Diamond Surface Preparation
Why is Surface Preparation:
Floors are particularly prone to contamination because they are horizontal surfaces and act as the obvious catchment area for spillage of liquids or anything which falls and settles. Even on a new construction, splashes of paint, oils, plaster and mortar are common; not to mention dirt from foot traffic during the operation plus residues of curing compound used during construction. On existing floors, oil and dirt are common in production areas and other materials may have penetrated the concrete surface over long period of time.
New concrete floors
A first-class, well finished and well cured concrete floor slab may need little preparation other than sweeping or, preferably vacuum cleaning. The use of an industrial vacuum cleaner is always the first choice if is available – as it removes the dust progressively, unlike sweeping which always deposits some dust on previously swept areas.
The most likely problems, if they occur, are surface laitance, plaster for mortar splashes and residues of applied curing compounds. The common choice for surface preparation in these cases is between acid etching and sweep blasting.
Old concrete floors
It will be very rare indeed when an exiting floor which has been in use for some time will not require preparation by cleaning. Indeed on most occasions when a floor has been subjected to a degree of attack whether chemical or mechanical, sufficient to cause enough of a problem for Delta Misr to have been called in then it is almost inconceivable that the floor in question will be suitable to receive a Delta Misr product without prior preparation.
Proprep" Planning & Grinding System
It use of floor planers or grinders is ideal for removing surface contamination and laitance. These machines can be fitted with industrial vacuum cleaners, the most modern of which are specifically designed to deal with even the finest concrete dust. The finished surface texture can be varied by careful choice of cutting tools.
