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 Gavin Everton on 29/10/2019

HI How much does a 2.5l cover


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.

questions RSingh on 25/05/2019

Ive got a log cabin coming, Which of the Bedec range would be best and how much would I need for a cabins size 7 meters x 4 meters? Thank you


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.

questions Rose Morgan on 03/04/2019

Can it be used over recently creosoted wood?


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. 

questions Vijay Kumar Sundaram on 28/02/2019

I have just finished an 80 Sq Metre shed (for my motorbikes and also a garden room) which has had a single coat of Ronseal Fence paint (forest green). I wonder if a second coat of Barn paint would give a long life durable finish and if so (A) how is it best applied over the fence pint and (B) how much will I need and finally which is your suitable green colour? Thank you


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.

questions Dean on 26/02/2019

What is the best spray gun or device to use for the bedec Matt black barn paint? Also what is the biggest tub it comes in? Thanks Dean


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

questions Denis on 15/10/2018

Do I need to prepare tanalised wood?


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.

questions Brian  on 14/10/2018

Can I spray the barn paint without thinning


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

questions mick edwards on 16/08/2018

Bedec Barn Paint or Zinsser Allcoat Exterior Water Based Paint for new wooden garage doors Thanks


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.

questions Dabe Cuff on 07/04/2018

Can i use barn paint on mew cedar; I am told cedar has a high level of natural oil in it.


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. 

questions Barbara Macleod on 03/11/2017
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

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.

questions Mrs Willoughby on 25/11/2016
Question: Can you tell me how often the barn paint has to be reapplied?

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.

questions mrs j hewings on 09/05/2016
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

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.

questions john rush on 10/09/2015

Can I use Bedec Barn Paint in a spray gun?


Yes, use HVLP or Airless spray for best results.

questions Scott Ranger on 22/06/2015
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.

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.

questions James Chester on 18/05/2015
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?

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.

questions Andrew Shepherd on 15/05/2015

How many coats of Bedec barn paint are required to cover an already treated fence?


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.

questions Janet budd on 14/05/2015

Is your Bedec barn paint suitable for painting a resin garage door? If not, what would you recommend?


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.
