important. (e.g. outdoor areas)

5.2. 

Applications NOT recommended / NOT suitable for UPB Boards?

Everywhere, where the board requires constructive and static properties.

5.3. 

Can UPB Boards also be used as table tops? 

Yes, with an appropriate frame construction, UPB Boards are well suited as table tops – due to their wheather resistance, UPB Boards are particularly suited for outdoor use.

5.4. 

Can UPB Boards be used to build furniture, e.g. cupboards, chairs etc?

Yes, depending on the design, constructive reinforcements are necessary.

5.5. 

Can UPB Boards also be used for flooring? 

Yes, if all-over installation and glueing. 

5.6. 

Can UPB Boards be used for constructive works?

Due to the thermoplastic properties, UPB Boards on their own are not suitable for constructional use. With appropriate substructure or frame construction larger surfaces can be engineered.

5.7. 

What has to be taken into account when used as shower screens?

All-over glueing and suitable surface coating has to be chosen.

 

6. Surface Tips

 

6.1. 

Do surfaces have to be treated for protection?

Resysta does not require any protection in terms of wood preservation (against rotting, decomposition, fungal decay etc.). Surface treatment for visual reasons only , e.g. to protect against soiling and staining.

6.2. 

Why are there specific Resysta colors?

Wood varnishes for outdoor use are permeable to water vapour and decompose to avoid peeling (causing high renovation effort and costs). Varnishes for metal and plastics, on the other hand, seal the surface. However, there are no transparent colored metal or plastic varnishes available, so this is why we have delveloped our own varnish that visually enhances the natural wood structure of UPB Boards. For non-weathered areas (indoors) all commercially available water-based lacquers and stains can be used. 

6.3. 

Why are different surface coatings available? 

For UPB Boards made of Resysta surface coating, we provide specially coordinated products according to requirements and application. 

  

  

1. Resysta RBP-Primer, RCL Color Glaze and RCL Clear Lacquer: Transparent stained lacquers for interior and exterior decorative color design, e.g. facade, fence, roof soffits (water-based, quick-drying and easy to process).

  

  

2. Resysta RBP-Primer, FVG Stain und RFS 2-Component Lacquer: Transparent tinted stains are coated with an additional 2-component clear coat for mechanically and chemically highly resistant indoor and outdoor surfaces, e.g. floors and utility furniture. On facades, the surface is graffiti resistant.

  

  

3. Resysta RTO OIL: Naturally transparent colored oils, which can be applied and refreshed quickly and easily, ideal for easily accessible areas such as floors.

6.4. 

Why aqueous paints and no solvent-based surface coatings?

Solvents attack the polymer content in UPB Baords made of Resysta and visually change the surface. For transparent coatings, the change in appearance is visible. Aqueous systems behave neutral towards the Resysta surface and feature very good adhesion.For opaque coating, solvent-based lacquers can be used, as the visual change is covered. 

6.5. 

Is it possible to use commercially available coating systems?

Generally all commercially available systems used for wood, metal or plastics can be employed. For visually good results, we only recommend solvent-free, aqueous lacquers for plastics.

6.6. 

Are Resysta surfaces resistant against graffiti?

Graffiti resistance is achieved by the type of coating. Chemically resistant surfaces can be difficult to dissolve with solvent, therefore grafitti can only be washed off on 2K Resysta RFS lacquer with a solvent (benzine).

6.7. 

How durable are Resysta lacquers (warranty)?

This is dependent on the kind of application, the type of paint and the quantity applied. The thicker the layer, the more time is required to dissolve the coating. This is also weather-dependent (weather side, sand storm and other mechanical influences) The 25 years warranty is valid for paints offered by Resysta to not flake off (large-scale detachment of pieces of paint).

6.8. 

How can lacquer/stain/oil be removed?

Coating of surfaces can only be removed by sanding.

6.9. 

How can damages (scratches) be removed? 

Scratches or mechanical damages can be easily reprocessed with the same products used for wood surfaces (by spot repair or repainting).

6.10. 

Does the rear side also have to be painted?

Due to coating, the surface tension is different. To avoid warping, the rear side should at least be coated with primer. 

6.11. 

Are there any color differences between RCL and FVG colors?

 

FVG stain is a water-thin pigmented stain with low solids content. Therefore the pigmented film thinly covers the uppermost layer of the sanded surface of the UPB Boards. RCL is a high solids content lacquer with scattered pigments. Since the different kinds of paint have different coat thickness in which the pigments are distributed, the effect and thus the color is always slightly different – giving it a natural appearance.

 

6.12. 

How can differences in color occur? 

All surface coatings provided by Resysta are transparent colored. The particular color depends to a great extent on the quantity applied and the preparation of the material to be coated. We therefore recommend to test the color in an invisible area before processing and only use it extensively after checking on the material to be coated.     

 

6.13. 

How can coated Resysta surfaces be cleaned? 

Depending on the type of coating, the surfaces can be cleaned with commercially available household cleaners. For stubborn dirt, we offer a cleaning concentrate - Resysta Surface Cleaner RSC. When using high-pressure cleaners, sufficient distance to the surface must be ensured to avoid harming the coating.

6.14. 

Are Resysta lacquers sprayable? 

Yes, for details please refer to the technical information of the individual lacquer.
