Bedec Super-Flex is a flexible and elastomeric coating for roofs and walls, quickly applied by brush, roller or spray which dries to form a high build, seamless waterproof membrane. Bedec Super-Flex economically prevents or cures all types of leaking roofs, gutters and walls. Easy to apply, Bedec Super-Flex remains flexible and elastic to allow for movement of the substrate forming a long-life protective coating for weatherproofing roofs and walls.

Recommended Uses

  • Roofing tiles
  • Slate
  • Brick
  • Concrete
  • Corrugated Iron
  • Asbestos
  • Asphalt
  • Felt
  • Copper
  • Zinc
  • Plastic
  • Timber


Surfaces should be sound, dry and free from oil, wax and grease. Remove any loose, powdery or flaking material. Surfaces, which are contaminated with lichen or moss, should be brushed clean and washed with a Fungicidal Wash and allowed to dry thoroughly before coating. Any structural repairs that may be necessary should be carried out before applying Super-flex. After preparation, one coat of the appropriate primer or sealer, as detailed below should be applied and allowed to dry:

Asbestos, Asphalt, Felt, Bitumen, Concrete, Brickwork, Rendering, Slate    Prime with a first coat of Super flex thinned with 30% clean water
Plastics Lightly abrade and apply directly
Iron and Steel Prime with an antis corrosive metal primer
Lead, Zinc, Copper, Aluminium Clean and apply direct

Cracks and Jointing Treatment

After preparation and pre-treatment, cover all joints with PVC adhesive tape, in short lengths (approx. 60cm) to avoid stretching. Apply a thin coat of Super-flex over the tape and immediate surrounding area. Stipple 15cm polyester or glass fibre scrim evenly into the wet Super-flex and allow to dry thoroughly. Apply a further thin coat of Super-flex, with a generous overlap on each side, and allow to dry. Apply at least one further full coat of Super-flex at the normal spreading rate and allow to dry. Care should be taken that the scrim membrane is properly embedded and flush to the contour of the surface. If the repair is on an area subject to standing water, the perimeter of the Super-flex system should be extended to a normally dry section.



If repair involves only small-localised cracks or fractures, apply two full coats of Super-flex over the treatment previously outlined. Where the complete roof surface is to be weatherproofed, after necessary preparation as outlined, apply two full coats of Super-flex, allowing thorough drying between each coat. In ALL cases, the Super-flex finishing coats must be brushed at right angles to each other. On roof surfaces, Super-flex finishing coats should be applied to a maximum of 2m² per litre per coat. Apply by "laying on" and do not apply like paint.

Gutters: These are normally lined with metal, asbestos or bituminous material. Failures often occur through porosity or loss of fall. To rectify leaking gutters, thoroughly clean down and apply appropriate primer or sealer, and treat cracks, fractures and joints with tape and scrim membrane as previously specified. Apply two full coats of Super-flex allowing thorough drying between coats. Do not apply to wet or damp surfaces, or where there is a likelihood of rain before Super-flex has dried.

Always apply two separate coats of Super flex and not one extra thick coat. Ponded water should be brushed away especially on freshly applied Super-flex. It is essential to build up deep depressions on flat roofs to eliminate ponding.


It is very important that Bedec Super-flex weatherproofing system should be applied to the correct film thickness. The spreading rate of 2m² per litre/per coat should not be exceeded.

questions jess on 2019-02-26 08:56:41

I need to reseal a fibreglass horsebox roof. s this the product?


We would instead suggest GacoPro Roof Coating.

questions Halle on 2019-02-04 19:06:13

I am currently building the yurt and the roof is wooden and flat but shaped like a dome, it fits together like a puzzle so each part is a triangle, would this be the best product to use?


Bedec Super-Flex can be applied to timber substrates, assuming the roof is pitched (not flat) and the wood is bare, the first coat should be thinned 30% with clean water followed by 2 undiluted coats. Due to the construction of your roof please read carefully the 'Cracks and Jointing Treatment' section on the product data sheet available to download from the product page.

questions James davis on 2019-01-30 16:19:01

Would this paint be suitable for a timber roof.

questions Reg on 2019-01-24 13:37:41

Will this go over an external concrete rendered surface that has previously been painted with black bitumen? The wall in question is south facing and gets ridiculously hot when painted black on summer. Need a light colour that will successfully adhere and cover the black bitumen. Thanks


Weathered bitumen should be first primed with a coat of Bedec Super-Flex thinned with 30% clean water, finish with 2 further undiluted coats in the chosen colour.

questions Darren on 2019-01-23 18:30:54

Would this product be good for sealing a felt flat roof?


We would instead recommend Britannia Aquashield High Build to seal a flat felt roof area.

questions Ray on 2018-10-01 09:09:13

Would this product be suitable for coating the underside of corrugated asbestos roof sheeting.


Yes, but you may find Thermoguard Asbestos Encapsulating Coating more suited.

questions IAN MERCER on 2018-09-04 11:09:38

Hi. What is best to clean brushes after applying Bedec Super Flex


Bedec Super-Flex can be cleaned off equipment whilst still wet with water.

questions John Twigg on 2018-08-19 09:43:49

Is this paint suitable for recoating an existing fibreglass covered roof? The roof was professionally installed and painted but cleaning has caused the original paint surface to appear dull. I would appreciate your advice. Thank you.


Assuming this is a flat roof, we would instead recommend GacoPro Roof Coating for this application.

questions RaymondStevenson on 2018-08-13 13:01:36

do you have a product that I can use to coat a small lead clad flat roof over my bay window Thanks


Bedec Super-Flex would be suitable for this application.

questions Aisha on 2018-08-06 11:52:22

Hi could this paint be used on see though roofing sheets & also be painted on the inside not on outside


If painting the external of polycarbonate roof lights Bedec Super-Flex would be suitable, however if you wish to paint the internal face then we would instead recommend, cleaning, lightly abrading to provide a key for adhesion and using Bedec Multi Surface Paint.

questions Byron  on 2018-04-23 16:03:50

Could it be used for a coating in a ceramic shower stall.


No, assuming it is wall surfaces we would instead recommend Rust-Oleum Tub & Tile Refinishing Kit.

questions James wheeler on 2018-03-23 18:13:06

Hi, Can I use this on a gable wall which I am due to clad in thermowood cladding. (Heat treated timber) I know w the coverage / M2 is low but this paint looks super flexible and alsbut super durable so I thought it might take a weather beating better than some other paints.


Bedec Super-Flex is primarily used on roof surfaces but as per the description can also be used on external wall surfaces with great effect.

questions Paul Churchill on 2018-03-11 21:49:15

Could this product be used to seal/waterproof a flexible pvc boat cover?


In our opinion no. We do not think it would be durable enough. The product is flexible but not enough to withstand the movement of a sheet that covers a boat. It may be OK to use as a temporary fix but we wouldn't recommend it for a long term fix.

questions Peter Foottit on 2018-01-31 09:20:48

Could this be used to cover say a timber substrate base to a small bay window pitched roof and then be painted over with an appropriate external paint?


Bedec Super-Flex can be applied to timber substrates, assuming the wood is bare, the first coat should be thinned 30% with clean water followed by 2 undiluted coats. Bedec Super-Flex is a finish in its own right so does not need overcoating.

questions Audrey on 2017-09-27 11:58:02
Question: Hi, please can you help, I have a composite slate type roof on my gazebo with a few little leeks could we use this product. Thanking you in anticipation, regards Audrey.

Bedec Super-Flex should be suitable. As long as there is a fall allowing drain off, so the water does not pool on the surface and the substrate is prepared correctly.

questions Steven Bonner on 2016-11-04 16:44:35
Question: Can this be used on artext roof or normal chalkboard ceilings above showers to waterproof?

No, something like Zinsser Perma-White Interior would be better suited to ceiling areas above showers.

questions David Adams on 2016-08-14 17:18:17
Question: Can this paint be used on a polycarbonate roof as a solar reflective coating as we have a problem with the sun's glare in a conservatory.

Yes. Ensure the surface is cleaned thoroughly and lightly sanded to provide a key. Apply directly as per instructions.

questions Jane Goldsmith on 2016-01-15 19:37:34
Question: Can this be used on fabric? I'm looking for a solar reflective coating that can be sprayed or painted onto blinds.

No, I'm afraid Bedec Super-Flex can't be used on fabric but we do offer Rust-Oleum Flexible Fabric Paint which is available in a Silver Metallic colour that would offer a degree of solar reflectivity.

questions Neil Ferguson on 2015-12-23 12:47:54

Is Bedec Super-Flex suitable for a plastic conservatory roof?


Yes. Ensure the surface is cleaned thoroughly and lightly sanded if possible. Apply directly as required.

questions gary wiseman on 2015-09-14 13:44:09

Is Bedec Super-Flex suitable for epdm roofs?


Bedec have no official testing on EPDM with the Super-Flex so they always recommend you carry out a test patch on your roof to check for adhesion and compatibility prior to use. 801 Seamless Roof Finish or GacoPro Roof Coating have been tested on EPDM and we know they perform well on this substrate.
