12 Concrete Floor Painting Tips

Posted in Firwood Hints and Tips by Firwood Paints Limited on September 30th 2019

1. Consider the Timings


Before beginning your floor painting project it is important to consider the timings involved. When using floor paints this is very important. Check the manufacturer's instructions to check on the length of the pot life, what drying times are expected, and then choose the right time for the application of the paint.

2. Don't Forget To Clean


Your floor may appear at a glance as though it is clean, but it will need cleaning thoroughly prior to the application of floor paint. Begin by sweeping and vacuuming the area before cleaning with detergent and/or a degreaser such as the Firwood 110 Cleaner and Degreaser. If you have any staining to the floor consider using a concrete etching fluid.

3. Use a Concrete Etching Fluid


The use of a concrete etching fluid such as Firwood 2709 Concrete Etching Fluid as a pre-treatment of concrete floors prior to application of floors paint to remove surface laitance is helpful when preparing floors for painting, especially those that are stained or are freshly laid and have surface laitance.

4. Sand the Floor


Concrete floor paint has better adhesion when applied to slightly uneven surfaces. That is to say that sanding the floor prior to application will help the paint adhere to the substrate. Etching Fluids are helpful in obtaining this uneven surface, but where necessary a range of tools can be hired to sand floors.

Floors that have already been painted would also benefit from sanding and the paint being stripped back before applying new paint to the flooring.

5. Eliminate Moisture


Eliminating moisture is critical to ensuring a high quality finish to the paint job. Seemingly insignificant drops of water or cleaning solution can lead to improper paint adhesion. Eventually, this will lead to a reduction in the protective properties of the paint.

A simple way to test for moisture on a concrete floor is to tape down some clear plastic sheeting, ensuring that it is air-tight, and leave it down for 24 hours. When removing the tape and clear plastic sheeting if you observe any moisture on the sheet or a darkening in colour of the flooring itself this indicates the existence of moisture within the floor and the floor will need further drying.

6. Deal With Imperfections


If your floor has cracks or damage then the paint job will also look uneven. Filling in cracks and removing any imperfections will help with the appearance of the paint job. It will also make applying the paint easier and more effective, including improving the longevity of the paintwork. Repairing the damage to the flooring will also reduce the risk of injury due to slips and trips.

7. Read the Instructions


Before beginning the work it is important to read the instructions as paint used for flooring varies in how it is prepared and applied from product to product. Always be sure to read the instructions provided by the manufacturer before beginning the preparation and application of the paint.

8. Use the Right Tools


Brushes and rollers are the most appropriate tools for the application of concrete floor paint. Rollers will help when you are covering the bulk of the flooring, whilst brushes allow you much more control for tighter spots such as corners and edges.

9. Protect Yourself


Ensure that the area is well-ventilated. Open all windows and doors, and where applicable run fans, though consideration needs to be made on what effect this will have on the paint job itself. Always wear suitable protective clothing such as goggles, gloves, and where required respirators. Naturally any clothing you wear should be something you don't mind throwing away after the job is complete. Animals should be kept clear of the area.

10. Start With the Edge


You may wish to apply masking tape where appropriate prior to commencing the paint job, but once you have done so starting with the edges is a sensible starting point. These are the more difficult areas to paint and will require a brush to complete the task.

11. Let it Dry


Not only during the preparation and application of the paint, but after it has been applied, you should take your time. Note the drying times on the manufacturers guidelines. Generally floor paints require at least 24 hours to completely cure and become fully dry to the extent where full foot-traffic can be allowed to cross over it.

12. Hire a Professional


Painting floors, especially larger floors with more specific requirements such as forklift traffic, is easy when you know how. If you are not experienced in paint application it may be a time consuming task and you may find that the work is carried out quicker and to a higher standard by hiring a professional to do it instead.

It is likely that with their experience the paint job will have a longer life as well, as mistakes, however insignificant they may seem, will be vastly reduced and thus increase the longevity of the paint job.
