Contour Sander – Sticky, Adhesive Discs Not Quite Sticking?

 

Are your Sticky Sanders flying off of your Contour Sander mid use? If you are a user of the adhesive disc method then you are probably well aware that the adhesive discs perform best at finishing sanding. We recommend heavy sanding with the heavy duty discs followed by the adhesive discs to remove any scratches left from the flange of the Heavy Duty Discs.

 

The trick to stopping the Adhesive Discs from coming off of your Contour Sander is to keep the backing pad clean. We have provided past methods of cleaning your Arbortech Contour Sander pads with acetone, cleaning spirits etc. Here is a quick and easy way to clean your Contour Sander’s backing pad using a rubber eraser or if you are short an eraser – your thumb!

As you know, the Contour Sander is ideal for sanding internal curves and contours by utilizing adhesive backed sanding discs. We have received many questions as to why we opted for this method. The reason is simply because the Sticky Sanders allow you to follow profiles nicely, and this also eliminates the problems experienced with the hook and loop method.

Adhesive residue on the rubber pads

 

When you are continually changing the adhesive/ sticky sanding discs, a certain amount of adhesive tends to build ups on the rubber backing pad. Where there is a combination of adhesive and dust accumulation on the backing pads it can prevent adhesive discs from sticking properly, so your discs will tend to come off too easily.

Previously Kevin recommended you simply wipe down the rubber pad using acetone or paint thinners but not everyone has these materials on hand. Since then Kevin has found it is much more convenient to simply rub the adhesive disc with your thumb; which works particularly well if it is warm from use.

 

Rub the pad with your thumb

 

You can actually roll the adhesive off the backing pad with your finger. This is a convenient method unless there is too much adhesive build up. Then best option for this scenario is using a standard soft pencil rubber eraser.

 

Use a normal soft rubber eraser

 

Put the eraser into a vice and then bring the Contour Sander backing pad into contact with the eraser while it is running. Within a few seconds it will rub off the adhesive build up very quickly. When you are mounting the eraser into the vice, the trick is to mount it very low so only a centimeter or so is above the level surface. If the eraser is protruding to much, it will simply vibrate and break when you bring the Arbortech Contour Sander into contact with it.

 

Mount the eraser in the vice and run the Contour Sander over the eraser

Now place your Arbortech Contour Sander over the eraser and switch your grinder on. The eraser will pull the adhesive off the Contour Sander’s backing pad quite easily and leave it nice and clean. If there is still adhesive on the pad, just repeat the process until you are satisfied with the end result. Once the adhesive has been completely removed off the Contour Sander’s backing pad, you can attach a sticky adhesive disc onto the backing pad and get back to sanding!
