Approximately 13-15m² per litre/per coat when applied by brush or roller depending on the texture and porosity of the substrate. Applying by airless spray would reduce the coverage to approximately 6-8m² per litre/per coat.

We would normally recommend Wethertex OT25 Wood-Flex Satin Opaque Timber Paint for this type of application. Assuming you have around 40m² of area to paint, 1 x 10lt of this product would be sufficient to apply the recommended 2 coats.

Creosoted timber must be left a minimum of 3 months to weather before applying Bedec Barn Paint. After 3 months a test patch would still be recommended to confirm adhesion. 

Assuming the Ronseal product is suitable to be over painted with Bedec Barn Paint (you would have to carry out a test to check) then at least 2 coats of Bedec Barn Paint should be applied. Based on 80m² you would require approximately 6 litres per coat.

The manufacturer recommends HVLP or Airless Spray for best results. The largest pack size the product comes in is 20 litres.

Bedec recommend waiting 6 months before painting tanalised wood to allow it to weather. After this time Bedec Barn Paint can be applied, however they advise to dilute the first coat with 30% water. This soaks into the wood and acts as a primer, then go on with another 2 undiluted coats to finish.

Yes if applying by airless spray and the substrate permits it.

We would recommend for bare exterior timber first priming with Zinsser Cover Stain followed by 2 - 3 coats of Zinsser AllCoat Exterior (Water Based) in the colour and finish of your choice.

Yes, there would be high levels of tanning's present. There would be a fair chance that staining will occur so we would recommend a stain blocking primer to be applied first such as Bedec Stain Block, then Bedec Barn Paint could be applied. 

Bedec Barn Paint isn't suitable for use over oils, it is suitable for use over existing paints after preparation but still isn't recommended for furniture surfaces such as table tops or seat tops where the surface will receive regular wear and tear.

There is no definitive answer for this but we would expect 3-5 years to first maintenance of a correctly prepared and applied system.

This is assuming, not south facing, no extreme weather conditions, etc.

Yes you can, on existing painted surfaces, remove all loose and flaking paint and thoroughly rub down with abrasive paper. Any new finished wood needs to be abraded. On untreated, weathered wood, new wood, cement, render etc. or any porous substrate the first coat should be thinned with 20-30% clean water. Some surfaces are liable to have water solubles or wood treatments which can cause staining and loss of adhesion especially with white and lighter colours. Substrates to be careful of are some plywoods, red cedar wood, very resinous timber or damp walls. Test areas liable to staining and seal with Bedec Stain Block. Once prepared apply 2 coats of Bedec Barn Paint, the life expectancy to first maintenance would be approximately 3-5 years.

Yes, use HVLP or Airless spray for best results.

Bedec Barn Paint would be ideal for this project. Ensure all surfaces to be painted are free from oil, grease, dirt, dust and loose particles and sand to provide a key. On Cedar woods we recommend a first coat of Bedec Stain Block is applied to prevent staining and loss of adhesion. Once applied and dry apply 2 subsequent coats of Bedec Barn Paint in the desired finish and colour.

Jotun Demidekk Decking and Garden Stain is a special translucent woodstain for treating pressure-treated wood used in decking, fencing and garden furniture that gives up to 3 years protection in just 1 coat.

2 coats are all that should be required. On existing painted surfaces, remove all loose and flaking paint and thoroughly rub down with abrasive paper. Ensure all surfaces are free from oil, grease, dirt, dust and loose particles before painting.

No, Bedec Multi Surface Paint would be better for your garage door as it is excellent internally and externally on a wide range of surfaces including plastic. Although Bedec Barn Paint can be applied on other surfaces it is primarily intended for use on exterior timber.
