Exterior Building Paint
Bedec Barn Paint is a long lasting finish ideal for use on exterior wood, plastic, concrete, weathered galvanised steel, brick and cladding.
Bedec Barn Paint is ideally suited to the protection of exterior buildings such as barns, stables, outbuildings, sheds, silos, windmills, and factory units (corrugated and metal box cladding). It is highly recommended to coat, fencing, gates, farm equipment, tanks, drainpipes, doors, windows and many other areas around gardens, farms and factories. It can be applied to previously painted surfaces, even those coated with weathered bitumen, tar varnish or creosote.
This acrylic system is a tough durable microporous protective coating with excellent colour retention. It will flex with the substrate exhibiting reduced flaking and blistering. Two or three coats can be applied quickly within one day, especially during the summer months. The advantage over conventional systems is that the coats applied are all Barn Paint, therefore no stress is built up within the coating layers. No need to etch or pre-prime weathered galvanised steel but bare steel or rusty surfaces must be primed with with Bedec Metal Primer.
Black Barn Paint and Assorted Semi-Gloss Colours
COLOURS - Bedec Barn Paint is available in Matt, Satin and Semi-Gloss finishes in Black and White ONLY. All other colours are only available in the Semi-Gloss finish.

Questions
![]() | Question: Do I need to prepare tanalised wood? |
Answer: 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. | |
![]() | Question: Can I spray the barn paint without thinning |
Answer: Yes if applying by airless spray and the substrate permits it. | |
![]() | Question: Bedec Barn Paint or Zinsser Allcoat Exterior Water Based Paint for new wooden garage doors Thanks |
Answer: 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. | |
![]() | Question: Can i use barn paint on mew cedar; I am told cedar has a high level of natural oil in it. |
Answer: 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. | |
![]() | Question: I have Garden furniture, bare wood but regularly oiled. Can it now be painted, eg with barn paint? Second question: can I use Barn paint on garden furniture which has been previously painted with oil based paint? Thanks |
Answer: 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. | |
![]() | Question: Can you tell me how often the barn paint has to be reapplied? |
Answer: 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. | |
![]() | Question: could you please tell me if i can use bedec barn paint on my wooden park home ,as previous ronseal wood stain peal and crack ,and if i can could you tell me how often do i have to re-paint thankyou |
Answer: 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. | |
![]() | Question: Can I use Bedec Barn Paint in a spray gun? |
Answer: Yes, use HVLP or Airless spray for best results. | |
![]() | Question: I have just bought a cedar greenhouse which is about 15 years old and has had a treatment of red cedar preservative applied to it some years ago. Please can you tell me if the barn paint is suitable to use on it. What preparation do I need to do to the wood first ? Many thanks, Scott. |
Answer: 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. | |
![]() | Question: I have a static caravan which has a large veranda and decking. This has been treated previously with a wood stain which is now flaking off in places but in other places is sound. I would like to re-paint this, changing the colour from dark brown to dark green. As there is a large area I would like to do this with as few coats as possible - one coat would be nice. Can you recommend a suitable paint which gives good obliteration of previous coatings, quick and easy to use and is relatively cheap? |
Answer: 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. | |
![]() | Question: How many coats of Bedec barn paint are required to cover an already treated fence? |
Answer: 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. | |
![]() | Question: Is your Bedec barn paint suitable for painting a resin garage door? If not, what would you recommend? |
Answer: 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. | |
