Sadolin PV67 Heavy Duty Varnish

Sadolin PV67 Heavy Duty Varnish is one of the few protective coatings we can confidently recommend as a wooden bar top lacquer. Other areas of use include dance floors, community halls, sports hall floors, restaurants, shops and office flooring.

Please Note: This product is for interior surfaces only and is not suitable for exterior projects. It is also unsuitable for use on laminate flooring or other laminated surfaces.

Where a coloured lacquer finish is required, Sadolin PV67 may be applied over 1 coat of Sadolin Classic Wood Protection or a similar low-build wood stain once the coloured base stain has fully dried.

• Looking for a durable Polyurethane varnish more suitable for domestic environments? Consider Sadolin Polyurethane Floor Varnish, a single-part, water-based floor varnish.

Bar tops and other wooden surfaces must be clean, dry and free from all surface dirt, debris and other contaminates prior to coating with Sadolin PV67 Heavy Duty Varnish. Timber must be intact and in good condition with a moisture content of no more than 14% prior to coating.

New and Bare Timber

• Compatible fillers such as Sadolin Wood Filler or Sadolin Stainable Wood Filler should be used for making good any minor surface defects, imperfections and open joints etc
• General or 'All Purpose' fillers may not be suitable
• Knotting agents should not be used with Sadolin varnish systems
• Only use non-ferrous screws, nails and fixings
• Resinous deposits should be removed from the wood with a scraper
• Remove any remaining residues and degrease any exposed bare timber surface by wiping with a clean, lint-free cloth, moistened with methylated spirits
• Allow methylated spirit to fully dry before overcoating

Previously Coated Wood

• Sadolin PV67 Heavy Duty Varnish should not be applied to conventional single pack varnishes, either solvent-based or waterborne
• If in any doubt about the nature of an existing finish, it must be completely stripped back to bare wood and treated as 'New Timber'

Always do a test area before starting any project to test product suitability and final finish. Follow the manufacturer's instructions on the tin at all times. PV67 Heavy Duty Varnish is ready to use in its combined form and does not require thinning. It is not recommended to increase the speed of drying by using additional hardener. Protect from water until dry.

Warm and dry conditions assist with proper drying / curing. Excessive humidity or low temperature will affect the chemical reaction in the finish, causing incomplete drying / curing. The formaldehyde release period can also be negatively affected. To minimise such problems, application of PV67 Heavy Duty Varnish is recommended between 18 and 25° and not above 65% relative humidity. If there is any doubt regarding the level of humidity present, a dehumidifier should be used prior to, during and immediately after application.

Good air flow and ventilation are essential at ground level during and after application. Where air circulation is poor, the use of an electric fan is recommended to assist air movement in the room. Do not direct drafts at the surface. The moisture content of the timber should be allowed to stabilise to the conditions within the room, and should not exceed 14%.

1. Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced
2. Sadolin PV67 Heavy Duty Varnish is mixed in the ratio of 10 parts varnish to 1 part hardener, by volume
3. The varnish / hardener mixture must be thoroughly shaken immediately prior to use
4. As the hardener contains acid, mixing should only take place in suitable vessels made of plastic, glass or an undamaged enamel vessel

Please Note: Once the 2 components of the varnish have been mixed, the product can be stored in a closed container below 20° and remains usable for up to 3-4 hours. However, we strongly recommend only mixing sufficient material for individual coats at any one time.

1. Apply Sadolin PV67 in full flowing coats, ensuring wooden bar tops and other surfaces are fully coated with the lacquer
2. For best results, use a soft, natural bristle brush, lambs wool applicator or quality woven short to medium pile roller
3. Finish with 3 full coats of Sadolin varnish allowing a minimum of 3-4 hours drying between coats
4. Avoid over-brushing as this will cause brush marks and result in a poor quality finish and also reduce the level of protection afforded
5. Carefully denib the fist coat using a fine grade nylon abrasive pad or a fine grade (P240 or finer) wet or dry silicone carbide abrasive paper in the direction of the grain before over-coating
6. Do not break through the surface coating and remove all sanding dust
7. All subsequent coatings should be applied as soon as possible after the previous coat has fully cured

Cleaning Equipment

Clean application tools prior to use to ensure that any fibre shed is minimised. Wash applicators and allow to fully dry. Masking tape can also be used to remove loose fibres.

Some Points of Note:

• Do not allow heavy traffic for at least eight hours after application
• Do not install furniture until 24 hours after application
• Do not install rugs until one week after application
• Newly applied surfaces should be allowed one week complete curing time before any cleaning is undertaken
• Some timbers, in particular pine with a high proportion of heartwood, may darken on application

Regular Cleaning

Floors and surfaces coated with Sadolin PV67 must not be cleaned with wax polishes, strong detergents or caustic soda. Cleaning with a pH-balanced wooden floor cleaner and a damp (not wet) microfibre cloth / mop is all that is required. Surfaces can then be buffed with a dry cloth or mop to restore the sheen if required.

Maintenance

If maintenance becomes necessary, surfaces should be lightly sanded with a fine grade abrasive paper. Remove all dust completely and apply one coat of PV67 Varnish (two component).

Repair

• Small areas that have become worn can be maintained by 'feathering' a maintenance coat into the surrounding varnish after using a fine grade abrasive paper to prepare the surface
• Coatings in a poor condition should be removed completely
• Emulsion dressings must be removed before maintaining with Sadolin PV67 Varnish
• Newly applied surfaces should be allowed one week complete curing time before any cleaning is undertaken

Sadolin PV67 can only be used on wooden surfaces as the varnish needs to bind to the wood fibres.

As a solvent-based varnish, this has been known to enhance the natural tones of the timber significantly when used on a species like pine. You may wish to swap to an alternative water-based varnish instead. Why not give our Woodcare Experts a call on 01303 213838 to discuss your options.
