  • Does it spread easily?
  • Value for money
  • Does it dry relatively quickly?

What do users say? AI-generated summary

Users find that it provides effective waterproofing and appreciate its easy application and good adhesion. It is often mentioned for terraces, where it can cover cracks, maintain its white color, and help keep the home cooler; some users also note that it holds up over time. However, it requires a primer and usually 2–3 coats, and it must dry for several days before being exposed to rain. Some consider it expensive.

  • This review is about the capacity: 10 lt

    Easy to work with; you need 2–3 coats for it to do a good job. WARNING: To withstand rain, it needs at least 5 days to dry thoroughly. After the 24 hours stated before recoating, it hasn’t dried properly and won’t withstand rain—it will weaken. Check the weather forecast and give it time to dry!

    Top waterproofing product along with Isomat Isoflex Hybrid, always combined with a primer specially designed for this category of insulations and polyester fabric for perfect results and to have the 25-year warranty provided by Vivechrom.

    I have done my terrace with Isotop and I think it is a very good product. It has been 4 years (I check it every year) and it is going well. If I see that it starts to wear off, I will apply another coat on the terrace. I think I will do it next year regardless, whether it has wear or not. (I will reinforce it and use much less material, so it will be more cost-effective for me)

    Clean the terrace as well as we can (I did it myself to save money) and then apply the Waterproofing in a cross pattern. One coat vertically, one horizontally.

    It is better to do this AFTER the summer and BEFORE the rains.

    One pot covers a roof of 40m2 and approximately 20% remains in the pot.
    Very satisfied with the lower temperature in the house, especially at night

    I was waiting to see how it would perform with the first rains and cold weather... PU in general is much better at this price, it doesn't get dirty as easily as older insulation technologies, it also maintains whiteness for longer and has better breathability.
    I highly recommend it, don't bother with cheaper insulation for a few euros...
    Also, the reapplication on top of older insulation worked very well, no issues.

    Expensive but gets the job done. Definitely need a roller underneath. Then it spreads incredibly easily. Two hands on 35 square meters and had 1/4 left over.
