Honda is a project that we have been working on for 2 years since 2008. We have done waterproofing work for a number of roofs including steel metal sheet roofing and concrete roofing. For the metal sheet roofing we used a special silicon from Japan and our own brand insulation paint. For the concrete roofing we used an acrylic roof coating that keeps out all the rain. Again as a top coat on some areas we used insulation paint.
