SUITABLE FOR: Adhesion Promoter is ideal for use on all restoration jobs, especially those where the leather is heavily creased. In these cases, the adhesion promoter fills the creases so that when the colour is applied it doesn’t seep into them, instead, it will sit on top of the creases. Without the use of adhesion promoter in these cases, the colourant would fill the creases and run the risk of cracking out with use. The Adhesion Promoter should also be used on leather that you expect might be problematic, such as areas where grease/oil has been removed. The product will help the colourant stick better reducing chances of the grease coming back through and affecting the colour. It should also be applied to areas where the piping is raised out so that the leather is easily knocked and abraded with use. Applying Adhesion Promoter onto these raised areas will increase the lifetime of a repair suffering from heavy knocks and constant abrasion – areas such as car seat bolsters.

Improves the adhesion of colourants to leather & vinyl


Adhesion Promoter is a polyurethane liquid with extraordinary adhesive properties. Applied to leather or vinyl one step before the application of colourant, the product creates a flexible coating that binds to the leather surface. When the colourant is then applied, it sticks to the layer of Adhesion Promoter, rather than the leather.


Adhesion Promoter (creases)

This image illustrates how the adhesion promoter (in red) has filed the creases and formed a coating bonded to the leathers surface. The application of Colourant (black), then adheres firmly to this layer.


The adhesive properties of the promoter are much greater than that of the colourant, so applying it first, will create a better bond to the leathers surface than the colourant would have on its own. In addition to helping adhere to the leather better, the adhesion promoter will also start to bind with the colourant creating a permanent merged layer, rather than one sitting on top of the other.




INSTRUCTIONS STEP 1. Add 10% Cross Linker X to the Adhesion Promoter & shake very well for 2 minutes. The addition of Cross Linker X starts a chemical reaction with Adhesion Promoter increasing the adhesive qualities of the solution. It is also the addition of Cross Linker X that causes the bond to form between the Adhesion Promoter coat and the Leather Colourant. These images illustrate the adhesion promoter from a microscopic view. The image to the left shows the Adhesion Promoter without the Cross Linker. The image to the right shows how with the application of Cross Linker, the Adhesion Promoter bridges together bonding to the surface much better.   STEP 2.  Apply one base coat to the leather with a sponge ensuring it is fully rubbed into all areas. Dry off thoroughly with a hair drier so that the product has set, i.e. it isn’t runny/watery. The Adhesion Promoter will always dry tacky so the idea of the hair drier is just to set the product so that later applications do not run. Heat also starts off chemical reaction so each layer should always be heated with a hair drier. STEP 3. Apply two more coats by spray application using an airbrush. Apply one with a vertical movement and overlap this with a horizontal movement and dry off with a hair drier. Then another in a diagonal movement that overlaps, creating a crisscross effect. This ensures even coverage of the Adhesion Promoter onto the leather or vinyl surface. Use a hair drier in between coats to activate the product, after each coat the leather will become more tacky. Once mixed the product has a 3 hour shelf life. Apply Leather Colourant onto the surface immediately after Adhesion Promoter for best results.
