What are the rules for applying a peel & stick product?

It is vitally important when laying a peel & stick product that the surface is thoroughly cleaned to remove any grim or dirt. We use a wax and grease remover. If you use a product such as methylated spirits or turps, as these are oil based, they will leave a residue that can affect the bond. Use a isopropyl alcohol (wax and grease remover) to remove this film.

Peel & stick products adhere well to metal surfaces, however if you are sticking the product to porous or rough materials, such as factory bitumen sound deadener, the product will require additional Spray Adhesive. 

Peel & stick products should not be stretched when applied to a surface as the material will eventually want to 'pop' back.

You need to ensure that peel & stick products are thoroughly rolled down, with pressure applied across the entire product to ensure that it has firmly adhered to the surface. We use an Application Roller.

If you find an air bubble, you should pierce the bubble to release the trapped air and roll the product down firmly.

We recommend using additional spray adhesive when using products in inverted positions or if you are directly adding further weight onto the product, such as glueing 4-way stretch carpet to the product's surface.
