Surface preparation is a critical factor in the success and durability of coatings. Most of the debonding or coating failure is caused by improper or absent of surface preparation. For example, epoxy can excellently adhere to concrete, but not to oil or grease. If oil or grease, which has penetrated into the concrete, has not been removed thoroughly beforehand, the installed coating would soon peel off.

Surface preparation means making the surface ready for maximizing adhesion with coatings. It includes removal of substances affecting the adhesion, changing surface texture, minor repair of damaged surface, etc.

Chematco believes that investment in surface preparation equipment is a must for a professional coatings installer. We are a distributor for CONTEC of Germany and are equipped with a full range of equipments from CONTEC, a worldwide supplier of professional surface preparation equipment.

Dust-free Shot Blasting is one of the preferred methods. With the help of Dust-free Shot Blasting Machine, substances affecting the adhesion (including adhesive, grease, laitance, loose particles, contaminants, and floor paint on the floor or concrete) can be removed easily and effectively.

After shot blasting, the texture of the surface appears as medium-grit sandpaper, which can physically maximize coating adhesion.

Minor repair of the damaged areas with epoxy mortar provides a strong and level foundation for subsequent coating.

Surface preparation maximizes coatings adhesion to substrates physically and, chemically. Moreover, it improves the outlook and durability of coatings. If you are selecting the right installer for your coating projects, pay extra attention to their knowledge, skills and equipment in surface preparation.
