Preparation prior to Industrial floor coatings.
If the floor has been painted before there can be areas of defective paint, flaking, cracking and blistering. The existing coating can break down due to fork lift traffic or being scraped and overused in areas, leaving visual imperfections. To paint straight over these imperfections will not produce a lasting finish as any new coating is only as strong as the one it is sitting upon. Two part paint systems offer very high adhesion, however still need thorough surface preparation prior to application to produce long term lifespans.
This method of floor preparation uses rotating diamond tips to scrape away existing coatings, leaving a sound surface with improved ‘key’. These diamond floor grinding machines can be sit on or walk behind and some have build in hoovers to remove the loose coatings produced by the grinding.
Sand blasting/shot blasting-
Another method to prepare the floor is by means of sand blasting & shot blasting, especially effective around obstacles. This method is not as fast as diamond grinding but more suitable if flooring is breaking up and delicate with lots of obstructions.
Removal of vinyl tiles-
There are machines available from most tool hire shops that will speed up this job. Once the tiles are up there is still glue residue to be removed, grinding should remove.
If the floor has grease residue present it will need cleaning prior to painting, sit on or push along machines are available from hire shops.
