Help needed - plaster / filler
Looking for help. I have about 8 holes like the images and had various
recommendations. This is what looks like plaster or browning straight onto breezeblocks. No plasterboards. Some say, use pva and the pollyfilla then sand and PVA again. Others say just use plaster. Not sure what to use for the best. https://www.homeownershub.com/img/h9 https://www.homeownershub.com/img/ha https://www.homeownershub.com/img/hb |

Use a 50:50 mix of PVA and water and paint the whole inside of the holes. Let it dry and just before applying the pollyfiller just give it a quick coat of PVA/Water again. You may want to apply two coats of filler, the first one to just below the finished surface and a second thin coat level with the finished surface. This will help minimise any sanding. You could use a finishing plaster as the "filler" -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

Don't try to get a pva coating on the surface, just 1 coat of well diluted is fine. NT |

Go with the PVA, seal with a very dilute mix and just before applying the plaster apply a second adhesive coat approx. 50:50. I would then fill with bonding coat 11mm at a time. Strike off any excess with a straight edge or Derby filling any depressions. Scarify the finished surface once set and apply finish whilst base coat has plenty of moisture. If you have to apply finish at a later date then seal the base coat surface again with dilute PVA.
One of those holes looks like the plaster on one edge is coming away from the wall, you need to enlarge the hole until you reach sound plaster. Using a hammer and chisel may cause more plaster to loosen and you end up replastering more than you wish. A gentler way of removing the plaster is to tap it to establish where it is sound and use a carbide blade in a multitool to cut an edge then use a decent scraper to prise away the plaster to your ground edge.

?. Is this a textured coating or painted woodchip ?. To me it just looks like a skim coat of plaster has just been over-painted using a emulsion and a roller giving that subtle light textured finish. -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |
