MudMaster - Drywall Mixer

The De Wall Mudmaster

Mudmaster Drywall Mixer

The De Wall Mudmaster is 'One of Kind.'

Designed by a skilled craftsman with years of experience in drywall construction.


Take the work out of mixing mud.

Mixes by slowly folding the mud without aerating. Drywall mud is near perfect every time.

Cuts labor costs. The De Wall Mudmaster does the mixing while you keep working.

The De Wall Mudmaster has a covered tank, no messy splashing while mixing and no dirty buckets to clean. The covered tank prevents the mud from drying out. Daily cleanup is eliminated; mud can stay in the tank for long periods of time without drying up.

The De Wall Mudmaster mixer avoids the back and shoulder problems associated with mixing mud with a drill or stomper, hauling mud buckets and manual pumping. Mixing and pumping mud is hard work. To apply 20, (500 foot) rolls of tape, 1000 strokes of a manual pump are required and about 20 boxes of mud have to be mixed. The Mudmaster drywall mixer eliminates that time consuming labor. It can also reduce the likelihood of repetitive action/strain injuries from mixing tasks.

The De Wall Mudmaster mixer makes work more pleasant by eliminating boring, labor intense, repetitive tasks. Add the Washmaster for even more labor savings and faster, easier drywall clean up.
