Josef Koch waterproofing solution
Client – Josef Koch – Okiato
Problem:
Problem internal gutters and butynol roof parts leaking
I looked online for a simple solution and found Liquid Rubber. I called them and they were very willing and quick to help and guided me through the application of the Liquid Rubber.
Implementation and Result
Firstly, I ordered all the products I needed for the job. I used Cohe Quick Clean product, which was needed as the roof hadn’t been cleaned for about 5 years. Following this, I taped all the joins and seams with their self-adhesive seam tape. Then I applied the Liquid Rubber waterproof sealant with a brush and a roller which is purchased from their online shop. 72 hours later, I applied 2 layers of the Smoothcoat (which is available in any colour).
Liquid Rubber’s outstanding adhesive qualities and waterproofing properties make it a perfect 2-in-1 system that delivers outstanding results. It is easy to apply using a brush, roller or spray pump and can be applied to most common surfaces. To protect Liquid Rubber Waterproof Sealant from New Zealand’s harsh UV rays and increase the performance and life of the product, it is recommended that one of our Topcoats are applied over Waterproof Sealant.
Liquid Rubber is water-based, non-toxic, solvent-free and contains no VOC’s (volatile organic compounds) so is safe for both the person applying the product and the environment.
Result
I would have to give Cohe 10 out of 10 for these reasons:
- their excellent service and product
- the product was quick to arrive
- their step by step guide and online videos
- and best of all, the roof is not leaking anymore
I’m pretty proud of myself for getting this job done with Cohe’s help, of course!
