omnia® is a multi-component wood coating system that offers ultimate protection against UV, weather damage and wood rot. Consisting of omnia® Wood Protect, End Grain Sealer, White Primer, and Clear and Opaque Topcoats, omnia® has been developed to multiple British Standards for exterior joinery. The omnia® exterior wood coating system also includes additional products: omnia® Knotting to help prevent extractive staining and omnia® Prime Pre-Treatment to further isolate and suppress extractives from woods, such as idigbo, sapele, western red cedar, mahogany, or other timber species that may stain the coating.

omnia® Exterior Joinery Coatings are 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 of protection against the elements as long as timber selection, preparation and design meet TWA scheme criteria and requirement standards, and the application of the wood coatings are in accordance with the appropriate Morrells product data and/or specification. This range has been extensively tested to BS 927-3 (Natural Exposure) and BS EN 927-6 (Accelerated Exposure) for use as an wooden exterior joinery finish. 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 according to the omnia® Maintenance Guide.
