Velcro sanding pads and failure to stay in place

One of the issues I have had with Velcro sanding pads is that if and when the pad comes off when sanding the action of the sanding will damage the hooks on the sander and the pad needs replacing.

I have a bench sander which uses stick on pads but when the sanding dust gets on the metal disk the stick-on sanding pads just don't stick.

SWMBO has a heat gun that s her fix it all tool so I may try the glue gun solution
 
I have a Lidl (Parkside) rechargable Hot Glue Gun ... I have various normal 240v guns and also a Modellers gun powered by 3S LiPo .... but that Lidl gun is simply - V good.

The problem with the Velcro is : Cheap sanding pads - the loop material gives out and pads slip ... if the pads are better and loop material stays good - the hook part on the sander 'flattens or just wears out' not 'hooking' the loop material
The Hot Glue solves BOTH of those situations ..
 
If the hooks on the disk itself are in decent condition, my experience is that when the velcro lets go, it's time to change disks. However, the hooks do get tired, and then it's time to change the pad. You can pay silly money for a proper Bosch one, or look on fleabay and buy a couple of imitations for a good bit less, which works for me.
 
You can buy a sacrificial velcro pad. It goes between the sanding disc and machines sanding pad. Much cheaper to replace than the machines disc.
Buy branded discs. Better velcro, they stay sharp longer and therefore less changing.
Cheap discs can have lousy velcro and go blunt very quickly.

Now all I need is a hot glue gun (and somewhere to store it, which is a major problem), and take it everywhere I need to do some sanding

I have had this problem from new on a Bosch multi-tool detail sander attachment. I was hoping for some more permanent solution to the problem.

On my old sander I used wood glue, any handy glue will do. Then with my new one (15 yrs ago) I learned not to run the sander too hot so now the Velcro lasts for ever.

Anyone tried brushing the pad with a stiff brush ?

Tried that ... it helps a little - but the basic thing is that the 'hooks' even with careful use and not pressing down on the sander - do wear out .... heat and wear is a factor that cannot be avoided ...

Its fine replacing the 'hook' pad - but it only gives a period before again needs replacing.

I have just sanded the whole rubbing strake of my 25ft boat .. Oak ... with ONE pad ... three blobs of Hot Glue and that pad stayed exactly in place throughout the whole job. The 'hook' pad was unable to hold the pad for more than a few seconds without.
On completion of the job ... I pulled off the pad and the blobs came with it ... leaving the 'hook' pad clean.
 
The problem with mine was that the holes in the abrasive sheet didn't coincide with those in the backing plate so the abrasive sheet got blown off. It was it was improved by making some extra holes with a screw driver but not enough. In the end I bought a new Bosch one for which I can get matching sheets. (My old one was a B and Q own brand).

I have a Parkside (Lidl) unit and a BESK set ... both I have difficulty finding correct pads for not only in size but holes for dust to pass via ...

The Hot Glue holds the pads whether I make own holes or not .... in fact I religiously made holes to match then one day forgot ... no difference.
