Surface Prepration

a) Mechanical Sweeping & Wet Scrubbing

At Kenex, we offer a comprehensive range of services. To prepare your concrete surface, we offer sweeping and scrubbing, industrial concrete sealing and mechanical surface cleaning across Sydney and Brisbane. This particularly benefits new concrete surfaces such as basements where builder’s rubble and dust needs lifting.

We can then mechanically wet scrub the surface to leave it dirt and dust free in preparation for line marking and/or concrete sealing. Our wet scrubber drops water onto the surface, cleans with rotation nylex brushes, then vacuums excess water with a squeegee vacuum. This process eliminates costs associated with chemical purchases and reduces water wastage.

For outdoor applications, we also offer pressure washing to remove lichen, algae, and other dirt leaving the surface clean and with a slight key for optimum bonding of line marking paint/coating.

b) Shot Blasting

This method of surface preparation uses small pellets shot and blasted from the machine to remove redundant coatings, and etch the surface for new. This method is cost-effective and environmentally friendly.

The process is labour and time-saving as it strips, cleans and profiles simultaneously, leaving the surface immediately prepared for the application of new coatings or overlays. It eliminates dry time and costly disposal procedures associated with other methods. Shot blasting is a preferred method of preparation and is recommended by many coating manufacturers. It produces excellent bonding characteristics that promote maximum floor life and reduced coating failure.

c) Grinding

Grinding is another surface preparation method we used approptriate for smaller projects, areas difficult to reach with a shot blasting machine, and for applications which require a minor scuff to ready the surface for new coating.
