2 years on a 120 sqm terrace in a summer house 200 meters from the sea with a lot of humidity in the area. I cleaned the terrace well and applied 2 coats in a cross pattern and one more in areas that receive water and in the joints of the tiles and near the drains. So far, it doesn't seem to have any issues. Next year, I will wash it and apply another coat. I hope it holds up. That's how it looks anyway.
In the end, this year it's fine. I won't apply another coat for nothing. We're in the third year and it's okay.

Excellent product. I cleaned the terrace thoroughly with a pressure washer. I applied the first coat diluted enough. Then I applied three coats crosswise. WARNING: BLACK SUNGLASSES ARE NECESSARY because it reflects the sunlight and it is dazzling!!! In the summer, with the sun burning at 3 o'clock in the afternoon, you can touch the surface with your hand and it is cool... excellent!

It has been 5 years and all I do is clean it with a rubber every summer to remove the dust. I highly recommend it

I confirm as well.
Very good product. I have coated my terrace and the result lasts for 5 years now.
Having previously treated the terrace with a waterproofing primer. This year, I am planning to recoat it again after washing the terrace with a pressure washer.

Incredible resistance to sun and wear, I have placed it on the balcony, a mosaic of about 50 years, 100 square meters, with many pots that we drag, and the insulation doesn't get damaged at all. Every 5 years, I wash it with a pressure washer and repaint it. I don't dilute it, I mix it very well with a mixer. I hope I helped
