Sadolin Extra Durable Clearcoat

Description

Sadolin Extra Durable Clearcoat is a unique formulation which offers the performance characteristics of a woodstain with minimal pigment content. Extra Durable Clearcoat works with the wood by providing a flexible barrier that protects your wood from the damaging effects of rain, moisture and sun/UV light. Behaving like a protective skin, Extra Durable Clearcoat will expand and contract with your wood to help significantly prevent blistering and flaking.

Preparation for Sadolin Extra Durable Clearcoat

General

• Timber surfaces must be suitably prepared, clean, sound and dry.
• The moisture content should not exceed 18% prior to coating.
• Resinous deposits should be removed.
• Degrease any exposed bare timber surface by wiping with a cloth dampened with methylated spirits. “Knotting agents” should not be used with Sadolin translucent woodstain systems.
• Fillers specifically designed for use with timber such as the Sadolin woodfillers should be used for making good any minor surface defects, imperfections and open joints etc. General or All Purpose fillers are not suitable.
• Only use non – ferrous screws, nails and fixings.

New Timber

• Any non preservative treated softwood timber should be treated with two liberal coats of Sadolin Wood Preserver, paying particular attention to end grains, allowing 24 hours drying time between coats and before overcoating with Sadolin Extra Durable Clearcoat.
• Where possible, the Clearcoat should be applied all round prior to fixing.

Base Stained Joinery

• Prepare all surfaces in accordance with the manufacturers instructions.
• Bare timber should be patch primed with one or more coats of Sadolin Classic in the appropriate colour to match existing base stain colour.
• Finish with 2 full coats of Sadolin Extra Durable Clearcoat allowing a minimum of 16-24 hours drying between coats.

Application

Conditions

• Do not apply if there is a risk of rain, or when air / substrate temperatures are below 8°C or above 25°C, or if the relative humidity is above 80% during application or drying periods.
• Protect from frost and rain until dry.
• Failure to meet these requirements may adversely affect the drying, visual quality and durability of the finish.

Initial Procedure

• Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced.
• Sadolin Extra Durable Clearcoat is supplied ready for use.
• Do not thin.

Applying Clearcoat

• Sadolin Extra Durable Clearcoat should be applied in a full flowing coat ensuring all surfaces and end grains are fully coated.
• For best results use a good quality, long-haired, soft bristle brush.
• Pay special attention to end grain, tops and bottoms of doors, and undersides of cills.
• Finish with 2 or 3 full coats of Sadolin Extra Durable Clearcoat (dependent on the job) allowing a minimum of 16-24 hours drying between coats.

Maintenance

• The need for maintenance is indicated by a lightening in colour, reduction in sheen as the coating erodes, and a loss of water repellence.
• All defective coatings should be completely removed.
• Any grey denatured exposed timber surfaces must be thoroughly sanded back to clean, bright timber.
• Organic growths must be removed and infected surfaces should be treated with a suitable fungicidal solution.
• Remaining sound surfaces should be cleaned using a warm water and mild detergent and rinsed thoroughly with clean water.
• Bare and previously woodstained timber should be patch primed with 1 or more coats of Sadolin Classic or Extra in the appropriate shade to match existing colour.
• On weathered / eroded surfaces apply a further coat of Sadolin Extra Durable Clearcoat overall and allow to dry.
• Finish with 1 or 2 coats of Clearcoat as required.
