Exactly how safe is Concrete Guard for a flooring surface? Print E-mail
The whole question of slip resistance is a good one and we will soon be preparing a dedicated information pack regarding this.  The short answer is that Concrete Guard has been professionally lab tested and is a very safe surface.

Here's a slightly longer answer.

More than one surface

Whenever you experience slip (or a loss of friction) there is more than one surface at play.  Think of a car driving on the road.  It's not just a case of the slip resistance of the road, but also the car tyres.  There are always two surfaces involved.

Surface texture

With concrete, the texture of the surface is what gives the grip.  Naturally, the rougher the surface of the concrete is, the better the grip will be.  Where you can get problems is with sealers that are merely a coating that sits on top of the surface.  These sealers cover up the texture of the concrete and replace it with their own smoother finish.

Concrete Guard does not present this problem as it is a penetrating sealer.  Unless multiple coats are applied, it will not affect the surface texture.  In the event that enough coats have been applied and Concrete Guard is the contact surface, you will still have a safe flooring surface.

Wet surfaces ....

If water is present on a concrete surface and you should experience slip, you might be surprised to know that you have not slipped on the concrete at all.  The truth is that you have slipped on the water.

How can Concrete Guard help?  Concrete is a porous material and will absorb fluids just like a sponge will.  An application of Concrete Guard will change the surface tension properties of the concrete such that water will not 'wet' the concrete and will run off instead.  Specifically, the surface tension of Concrete Guard will repel the water.

Going back to the example of a car driving on a road, good tyres that displace water quickly make it safer to go driving in wet weather.  Tyres that don't do a good enough job of this are not as safe and you would have to reduce your speed instead.  Slippage on a wet surface occurs only when the water can not be displaced fast enough for sufficient grip between the two surfaces to occour.

Concrete Guard has been lab tested with an "anti-slip coefficient" rating of 0.66 (possible range is 0 to 1).  Anything over 0.5 is regarded as being a safe surface.
