Painting Floors from Promain Paints

When painting concrete floors, you need to ensure the preparation is of the highest quality.  The existing coating will need to be removed, or identified, cleaned, abraded and degreased.

Recently installed concrete floors will need to fully cure and preferably be grit blasted to remove the laitance, for smaller projects.  An acid etch treatment is a popular solution.  In most cases, the first coat of floor paint is thinned to assist with impregnation into the concrete and allowed to dry.  Apply the second coat neat then allow the system to fully cure.  To create a slip resistant surface, anti-slip aggregate can be sprinkled over the first coat, and then sealed in with the second coat. Use of a double armed roller frame holds the roller at both ends, and allows equal pressure across the width of the roller.  Using a paint scuttle allows you to cover the entire surface of the roller and helps to avoid a patchy finish once the second coat has been applied.  Often, the first coat can appear patchy due to varying porosity of the substrate, so don’t worry at this stage.  It is important that the paint is left to fully cure before it is trafficked, otherwise unwanted scratches can occur.

What is the correct paint to use?

You will need to choose an appropriate paint for the type of surface and environment.
For a workshop floor where there is foot traffic and storage etc. Promain offer Rustoleum 7100 which is an easy to use product and can also be applied to wooden floors.  This is also available in a pre-mixed anti-slip version for enhanced slip resistance for designated walkways etc.

Used on bare wood or clean concrete more than two years old, simply thin the first coat with 10% white spirit and apply the second coat neat.  This product can be applied over most existing floor coatings, however, a trial area is recommended to ensure compatibility.

Industrial Warehouses

For an industrial warehouse storing food items and where fork lift and palette trucks are used, Pegakote two pack water based epoxy is a good choice.  Offering a semi-gloss appearance, this product offers excellent abrasion resistance, chemical resistance and low odour.

The hardener is mixed in with the paint and paddle mixed together prior to application.  This initiates a chemical reaction where the paint cures and becomes very hard wearing, reaching full chemical resistance after 1 week.

The standard range of colours are readily available, but we have the ability to tint to a wider range of colours if required.  This product will need to be applied to grit blasted concrete, or the use of 108 surfa-etch for smaller jobs, where you will need to rinse the floor abundantly with water and allow to dry. Thorough rinsing avoids creating an acidic concrete, which can damage the paint.

Anti Slip

External areas subject to light foot traffic can be given an anti-slip coating such as Coo-Var Suregrip, but you may need a primer depending on what surface is being painted.  For wood, use the P224 wood primer.  If you are painting onto concrete, use the G136 floor paint thinned with white spirit, followed by two coats of Suregrip.  To ensure an even distribution of anti-slip aggregate, stir the paint before and during application, otherwise it can sink to the bottom of the tin. This product will need to be applied to grit blasted concrete, or the use of 108 surfa-etch for smaller jobs, where you will need to rinse the floor abundantly with water and allow to dry. Thorough rinsing avoids creating an acidic concrete, which can damage the paint.

At colder times of the year, the SigmaCover 640LTNS offers curing at low temperatures and provides non slip surfaces for external concrete and metal surfaces, which often need maintaining in the winter months. SigmaCover 640LTNS  is surface tolerant, meaning that manual preparation is sufficient in order for this product to adhere; however, oil and loose material will still need to be removed.
