recommended that the floor be power washed with Zonex-KÒ Industrial Cleaner prior to
application of any materials. If
the floor is smooth and dense, it is highly recommended that the floor
surface be scarified prior to application of materials to assure a good
bond. Acid etching, sand
blasting or shot blasting methods can be used to scarify the surface.
In many cases proper preparation takes more time than actual application of the new material. Careful and thoughtful consideration needs to be taken into account during the inspection process. Write out the preparation steps as they will be performed. Sometimes looking at the job a second time will help the thought process to assure proper preparation. Should you encounter any unique type situations and are unsure as to the proper surface preparation please contact us for advice.
