A Crash Course in finding the best Floor Paint for your Industrial Area!

As we all know, there are hundreds of manufacturers and thousands of suppliers. Furthermore, most people have had many disappointments with their chosen floor paint, whether it be a case of bubbling, delaminating and/or simply not lasting.

Here, I’m going to give you a crash course in some basic facts that will highlight points that you may never have known or even considered before and help you to make the best decision for YOUR needs.  I’m going to highlight three main products/options and tell you the differences/benefits of each and then I will show you the price differences for a theoretical 120sq.m floor area and leave you to make your own choice.

The three products to be considered are:

PB Floor Paint, a single pack polyurethane floor paint

Flortex SG, a water based twin pack epoxy floor paint, and finally…

Flortex Professional, a twin pack 100% solids pure epoxy floor paint.

Option 1: PB FLOOR PAINT. A single pack polyurethane floor paint

Example: 120sq.m floor area.  Applied at 30sq.m per 5L unit = 4 tins. Two coats required = 8 tins

8 x 5L tins @ £76.45 each, equals a total cost of £611.60. Price per sq.m = £5.10

A single pack means that it can be applied directly from the tin. Most single pack paints are either water based, or solvent based, and they cure atmospherically. In other words, the water or the solvent evaporates into the atmosphere and as it does so, leaves the ‘solids’ of the paint to cures to a final ‘hard’ finish. Due to this evaporation process, this can leave a micro porous finish which then means that liquids such as water and oil can penetrate through the paint and thus, over a period of time, the paint delaminates from the floor.

In industrial areas where oil is present, this creates an even greater problem as the oil that has seeped through into the floor substrate below, then prevents any other subsequent paints from sticking. Bacteria loves a micro porous finish, and this is one fundamental reason why single pack paints are not regarded as suitable for kitchens or any other food production or processing areas. For any of the above- mentioned areas, a twin pack epoxy is strongly recommended, as follows:

Option 2:  FLORTEX SG. A twin pack, water-based epoxy floor paint

Example: 120sq.m floor area.  Applied at 30sq.m per 5kg unit = 4 tins. Two coats = 8 tins

8 x 5kg units @ £115.85 each, equals a total cost of £926.80. Price per sq.m = £7.72

First and foremost, epoxy resin is one of the world’s strongest forms of adhesive and a twin pack epoxy floor paint (supplied in two parts, a base resin, and a hardener) is one of the strongest floors with the best adhesive qualities.  The second important point is that due to twin pack formulation. When mixing the two parts together, the paint cures by way of chemical reaction (rather than simply atmospherically) and this leaves a totally impervious surface from above.

So, when spilling liquids onto the floor, they do not get ‘into’ or through the paint and therefore, not only is your substrate fully protected but also your cleaning routines are far easier that when using a single pack (micro porous) paint.  Due to being impervious, this also helps to reduce smells in areas as any offensive liquids (especially in washrooms, toilets, animal house, pens, etc) do not seep into the paint/substrate.

So, in summary, for an extra £315, Flortex SG will adhere far stronger to the substrate, will far outlast a single pack floor paint as well as making the area easier to clean, meet health and safety requirements for food areas and finally, offer a more pleasant and less odourous place to work in / visit.

Option 3:  One coat of WD Primer and One coat of Flortex Professional.

Example: 120sq.m floor area.

WD Primer, applied at 30sq.m per 5kg unit = 4 units. £96.90 per 5kg unit = £387.60

Flortex Professional, applied at 40sq.m per 15kg drum = 3 drums. £218.90 per 15kg drum = £656.70

Total price for both coats = £1044.30. Price per sq.m = £8.70

Firstly, I want to make clear that Flortex SG is both an excellent floor paint and also a very popular choice of our customers. Furthermore, it has been laid over millions of sq.m since our inception in 1991 and has been proven in almost every type of industrial and commercial environment. However,…!

All professional painters prefer to apply a ‘professional’ primer before applying a top coat. The reason for this is that they are manufactured with adhesion promoters and have better penetrating abilities into the substrate due to being less viscous. The higher viscosity of the top coat is mostly due to pigment clays and high build fillers included within the paint.

WD Primer has been professionally formulated with advanced adhesion promoters and has incredible adhesion to most surfaces including concrete, stone, terrazzo, and even ceramic and quarry tiles! We completed a pull off test between WD Primer and a ceramic floor tile. The primer did not pull off the tile before the tile itself shattered!

Flortex Professional has also been professionally formulated for ultimate strength and wearability.  It has incredibly high impact, abrasion, and chemical resistance.  It has been proven on over 2 million sq.m in some of the most demanding environments.  We have sites where this system has been in constant use for 10, 15 and even over 20 years, and still going strong.

So, which one is for you?

If you already know that you are looking for a twin pack epoxy coating, lets now consider the difference between Option 2 (two coats of Flortex SG) and Option 3 (WD Primer and Flortex Professional).

First and foremost, Flortex SG and WD Primer are the same base resins. However, when pigment (colour) is included within a resin (Flortex SG), it reduces its priming capability. Basically, the pigment obviously does nothing to help it stick to the surface and by including it, the product becomes ‘thicker’ and therefore reduces its ability to penetrate the substrate.

The adhesive qualities of WD Primer are so much greater because instead of adding a pigment, we include advanced adhesion promotors to really make it stick, so much so, it can adhere strongly to ceramic and quarry tiles, never mind the usual materials such as concrete, wood and stone. When all is said and done, the very first coat is actually more important than any subsequent coat, simply because if the first coat doesn’t adhere well, no matter what you apply over the top, everything is relying on the adhesion of the first coat. And ultimately, this is why so many coatings fail.

Other differences

Now that we have made it clear as to the first coat, let’s look at the differences between the top coat using Flortex SG as opposed to Flortex Professional.  Here you will see, the difference is massive!

When applying a water based resin, you need to know the solid content, which then tells you the water content. Let’s just say hypothetically it is a 50% solids resin (which is quite a popular percentage) this then means the product is around 50% water. If this is indeed the percentage, what no salesman will ever make clear to you is that 50% of what you are buying is going to evaporate and leave you with on 50% of what you have bought on the floor.  Therefore, if you purchase a 5kg unit, you only end up with 2.5kgs on the floor!!!

Flortex Professional is a 100% solids high build epoxy coating, frankly the best you can get.  And when you apply a 15kg unit onto your floor, 15kgs STAYS on the floor.

So back to our example area of 120sq.m, and just considering the difference between the two topcoats, for Option 2, you would buy 4 x 5kg units of Flortex SG (a total of 20kgs) which would leave 10kgs of cured material on the floor. For Option 3, you would buy 3 x 15kgs (a total of 45kgs) whereby the whole 45kgs STAYS on the floor.


In summary, with Option 3, not only do you get a FAR better first (priming) coat, but the top coat ends up 4.5 times thicker and will therefore last many times longer that Flortex SG. And the coat difference…?  Only £117.50 or 98p per sq.m.

Now you can make you own informed choice. A floor that is over 4.5 times better for less than a quid extra per square metre! Respectfully speaking, it’s a no-brainer!
