Clean n Etch 5L - This product is made for very smooth / power floated floors or dirty floors. Clean N Etch is a highly concentrated blend of non-fuming acidic compounds and cleaning agents, specifically developed to prepare concrete floors prior to applying paints and other protective coatings.

Step 1: Floor Preparation

How to paint garage floor – Step 1: The concrete floor was a relatively clean surface and was not power-floated, so did not need a clean and degrease nor clean and etch. The floor just needed a brush and hoover to remove the surface debris and dust. If your garage floor is showing signs of ingrained oils or grease, we recommend that you use Regal Clean and Degrease to prepare the floor prior to painting. If your concrete floor is overly smooth or power-floated, we recommend that you use Regal Clean n Etch to open the pores of the concrete and allow the paint to absorb into the substrate.

It’s hardwearing surface gives good protection against corrosion due to it’s zinc phosphate content. Two-Pack Epoxy Metal Primer is suitable for galvanised steel and aluminium. - Coverage: 5-10 m² per litre - Touch Drying Time: 12 hrs - Recoat: 24 hrs - Hard Drying Time: 48 hrs - Full Cure: 7 days

Step 2: Two-pack epoxy primer

How to paint garage floor – Step 2: The customer used 5 litres of 2 pack epoxy primer – this is usually a red or pinky colour to contrast with the topcoat. Epoxy primer is thinner in viscosity to the topcoat, so that it is able to soak down into the concrete, penetrate the concrete. The base coat is anchored in the concrete, not just sitting on the surface. Epoxy primer dries with a flat (matt) and porous finish – if you could at a cross-section of the dried primer under a microscope, it would look like peaks and trough. This is purposefully designed so that the dried surface-area will readily accept a topcoat, to lock into those peaks and troughs, giving good intercoat adhesion.

Step 3: Two pack Epoxy Floor Paint (Top Coat), Paint Mixer

How to paint garage floor – Step 3: The customer used 5 litre of 2 pack epoxy topcoat in slate grey. It is very important that you use an epoxy top coat with an epoxy primer because they are both made on the same resin system (the coats cross-link well, giving good intercoat adhesion). An epoxy topcoat is an extremely hard-wearing product. It is important to allow epoxy paint to have the recommended induction period (sweating time) after mixing and prior to use.

Painting tips on how to Paint Garage Floor

The paint is poured directly onto the floor and a roller is used to spread the coating, rather than using a tray. When painting floors, rollers trays are unnecessary – they are time consuming and you may find that an epoxy paint starts to dry in the tray, creating flakes of dry paint which you then mix with the wet paint from the can. You only really need to use spiked shoes if you need to access areas by walking over the wet paint. On such large area, we would recommend rolling the paint onto the floor in approx. 3x3m sections – roller in one direction and then re-roller having rotated your position by 180 degrees (this will help to alleviate roller marks).

This customer then sprinkled a glitter over the wet paint, (please note – we did not provide the glitter). If using a glitter, do not mix it into the paint as it will just turn into lumpy paint (the glitter will just get covered in the paint), rather sprinkle it over the top.
