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® Clear System

The omnia® Clear system mainly consists of omnia® Wood Protect, End Grain Sealer and Clear exterior topcoats, but can also include 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.

1. omnia® Wood Protect - waterborne timber protector offering protection against rot and fungal attack.
2. omnia® End Grain Sealer - waterborne sealer used to reduce moisture absorption and to close the porosity of timber end grain.
3. omnia® Clear Topcoat - high performance, microporous exterior topcoat with UV diffusers.

omnia® offers many years of protection against the elements as long as timber selection, preparation and design meet TWA…

A pale shellac solution formulated to seal knots found in timber. Knotting solution will help prevent extractive staining but will not completely stop the resinous excretion exuding from the knot after the timber has been painted.

Brush directly over knots only.

Always check the suitability of the timber for exterior joinery application prior to commencement of the project. Please consult the Usage tab for more information on the omnia® system.

• Pack size: 1L, 5L & 25L
• Coats: 1 x coat over knot only

A high performance waterborne timber protector ideally suited to dip, flow, spray and brush application. Offering excellent coverage and durability, complete with specific additives which protect the structure of the wood and actively control discolouration.

Previously known as omnia® Preserve.

omnia® Protect is formulated to provide surface protection against rot and fungal attack. omnia® Protect comes in clear and is also available in 9 standard wood stain colours: antique pine, light oak, teak, mahogany, dark mahogany, rosewood, walnut, dark oak and jacobean.

Use prior to end grain sealing with omnia® End Grain Sealer. After Preserve, apply omnia® Clear. Refer to the Usage tab for more information on omnia® Protect's use in the clear finishing system. Always check the suitability of the timber for exterior joinery application prior to commencement of the project. Please consult the Usage tab for more information on the omnia® system.

Usage

Ensure that the substrate is clean, dry and free from contaminants. 

Wipe all surfaces with a sharp solvent such as Morrells Cellulose Thinner (2007/000) prior to coating application. Turn the wiper so that the contamination is removed rather than dispersed. Allow the solvent to flash off for 30 minutes and apply the first surface coating within two hours of cleaning. Observe Health and…

A waterborne sealer used to reduce moisture absorption and to close the porosity of timber end grain. This product must be used as part of the recommended omnia® system. omnia® End Grain Sealer is a high viscosity product designed for brush application and formulated to achieve good penetration, flexibility and moisture repellence.

Use in both the clear and opaque omnia® finishing systems. More information on the finishing systems can be found in the Usage tab.

Always check the suitability of the timber for exterior joinery application prior to commencement of the project. Please consult the Usage tab for more information on the omnia® system.

Exterior Joinery Maintenance Guide

Whilst timber coating systems are guaranteed to last many years in an exterior environment, certain considerations must be made to ensure joinery remains in a sound state. The natural beauty of timber as a material for Exterior Joinery means that, if maintenance is carried out regularly, it will retain its visual appeal for a lifetime.

It is important to remember that regular, minimal maintenance will make recoating / re-decorating joinery a far easier job and as such, Morrells have compiled an easy to follow maintenance plan. 

Points to note

Mould and Algae

Whilst mould and algae pose little initial threat to the coating other than the aesthetic appearance, prolonged contact can have a detrimental effect on the coatings surface and lead to water absorption issues over time.

Whilst soapy water may work for early mould attacks, a wipe with a solution of one part bleach to five parts water should be enough to remove most stains. If the discolouration persists then use of a nylon bristled brush (Not metallic) can be used to remove the more stubborn stains.

Damage

Areas where the coating has been damaged or more severely eroded to the point where bare timber is…
