2nd year on a flat roof without slope with water remaining on the roof for days, it has not shown the slightest issue. The secret is the correct application of 2 hands of primer, 1 horizontal and 1 vertical, and then the Isomat hybrid. Also, something very important: before applying the material, the area where it will be applied must be spotless for better results.

Perhaps the most value for money insulation available on the market. 3 years after 2 applications in 2019 and it still remains intact on a 100sqm terrace, pure white and elastic...
Bravo to Izomat, a truly Greek exemplary company

Very good choice for waterproofing the terrace (without insulation), always with the corresponding primer first. In very positive or temperature difference, it is 3 degrees cooler inside the house in the summer, but also in the winter with the cold. Time will tell how durable it is, this year will be the third winter and the condition of the material is very good. Very good technical support from ISOMAT.

The terrace was cleaned with sandpaper before application.

I personally applied it over a tarp, which turned out to be a bad choice. Obviously, first I applied a primer underneath and then used a roller and a brush in difficult areas. I consider it to be thicker than the regular and cheap ones, and I hope it will last me for 4 years, I will be satisfied. Then again, I will repeat if everything has gone well, I am not experienced in these things but it seems like a good choice.
