Adhesive bonding of wall cladding panels

Adhesive bonding is a reliable and invisible (blind) fastening method that ensures a favourable stress distribution, allows thinner panels to be used and results in a construction with favourable properties in terms of constructional physics.

Adhesive bonding requires a certain amount of expertise and cannot be carried out under all weather conditions. Follow the instructions provided and consult Bostik BV if you have any doubts.

Yes, that has now been proven extensively, both in the field and through independant testing. Simson has 20 years of experience in wall cladding panel adhesives.The adhesive systems are KOMO certified and therefore meets the requirements of the National Building Decree.

The various panel types and adhesive systems are listed in the adhesives guide for wall cladding panels on this website. Consult Bostik if your panel type is not included in the adhesives guide.

Simson PanelTack adhesive systems can be used to bond various panel types: HPL (high-pressure laminate), coir cement, compressed rockwool and wood laminate. Bostik BV has compiled an overview of the panel types and brands that can be used, with specific instructions for each brand.

Yes, you can. However, the use of PanelTack on aluminium panels depends on several factors (panel dimensions, weight, usage conditions, etc.). Always consult a specialist from Bostik before using PanelTack on aluminium panels.

Yes, you can use PanelTack HM to bond stone panels. However, the use of PanelTack on stone panels depends on several factors. Always consult a specialist from Bostik before using PanelTack on stone panels.

The thermal and hygric properties of the panels should be taken into account, particularly in the case of HPL panels. That is why Simson offers PanelTack, a specialised, highly elastic adhesive for wall cladding panels. PanelTack can be used to bond panels with a diameter of up to 3.44 metres without any problems.

Always install the support structure in accordance with the instructions provided by the wall cladding panel manufacturer! These instructions will clearly indicate such information as the centre-to-centre distances of the framework. You can also find this information in the application instructions provided by Simson, which have been geared to the instructions of the wall cladding panel supplier.

Untreated pinewood, meranti or possibly specially preserved wood. The wood type used must be sufficiently durable for building structures in accordance with NEN 6760. Never use oily wood types (pitch pine, Oregon pine, etc.), plywood, MDF or OSB for support structures. Consult Bostik if you have any questions.

The instructions for bonding applications of this kind differ on a number of points from regular applications, for instance the support structure has smaller centre-to-centre distances. Consult the relevant application instructions.

In this type of application it is of great importance to assess first if the adhesive adheres well to the paint, and, possibly even more imortant, if the adhesion of the paint to the substrate is good. Consult Bostik for more information about the use of paint as an adhesive surface. Never apply black wood primer to painted or varnished wood!

Yes, this is possible. We recommend using Primer PanelTack as a pre-treatment.

Yes, you should use wood that has been planed on four sides.

Yes, these should be of aluminium or bright steel. Closely follow the pre-treatment instructions. Support structures of enamelled metal are also possible, but these may require different pre-treatment. Consult Bostik about these matters.

Yes, but the film must be moisture-permeable to prevent wood rot or damage to the wooden support structure, especially if insulation material is used in addition to the film (insulation material retains moisture, causing a significant loss in functionality).

Black wood primer produces a distinct colour difference compared to other (clear) primers. The primer also fulfils an aesthetic function.

Black wood primer (SX Black) is applied in a continuous, closed layer. Use the special application set; do not apply the primer directly from the can. Carefully read the instructions on application and drying times.

The moisture content of the wood may not exceed 18%. This can be measured using a wood hygrometer.

No, this is generally not necessary.

You may also use Easy Clean Wipes to prime (and simultaneously clean) HPL wall cladding panels and aluminium support structures. Consult Bostik for more information.

No. You should only apply primer (while observing the correct drying times) to panels that can be bonded on the same working day. Otherwise the support structure will become dirty again.

Yes, you can use a joint profile. However, such a profile only has an aesthetic function. Joint profiles (aluminium) must not affect the operation of the panel or the ventilation.

Observe the application temperature stated in the technical information. It is advisable to perform a dew point measurement.

Adhesive bonding work should not be carried out on rainy days, on days with a chance of rain, in the event of storm (force 7 or more) and if the temperature falls below 5°C.

Yes, adhesive should only be applied in vertical rills. Adhesives should never be applied to horizontal framework elements (intended for the placement of insulation material). Ventilation must remain possible. In addition, water could collect on horizontal rills, which could damage the entire construction.

If the adhesive is applied in triangular rills, the panel can be positioned without immediately being fixed to the foam tape. Once the panel is in the correct position, press it firmly onto the foam tape and rub or press the panel until it is tightly attached. Applying the adhesive in triangular rills also prevents the entrapment of air in the adhesive.

The protective film was not removed from the panel (or not removed in time), or the panels were stored under wet conditions, producing internal stress. This can be prevented by storing the panels in accordance with the manufacturer's instructions.

Has the protective film been removed from the foam tape? If the triangular rill has been applied too close to the foam tape, the adhesive is pressed over the tape and the foam tape will have no adhesive strength.

Black primer is not suitable for HPL panels and metal. Use Primer PanelTack for these substrates.

Use of Primer PanelTack (wash primer) is usually sufficient, but you may also need to use a cleaner (Cleaner 14) beforehand. Make sure that the cleaner does not damage the panel and that the cleaned surfaces are dry before the panel primer is applied.

Never use Primer PanelTack as a cleaning agent. Use Simson Liquid 1 or SMP Remover instead. Test for damage before use.

We provide high-quality guarantees. After all, this is a reliable system from one of the world's largest adhesive manufacturers. A durable adhesive bond is guaranteed, provided that the product is applied in accordance with the instructions. A special project guarantee is available for larger projects, subject to specific terms and conditions. Consult Bostik or your wall cladding panel supplier for further information.

If the adhesive has not fully cured yet, the panel can still be pulled loose (with some difficulty). Clean the substrates: use a putty knife to cut away or scrape off the adhesive, remove the foam tape and clean the entire primed support structure with a cleaner. Re-apply the adhesive system (without primer, but with new foam tape and adhesive) once the substrate has dried.

Cut through the panel adhesive using a thin steel wire. Carefully remove the cured adhesive with a chisel, sand the substrate, ensure that it is free of dust and clean it with cleaner. Once the cleaner has dried, re-apply the primer, foam tape and adhesive in accordance with the instructions.
