Beatrice,I beg to differ because Ive been in the construction industry for 22 years. In that time Ive seen a lot of DIY shoddy work that doesnt stand up tp warranty performance.The vast majority of roofs installed are not installed correctly. The vast majority of paint jobs are nothing more than a whitewash that last 2 maybe as long as 5 years. Ive seen vinyl siding warped wrinkled and falling off and in most cases it was installed by a DIY or a helper turned contractor.
How you going to apply 14mils and get a 8mil dryfilm thickness consistently,prep the job to protect from adhesion failure as a result of vapor pressure. Please work on your own home please and not hand out advice please
