When painting concrete, paving or areas that have a slope to them, it is important to think of how slippery the end result will be. A paint will generally be more slippery than a concrete, paving, or natural stone surface. Before painting a slope, use this guide to determine how steep your slope is.
You will need a measuring tape and a spirit level to do this.
Measure the length of your spirit level (not the distance of the surface you are painting). A standard size is usually around 60 cm.
Now, place one corner of the spirit level on the slope, and hold it level. The end that isn't touching the ground should be anyway between a few centimeters and 15 cm from the ground. See diagram below.
Using your tape measure, measure the distance of the drop. That is the distance from the ground to the bottom of the spirit level.
Calculate the slope by dividing the drop by the distance, both in centimeters.
For example, if the length of my spirit level was 60 cm, and my drop is 5 cm, my slope would be 5/60 = 0.083
Now you can choose what Berger Jet Dry product is suitable for the slope.

Make sure that you are using a product the is suitable for the area that you are painting.
