How To Fix a Factory Floor16/02/2021
Provided you are not using forklift, this has been found to be the most cost effective solution. In the old days as a thin coat solution we used to use either an epoxy or a polyurethane, but both come with problems. An epoxy is very hard, but brittle. It is also not UV stable. Polyurethanes tend to be more flexible but not as scratch resistant. Fairly new on the market is the Polyaspartic. It combines the best points of both epoxy and polyurethane and is a superior product. Here is an article about the advantages of a polyaspartic https://www.uscoatings.com/blog/polyaspartic-vs-epoxy-and-urethane-choosing-coatings-wisely/ Although it costs significantly more, we have virtually standardised on the polyaspartic from Specialised Coatings www.speccoats.co.za. It is the best we have used so far.
As you can see from the before and after photo’s this floor was in really bad condition before we started to work on it. The first thing we do is to grind down to clean concrete. This is very important in ensuring a lasting bond between the concrete and the resin.
Then all holes, cracks and divots are filled in with a great mixture from Samson Technologies https://samson.co.za/ It cures incredibly hard and can be worked just like cement. In fact it is more likely the cement will fail before this fails. We then do a final grind on the floor, using coarse, medium and fine diamond grits to end up with a good, smooth floor.
The floor is then primed with a Deep Penetrating Water Based Primer, again from Specialised Coatings (they make really excellent products)
After the primer has cured overnight we apply the first coat of polyaspartic (in either clear or the colour of your choice) by roller. This allows us to work it carefully into the surface, which results in an excellent bond between it and the concrete. It is allowed to cure overnight.
Then the final clear coat is sprayed over the first coat for added protection. You can choose either gloss or matt for your final finish, but we recommend matt as the gloss will eventually wear off, and then you have glossy and matt sections.
The floor can take foot traffic after 24 hours, but the product needs 10 days to reach full cure. Once it has full cure it is a virtually bullet proof solution for a factory floor.
