From: £65.00 £62.40

Stop varnish finishes failing. Use the trick that sailors use to get varnish finishes that last up to 20 years for low maintenance beautiful wood.

Clear Penetrating Epoxy Sealer - CPES

Smiths Clear Penetrating Epoxy Sealer™ (CPES™) is a thin epoxy that will penetrate deeply into the surface of wood. It is the ultimate primer for wood to make paint or varnish stick. CPES restores strength to rotten wood and waterproofs all wood.

Epifanes Clear High Gloss Varnish

Epifanes Clear High Gloss Varnish, known around the world, is considered the ultimate in high gloss finish. This traditional marine varnish is based on tung oil, phenolic-modified alkyd resins and maximum U.V. absorbers.

Epifanes Wood Finish Gloss Varnish

Wood Finish Gloss Varnish allows for faster building up of layers of Varnish as it does not require sanding between coats if re-coated within 72 hours.

Category: Timber

Description

Around half of the Smiths CPES sold worldwide is used as a varnish primer on new wood. It is so effective at that purpose that you can achieve 20 years before you have to sand back to bare to refinish your varnish. If you have ever had a varnish finish fail early you will know how big a claim that is, not utterly permanent – but as close as you will get.

Benefits Of CPES as Varnish Primer

Smiths CPES will:

  • Penetrate the outer fibres of the timber – leaving them waterproof yet breathable
  • Leave a hardened yet flexible surface on the timber. This is far more durable to everyday knocks than even epoxy glass sheathing, as it flexes rather than cracking when hit. Consider your freshly varnished yacht mast – and the metalwork that may ping off it on the end of a rope
  • Protect and consolidate the top fibres of the wood – leaving a firm base for your top coat
  • Physically glue the topcoat down to the wood with epoxy strength
  • Seal the edges of your plywood or the end grain of your timber like nothing else can
  • Prevent the varnish lifting from the wood banishing unsightly white spots and early refinishing

Epifanes Varnishes

The worlds best spar varnish is generally considered to be Epifanes. If you have never used it before – perhaps you should treat yourself and your wood.

We offer 2 Epifanes varnishes, High Gloss and Wood Finish. Both offer a high gloss finish. Wood Finish does not require sanding between coats, provided re-coating is done before 72 hours. Wood Finish is less clear than High Gloss Varnish. Both offer excellent UV protection. High Gloss is a required part of this kit, and you may optionally choose to purchase Wood Finish which is a popular choice to build up the initial coats of varnish.

CPES (which is sold as MultiWoodPrime in America for this purpose) will cover at approximately the following rates when used as a varnish primer applying two coats:

Maintenance

Ultraviolet (UV) Light degrades varnish. Sunlight is the strongest common source of UV light. However LED and fluorescent lighting also generates smaller amounts of UV Light.  Consequently you will have to add additional coats of varnish every year or two as appropriate. The amount and frequency of adding varnish will depend on the exposure to UV light. The UV blockers in varnishes are not UV stable by their very nature. Maintaining UV protection will keep the wood and CPES in good condition. The Smiths CPES will keep your varnish stuck to the wood.

You will have to clean the surface and provide a key with gentle sanding (400 grit or similar) prior to applying the new layers of varnish.
