The most overlooked condition requiring surface preparation is the condition before repainting markings. Airfield markings are exposed to all of the worst elements: rain, heat, extreme cold, chemicals, heavy loads and/or infrequent use, ultra violet light, algae and other stresses. Each element can individually stress the markings on the pavement; but in combination, they can result in the marking materials becoming aged, faded, brittle, cracked and worn. Removing the existing layers affected by such elements gives the new coating a better surface on which to bond.
Contaminants which can affect coating adhesion include, but not limit to:
• Cure compound (new concrete)
• Loose, flaky or poorly bonded materials
• Rubber deposits
• Oils, fuels, & jet blast
• Mold or algae
Hi-Lite realizes that proper surface preparation is the most important thing you can do to assure the quality of your paint job. Up to 80% of all coatings failures can be directly attributed to inadequate surface preparation, which affects coating adhesion. That’s why Hi-Lite has invested heavily in a fleet of the hydroblasters, vacuum recovery sweepers and rotary brooms.
Hi-Lite’s proven methods, modern equipment, and professional technicians, offer high production rates, as well as cost-effective and environmentally friendly results, while setting new standards of excellence in surface preparation.
