Need to render an external wall or building? The Everbuild 507 Rendagrip bonding agent will help ensure your render sticks firmly to the desired surface. You can use this all-in-one primer and sealer to form a waterproof layer on outdoor surfaces such as concrete, lightweight blocks and bricks. It contains a fine aggregate that acts as a powerful grip, as well as a polymer to allow for easy application by either brush or roller. This 10 L tub has a total coverage of 3 m².\nFor quick application, you only need to apply one coat. The formula works hard to reduce suction on porous surfaces, which means you''ll be able to save on materials. The bonding agent also stops the aggregate particles from coming loose during application. It comes in bright red, so you can easily see which areas have been treated. It''s safe to apply this weatherproof sealer and primer onto damp surfaces.\n• All-in-one primer and sealer provides waterproof coverage\n• Contains a fine aggregate to provide improved key before applying\n• For use on exterior surfaces like concrete, lightweight blockwork or brick\n• Easy application by roller or brush\n• Even spread of aggregate prevents any weak spots in key coat\n• Can be applied to damp surfaces\n• Red to indicate coverage

Brilliant for stabilising masonry, providing a good key and evening out moisture draw ensuring the render doesn’t dry too quickly.

Building Nurse Verified Purchase

Great stuff...Sticks extremely well to old bricks, render and old paint...just make sure everything is sound though before painting..100% make sure you wipe off straight away any splashes as once it's gone off you have to pick it off, which isn't easy...if going over thermo blocks, make sure you use a mesh too.. otherwise your new render could crack where the mortar joints are..

Rendagrip….yes it does

Dai C Verified Purchase

I have problems with water ingress through my garage wall took advice from a builder and he suggested before he rendered the wall I should apply Rendagrip to give added protection and ensure good adherence of the render. It was easy to apply, the colour makes it easy to see any missed spots. Two coats and allowing the drying time for him to render seems to have stopped the problem, great product highly recommend.

Good Stuff - 1st thought - a tad pricey but considering it's a 10ltr tub then perhaps not, doe's a very good job anyway....

Peter Pan and Wendy Verified Purchase

This product was used on a wall circa 1832. Prior to using the wall was being prepared for rendering with a waterproof 3:1:1 ratio mix; ie sharp sand: builders or plastering sand: cement. The builder was going to prepare the wall with drill holes approx’ 5mm deep and 2cm apart. This is a very time consuming procedure and as the wall was relatively dry, the EVERBUILD 507 RENDERGRIP was used as an alternative “key”. A 4” brush was used. A roller was tried but proved unsuitable. To get into all the “knoocks and crannies” a large exterior brush, suitable for exterior brickwork and other surfaces, was used to paint on the product. The product was easily applied and using a very heavily loaded brush only one coat was necessary. Ideally a second coat would be advisable. The product will really quickly on dry surfaces but where the base material is damp overnight curring is recommended. One coat of rendered finished with “scratch” should be left overnight before finished coat.

Easy to apply with brush or roller depending on surface being applied to. Dries quickly, able to get first scratch coat of render on same day. Excellent 'grab' qualities for applied finish. Just clean any drips or spillage with water before it dries.

Seemed to go on very well, easy to apply with a masonry brush. Too early to comment on longevity but was bought on recommendation. Even better if it was available in 5L for smaller projects (had lots left over but was able to sell it on)
