Painting Bare Concrete Floors with Single Pack Floor Coating
(Recommended for light to medium foot traffic)
Two coats of paint are always recommended 1st coat primes and seals the floor. 2nd coat provides good colour build, protection and longevity of the coating.
Single Pack Floor Paints
When painting any concrete floor it is important that the moisture content of the concrete is no greater than 5%.Green concrete is best left for at least 2-3 months before coating. There are two main factors to ensure the single pack floor coating will offer the protection & durability you require. Any floor paint will require good floor preparation before coating. If time and effort is not but into preparing the floor before coating, then no matter how good a product is, or indeed how much it costs you to buy, the coatings potential will not be met.
With any floor coating preparation is an essential key to extend the protection and lifespan of the coating. To prepare a bare (rough) concrete floor prior to painting we always recommend a light abrasion first; this can be done either by a scarifying machine or track blasting (most effective method). This allows the paint to create a good lock and key effect with the concrete which then leads to much better adhesion.
If the floor has been power floated or is generally very shiny, the floor paint will not adhere to this surface. It is recommended to trackblast the concrete to remove most of the top layer prior to painting. The structure of the top layer in a power floated concrete floor is generally unstable and easy to damage this is due to one small partial size been pushed to the top. If trackblasting in not an economical scenario, you can use a scarifying machine or a concentrated Acid Descaler to etch the floor.
After the floor has been abraded, we then recommend degreasing the area, removing dust and anyyd a the floor.ing ical hed to the top layer unstable and easily damaged.
the Christmas holidays they know the pa loose parts. If floors are heavily penetrated with any sort of contamination it is important to remove it all before coating, the most effective way is to have the floor steam cleaned. Remember this will add moisture into the floor, so time will have to be allowed for the moisture to escape. If the floor has light or no contamination just a quick mop around with our Degreasing Solvent or Acid Descaler will suffice. Again ‘preparation’ is key for a good floor coating, should any moisture or contamination be trapped in the substrate the paint will simply blister and blow off.
Single Pack Floor Paint can be easily applied by brush & roller. Start to cut in the edges with a brush (use a good brush as this coating will start pulling bristles out of cheap brushes), then using our sheep simulated rollers or solvent resistant sleeves and tray, start to roll the first coat out; starting at the far end working back to the exiting door. Leave the first coat to dry for 12 hours or overnight before overcoating
