I've not seen one of these before, looks like it could come in handy.
I have had a closer look at the render surface now that all the patches have been exposed and there is no visible sign of a scratch coat key but it isn't dusty so will just pva and skim . I wont be rushing to get the steamer out too quickly in future!Possibly dust on wall before skim applied, possibly no scratch to hold it, possibly dried too fast,
get rid of loose plaster, pva and bond in the patches, give it all a weak pva then a second when first dries, ready for skimming then,
If the paper wont come off just pva and skim over it. Or is it just wood chip you can do that on.?:RpS_blink:
I found one the other day but it was as flat as a pancake, I suppose I could use it as sandpaperA roadside hedgehog will cover a larger idea surely?
