omnia® Prime Pre-Treatment

A stain-inhibiting waterborne clear isolator and extractive suppressant for the treatment of sapele, iroko, teak and other red-brown hardwoods prior to finishing where resin and extractive exudation may interfere with the finishing of the timber when using a pigmented topcoat.

Ideally suited to spray application, this product is recommended as a pre-treatment primer before application of omnia® Prime, and should be used over the recommended wood preservative/wood treatment. Please consult the Usage tab for more information on finishing.

Tested to BS 927-3 (Natural Exposure) and BS EN 927-6 (Accelerated Exposure) when used as a pre-treatment under omnia® Prime.

Usage

omnia® has been designed as a full finishing system, from surface preparation to topcoat. As omnia® is available in clear and opaque topcoat systems for multiple varieties of wood, please consult our Exterior Joinery Guide for Exterior Finishing and the system guidelines below.   Choose your system below:

Ensure that the substrate is clean and dry. 

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 Safety matters. 

Clear Finishes:

  1. Apply a coat of omnia® Preserve in its clear form or in the appropriate colour. Ideally applied by dipping or flow coating but if brushed or sprayed, ensure that the surface is fully wetted so that the timber absorbs the product. The system is designed such that any stain colour can be obtained by the application of tinted omnia® Preserve. However, for special requirements, the topcoat can also be tinted by our Fastmatch® colour-matching facility.
  2. Treat/seal all end grain with brush applied omnia® End Grain Sealer (8ES/000) and allow to fully dry before denibbing the End Grain Sealer only.
  3. DO NOT denib omnia® Preserve before applying subsequent finishes.
  4. Apply two coats of omnia® Clear to a wet film thickness of 150 -175μm per coat. Lightly denib prior to the application of the final coat, using a synthetic sanding pad (Scotchbrite or similar).

 

Product Coating Recommendations:

Ensure that the substrate is clean and dry.

Wipe all surfaces with a sharp solvent such as Morrells Cellulose Thinner (product code 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 Safety matters. 

 Solid (Opaque) Colours:

  1. Apply a coat of omnia Prime Pre-Treatment (8PT/000), a stain-inhibiting clear isolator when coating sapele or other red-brown hardwoods. Ensure the surface is fully wetted so that the timber absorbs the product.
  2. Treat/seal all end grain with brush applied omnia End Grain Sealer (8ES/000); allow to fully dry before de-nibbing only the end grain sealer.
  3. Apply one coat of omnia Prime which is a stain inhibiting white Primer to a wet film thickness of 150μm.
  4. Apply two coats of omnia Colour (Opaque Topcoat) to a wet film thickness of 150-175μm per coat.

Lightly denib prior to the application of the final coat, using a synthetic sanding pad (Scotchbrite or similar).
