Description
Ardex PC-T 4 Polished Concrete Topping is a rapid-drying, cement based compound for creating polished concrete floors. It is walkable in 2-3 hours and can be polished in as little as 24 hours.
Ardex PC-T 4 Polished Concrete Topping comes in 25kg bags.
Ardex PC-T 4 is for internal use only. It can be used in retail stores, schools, airports and all areas where a fast track, polished concrete surface is desired. Ardex PC-T 4 can be installed from 10mm up to 50mm neat over large areas, and up to 130mm with the addition of a suitable graded aggregate. To benefit from its levelling properties it should be applied at least 15mm thick. When applying at thicknesses of over 30mm, larger aggregate may be incorporated.
Ardex PC-T 4 wear surfaces are intended to replicate traditional polished concrete and as such will not be perfectly homogeneous in appearance. The physical act of spreading and smoothing, along with the polishing process, will result in optical variations in the appearance of the floor even though it is very flat. Variations in the overall finished appearance are an intended effect and should be expected.
The finished polished surface should be protected, to minimize the risk of staining, from spillages such as oil, salts, water, etc., by applying a suitable sealer and/or stain protection system.
Ardex PC-T 4 wear surfaces are intended for foot traffic, rubber-wheeled forklift traffic and similar uses. Excessive service conditions, such as steel or hard plastic-wheeled traffic or dragging heavy metal equipment over the floor, will cause gouging and indentations.
As with any decorative floor covering (wood, soft natural stone, marble, etc.), allowances must be made for scratches or abrasion that occur due to moving or sliding furniture or fixtures over the surface. The fitting of soft felt pads is recommended for furniture/fixtures that are moved frequently. Keeping the floor surface clean and free of dirt or other contaminants will also help to minimise scratching and scuffing of the finished surface.
Coverage:
Approximately 1.87kg Ardex PC-T 4 powder/m2/mm, e.g., one bag will cover approximately 1.3m2 at 10mm thickness. NOTE: The coverage figure is based on a flat level surface, additional material should be allowed for where the surface is rough or uneven.
