Sadolin Classic soaks into bare timber to provide a base coat to be subsequently treated with a finishing coat like Sadolin Extra. It provides tough weather protection and provides excellent durability. It is an ideal system for new or bare timber joinery. Sadolin Classic should not be used alone as a finish for hardwood timbers. Phillips Joinery Ltd will apply one coat of Sadolin Classic to your product, as standard.
Preparation for Sadolin Extra
Denib using a fine grade nylon abrasive pad or a fine grade wet or dry silicon carbide abrasive paper, in the direction of the grain. Do not break through the surface coating. Remove all dust.
Sadolin Extra – Coating System
Apply two coats of Sadolin Extra onto a base stain of Sadolin Classic for optimum performance. Maintenance will usually only require one additional coat, unless the surfaces are excessively weathered.
Touch dry: 5-7 hours
Recoatable: 12-18 hours
Drying times are dependent upon absorption and drying conditions. At low temperatures and/or conditions of high relative humidity, drying times may be extended.
Ensure product is thoroughly stirred before and during application, otherwise sheen and colour variations may be experienced. Extra is supplied ready for use. Do not thin. For best results use a good quality, long-haired soft bristle brush. Two coats of Extra should be applied, allowing a minimum of 18 hours drying time between coats. The second coat should be applied as soon as possible after the first coat, but no sooner than 18 hours. The product should be applied in a full flowing coat, laying off in the direction of the grain, using a minimum number of brush strokes necessary to produce an acceptable finish. Avoid over brushing, as this will reduce the protection afforded.
Do not apply if there is a risk of rain, or when air/substrate temperatures are below 5oC or above 30oC during application or drying periods. Protect from frost or rain until dry. Failure to meet these requirements may adversely affect the drying and visual quality and durability of the finish.
Maintenance of Coatings
The period between maintenance applications will vary and is dependent upon the degree of exposure, elevation, design of the component and original application. A lightening in colour and reduction in sheen as the coating erodes, and loss of water repellency indicate the need for maintenance.
Any loose, flaking coating should be removed by use of a scraper and abrasive paper. Any other loose material should be removed using a stiff (non-metallic) bristle brush. Any mould and algal growth must be removed using a suitable fungicide/algicide. Wash surfaces with water and a mild detergent to achieve a clean surface. Rinse thoroughly and allow to completely dry. This should be carried out immediately prior to application of coatings.
Coatings in poor condition should be removed completely. If excessive weathering has occurred giving exposed timber a grey appearance, the surface must be thoroughly sanded back to clean, bright timber and then treated as new timber, with Sadolin Classic being applied first.
