Velcro sanding pads and failure to stay in place

[Refueler]

I have had problems getting sanding pads to stay in place on Velcro base sanders ... then I decided to look at replacing the base Hook sheet on the sander.

Youtube provided a solution that is so simple and it WORKS !!

I applied 3 dabs as the guy shows .. and problem solved.

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.

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

Usually only have this problem with cheap disks. I now cut my own from a roll of the mesh type abrasive like Abranet, better sanding and dust extraction.

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 ..

That's fine as long as the base pad on the sander is still good ... but the 'hooks' flatten out and fail to 'grab' ....

I just replace the hook sheet when it wears out.

I am too tightfisted to buy a new pad for my mainly festool sander

Usually you use an interface pad between the sander and the disks, Mirka do good ones, then the only velcro that gets worn is on the interface pad rather than the sander

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.

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.

I buy a sheet of hook Velcro, remove the old hook sheet and glue the new one to the old backing pad. I'm cheap as well!

Yes,

If you let the sander, or the pad, get too hot the Velcro melts, or at least deforms such that it does not grip itself.

Anyone tried brushing the pad with a stiff brush ?

 

[Daydream believer]

I loaned my sander to a friend & he knackered the velcro immediately, because he did not know that he needed to add a sander pad. He thought the velcro hooks were a sanding medium on the sander.

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.

Problem is even with care - heat and wear are inevitable ... its all part of sanding ...

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.
