For the refurbishment and deep restorative cleaning of hard floors, The Preparation Group, specialists in providing solutions for preparation, maintenance and finishing, offers the multi-tasking STG450 and lighter STG400 machines.
Both have a wide range of attachments that can be fixed or simply placed under the machine to grind, sand, key, clean or polish; resin, terrazzo, marble, natural stone, wood, concrete and vinyl:
Nylon Brush Plates scrub and clean old floors to remove surface contaminants. Nylon is flexible and so lasts longer than polypropylene equivalents. This plate can be used with cleaning products or degreasing solutions but water gives an environmentally friendly clean.
Standard Drive Plates are fixed to the STG machine to enable attachment of the following range of discs and pads:
Tungsten Carbide Copper Discs are available in 3-36 grit. The coarser grades are aggressive for the removal of old adhesive residues and paint. The finer grades can be used for medium to heavy sanding of wooden floors.
Black Sanding Discs are available in 16 to 120 grit and are for light to medium sanding and grinding and will remove surface contaminants and key terrazzo tiles for overlaying.
Scrubbing Pads in Coarse, medium, fine and buff are for general cleaning operations like removing floor wax, ground-in dirt and scuff marks.
Mesh Discs are available in 60-180 grit and can be used to remove and key varnish for recoating and for the final sanding of wooden floors. They will also lightly sand hard, dense materials such as epoxy coatings and screeds.
SFD’s (Surface Finishing Diamond Pads) available in 50 to 3000 grit, are for chemical-free deep cleaning, renewing surfaces and a first-time polish on hard floors.
They are the only system capable of grinding, cleaning, keying, texturing, sanding and polishing the surface without clogging. The pad grades can be used in sequence as a staged polishing process.
Storm Diamond Pads are the only double-sided diamond pad currently available for twice the value and in 400 to 3000 grit for deep cleaning and maintaining previously polished smooth, hard surfaces.
They remove light scratches and staining and can leave a soft sheen or high gloss finish depending on the grades selected.
A hygienic, shiny, yet non-slip floor on hard floors is achieved just by adding water. Again, it is a staged polishing system involving working up the grades to the desired finish.
Other plates and discs are available for heavy duty preparation work such as a complete floor renewal.
Two recent projects carried out by The Preparation Group’s contracting division, PPC:
Removing screed laitence
Project: To sand 3,500m2 of calcium sulphate screed for a Care Home in Harrogate, to remove the surface laitance so that new tiles could be laid.
Equipment: STG450 attached to a M450 vacuum for a dust free operation and fitted with a 24 grit TCT Copper disc.
Result: The area was completed in one week, ready to receive new tiles.
Project: To polish a 40 metre concrete slab that was uneven and pitted, in the reception of a University building.
Equipment: The slab was ground with the Terrco 3000 multi-head machine to remove the high spots, flattening and smoothing the area. The polishing process was then completed with the STG450 machine fitted firstly with SFD’s, working up the grades from 100 to the finest 800, followed by Storm Pads used with water.
Result: A shiny, yet non-slip concrete floor, with Storm Pads purchased by the client for its on-going maintenance.
