Wethertex AP77 Flexible Smooth Masonry Paint is a high performance, exterior quality flexible masonry paint. Developed using advanced Optilife silicone technology for improved breathability, AP77 provides a smooth matt finish that is both self cleaning and highly weatherproof and will protect your building for up to 20 years.


Ensure all surfaces to be painted are clean, dry and free from grease and loose or flaking material that may impair adhesion. Do not apply to shiny surfaces. Scaffolding must be independently tied to allow for uninterrupted application. Any faults in the substrate, particularly those that can lead to moisture penetration, must be rectified or can affect the finish quality. Mask around the area where the material is to be applied. Masking tape must be removed before the material has dried out. Ensure all BS standards are carried out through application.


Stir the product thoroughly and do not contaminate. For the best results apply by brush, lamb’s wool roller or spray. Application tool type and quality may influence the finished appearance. Apply liberally and avoid overspreading. To avoid dampness and discolouration painting should be avoided below DPC or within 150mm of ground level. AP77 can be diluted between 10-50% depending on the suction of the substrate.

It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method. We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.

questions Terry on 2020-07-18 10:11:20

Can't find any customer reviews on how efficient wethertex AP77 is in stopping penertration of water on external masonry.


Assuming the substrate is clean, dry, sound and prepared as detailed in the Technical Data sheet, AP77 is highly weatherproof and can last upto 20 years.

questions C. Frost  on 2020-03-10 10:00:34

The building in question is concrete blocks & the top half is cladded with wood. Would masonary AP77 paint be suitable for the entire building including wood as I’d like it to be the same colour.


Wethertex AP77 Flexible Smooth Masonry Paint would only be suitable for the concrete blocks, Wethertex OT25 Wood-Flex Satin Opaque Timber Paint would then need to be used on the wood cladding. Both products can be mixed to the same colour, however if you are looking for one product to do both surfaces you could instead consider one of the Zinsser AllCoat Exterior (Water Based) range which would be fine to be applied to both surfaces after first priming the wood with Zinsser Cover Stain assuming it is currently bare.

Re Wethertex AP77 Flexible Smooth Masonry Paint is this paint suitable around windows e.g sills etc


Providing the areas around the windows are of a masonry construction then AP77 would be perfectly fine.
