ASMACOAT WP 5900 shall be applied as per the following general method of application.
A. Substrate preparation:
The performance and ultimately durability of the coating largely depends on the condition of the substrate. Therefore, conditioning and preparation of the substrate is of utmost importance. .
Concrete surface: The surfaces shall be thoroughly cleaned to remove all dust particles and laitance.
Surface defects like potholes and pinholes on building facades on the concrete shall be repaired with an appropriate polymer modified repair mortar.
Metal surface: The surface should be cleaned from all rust scales.
This can be achieved by wire brushing or grit blasting. For higher strength and flexibility, insert a non-woven geotextile membrane whilst the first coat is still wet on all corner joints, fillets, and pipe penetration joints.
Allow the coating to fully cure for 72 hours to achieve its full properties.
B. Mixing:
When a container is opened, the contents may have settled or separated over time, especially if the product has been sitting on a shelf or in storage for a while.
