The Value Engineered Simplified-Polishing Application, VESPA Pad is designed to run from low to high speed, 200 to 1500 rpm. Caution should be taken on any surface with control joints, expansion joints, cracks, gouges, holes or deep scratches in the surface. Any height differential from one area of the slab to another can cause damage to the VESPA. Be certain to walk the entire area and address any differences in height with a hand grinder or floor grinder to level out any differences in slab heights. Deep gouges or scratches should be filled and leveled to the slab as well or damage can be incurred to the VESPA Pad.
Any nails, screws, anchors, anchoring devices, etc., must be removed or ground to the surface of the slab prior to running the VESA Pad over the surface.
The VESPA Pad is designed to be used wet or dry. When running the VESPA Pad wet, the surface should be saturated and continually kept saturated. The wetter, the better! The heat created with the VESPA Pad on dampened or misted surfaces will quickly turn the slurry into a thickened paste and the paste will gather on the VESPA Pad and can dramatically reduce the VESPA Pads effectiveness. It is recommended to thoroughly clean the pads after each use with water to keep the pad clear of buildup of slurry or dust.
When running the VESPA Pad dry it is recommended to use on a burnishing machine with an active vacuum system. Running the VESPA Pad at the lower grits can create a remarkable amount of dust. There are several models on the market, both propane and electric.
