Surface Preparation
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.
How does Surface Preparation help?
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.
