Bostik Flexacryl Instant Repair Waterproof Compound for Flat Roofs, Colour: Grey, 5kg

Great product, did what it said on the tin.

You need disposable gloves and a brush very sticky even glove to glove use and throw away

Hard to judge the stars. Apply was easy, drying very long, I think a week or two to full harden. No idea why it looks so ugly haha, I was expecting super nice finish so I assume it’s a base layer and I need to put wooden plats on top of it on balcony. Water layer is fine I if applied per instruction in thick layer.

It is thick stuff and might be easier to apply with a trowel rather than a brush. The bitumen over the sill of a flat roof had cracked and split and I used this to recover it. I used plaster's scrim underneath to hold it together and give me a guide for coverage, applying a thick coat. Also repaired a couple of cracks and reinforced the area around the drainage pipe. We have had several heavy storms since I did it in the summer and there has not been even a hint of a leak in the room below. Hopefully, it will last a year or two. It is not cheap but a lot less than a new roof.

My first attempt to leave a 1 star review was rejected by Amazon. I was also advised by Amazon to leave "seller feedback" instead of a review. No idea how I'm supposed to do that when there is no ''seller feedback" option available?I am, therefore, copying and pasting another 1 star review that has already been accepted this month because this accepted review reflects EXACTLY my experience of the product.....Just received the delivery and puzzled by strong smell, started to open package and found contents had leaked out of tin into package, the mess is horrific and am now having problems getting contents off my hands, clearly this needs looking into packaging goods of this type in this way is unacceptable. Don't know how I am going to clean the mess up and get the stuff off my hands.

AAA+++

This is a great product, the delivery was fantastic, cant rate it high enough, obviously treated with absolute care, in fact I was covered in the product before I used it

Does the job well. Ensure dry and clean surface, as it says on the tin. Not cheap, but worth it.
