omnia® Exterior Joinery Coatings

omnia® is a multi-component system that offers ultimate protection against UV, weather damage and wood rot. Consisting of omnia® Wood Preservative, End Grain Sealer, White Primer, and Clear and Opaque Topcoats, omnia® has been developed to multiple British Standards for Exterior Joinery. The omnia® system also includes additional products: omnia® Knotting solution to help prevent extractive staining and omnia® Prime Pre-Treatment to further isolate and suppress extractives from red-brown hardwoods, such as sapele.

omnia® is suitable for multiple wood types, as well as Accoya® acetylated wood. Guidelines for the use of omnia® with Accoya® can be found in the omnia® Exterior Joinery Guide for Accoya®.

omnia® offers many years protection against the elements as long as timber selection, preparation and design meet TWA scheme criteria and requirement standards, and the application of the coatings are in accordance with the appropriate Morrells product data and/or specification. Though omnia® offers UV protection, water repellency and weather protection, very exposed or coastal locations can reduce the longevity of all exterior coatings. For this reason annual inspections and maintenance must be carried out with the omnia maintain range of products.
