EverBuild 406 Stabilising Solution 5 Litre
About this deal
there is no need to use it really unless you got 20 litres of stabiliser in your garage you need to use up.
I would then proceed depending on what the edges of the cracks are like; if it is dusty/crumbly at all and no amount of stiff brushing helps this (ie - the render is a bit soft) then I think I'd run a wet Stabiliser brush well into these cracks to sort them first and then fill.
Some examples of friable surfaces are weathered cement or brickwork, and it is important to check them before applying paint.
First of all, you should make sure to do a thorough visual examination of the surface you’d like to paint, to see where stabilising solution might/might not be needed. This wall stabilising solution ensures your exterior masonry surfaces are stable for paint to adhere.
For the best results allow surfaces to cure for a minimum of 24 hours before applying the Weatherflex Smooth Masonry Paint.
But, it's a darn good product,like Stixall, but the 406 sorted the distemper ceilings here, save me a lot of work,have used gallons of it here on the walls as well.During application, make sure to use a good brush or roller, and always try to paint from top to bottom for a uniform application. When you have removed as much loose material as possible, treat the worst affected areas with a stabilising solution which will bind any reaming loose martial, presenting you with a solid surface on which to paint. For larger areas of filler I roughly smoothed over, then again used the paintbrush to texture and blend in the filler.
