How much waterproofing is required to cover a slab or roof?

It depends on the IMPAC presentation you are going to use, as the spread rates vary.

First you need to measure the length and width of the slab or roof to be waterproofed (taking into account all the parapets, they also have to be coated.

Later, check the spread rate of the IMPAC waterproofing you plan to use (the waterproofing spread rates vary, depending on the type of waterproofing and the roughness of the surface).

Do I need any other material to apply waterproofing?

Yes, it depends on the presentation of IMPAC you are going to use, the products may vary, depending on the system you choose. Generally acrylic waterproofing requires an acrylic seal and an acrylic plastic cement and, on some occasions, reinforcement fabric (most of our waterproofing is already fibrated and does not require the use of fabric on the entire surface, even so we recommend you use a band of fabric on critical points, the use of fabric on all the surface depends on the type of surface and the type of waterproofing).

What is the spread rate of a waterproofing presentation?
