Timbacryl®

Use Dulux Timbacryl over dressed and rough sawn timbers, pergolas, decking, fences, fascia boards, timber furniture, bricks, masonry, fibre cement sheeting, Zincalume® & galvanised iron.

Different surface conditions and substrates require different preparation to get the best results.

Before you start check the weather forecast.
• Air and surface temperatures must be above 10°C during application and drying time.
• Do not paint on excessively cold or humid days or when rain is forecasted. On cold days, good air movement will aid drying time, and stop painting with enough time to ensure it dries before evening.
• Exposure to rain or overnight dew whilst drying may result in the coating being damaged or removed.
• If painting during the hottest time of the day, paint on the shady side of the house. 


Previously painted surfaces
Pre-primed timber and previously painted surfaces: 

• Pre-primed timer: Follow the timber manufactures recommendations
• Occasionally an apparently sound old paint will lose adhesion when recoated, particularly if the new paint is darker in colour. 
• To avoid this, check the adhesion of the old paint by cutting an 'X' through a clean area of the film with a sharp knife, press cellulose tape firmly across the cut and rip it off. 
• If the old paint comes off with the tape it should be removed before repainting. 
• Scrape off all loose and flaking paint.
• Fill any cracks or holes with a suitable filler. Dulux recommends Selleys products.
• Sand all surfaces to a flat finish and remove greyed timber. 
• Dust off. 
• Spot prime any bare areas with Dulux Timbacryl or the recommended primer for the substrate being painted (See Unpainted surfaces)
