How to glue PVC?

PVC sheets can be glued easily, both PVC sheets and other types of plastic. In this blog, we provide information about the possibilities, the different types of glue and the processing methods. As with all other operations regarding PVC sheets, the sheet surface must also be clean and free of grease.

Gluing PVC sheets together

PVC sheets can be quickly and easily glued together with special PVC glue. Please note: the PVC adhesives from builders’ merchants are normally only suitable for hard PVC, such as in drain pipes. This adhesive is less suitable for bonding PVC sheet material. For this, you have to choose a so-called diffusion glue based on tetrahydrofuran, or THF. This glue is very thin and therefore less suitable for vertical glue joints but is ideal for gluing sheets. THF adhesives dissolve the surface so that the surfaces to be glued melt together. Due to the influence of light and air, the adhesive dissolves and the plates are fused together. This method of gluing is therefore also called cold welding. Make sure you work in a well-ventilated environment as the glue fumes are very harmful to your health. In addition, THF adhesives are highly flammable!

Gluing foamed PVC

Foamed PVC has top layers of cardboard, these can be glued with a normal contact adhesive. Foamed PVC can also be provided with a different top layer, a so-called veneering. The veneer layer can be applied to the foamed PVC (foam board) with conventional PVC adhesives.

Bonding PVC with other materials

PVC can be glued with a multitude of materials using the right adhesive. The necessary plastic adhesives and primers are available in our webshop. Below, we offer advice on gluing different materials:

Cardboard/paper: A standard contact adhesive or dispersion glue is sufficient for this. This gives a wet glue connection, the advantage of this is that the connection can still be corrected during drying.

Textiles and Leather: These materials can be glued with a standard contact glue or a dispersion glue.

Wood / Wood materials / Metal / Plastic / Drywall / Insulation boards / Ceramics: For this we recommend using a Bostik Superfix adhesive sealant. For a good adhesion of hard PVC, we recommend pre-treating the glue surfaces with Bostik Primer Prep M, while for foamed PVC Bostik Primer Prep K is the better choice.

Polystyrene: Contact adhesive, but a two-component PUR adhesive is better.

Stone / Brick / Concrete: For this, we recommend a Bostik Hightack adhesive sealant. For good adhesion of hard PVC, we recommend pre-treating the adhesive surfaces with Bostik Primer Prep M.

Always consult the instructions on the adhesive packaging and, if necessary, ask an expert to determine which adhesive is most suitable. Also take into account the application, the mechanical load and the temperature range of the environment in which the adhesive connection is used!
