How To Fix Failed Plasterboard Joint Step By Step

[@christopherlocke6115]

I had cracks like this on my livingroom ceiling , I did this last year & you would never know it was there and no signs of it coming back 👍👍👍I've learnt so much from this channel, big thanks lads much appreciated

[@PaintingandDecorating]

Thanks from both of us.. Nice to know

[@bryandennett2492]

In all my many years in the trade, I had never thought of adding some colour to the filler when filling. I’ve always spot primed afterwards. Never to old to learn a new trick. Thanks for the tip 👍🏻

[@PaintingandDecorating]

Thank you...

[@daveh1081]

You gotta love the snipers! Thanks to you guys, I've added this technique to my armoury with great success! Many thanks and have a great christmas!!

[@PaintingandDecorating]

Thank you.... Merry Christmas

[@michaelsalt4565]

First time I've seen this technique used, definitely going to give it try. Using expanding foam is a genius idea.

[@PaintingandDecorating]

Thanks... works really well on difficult cracks...

[@fluxant]

Pva and expanding foam in the same video , must be Christmas

[@jabberwock95]

After carefully watching all these videos, I'm building my next house out of Soudal Expanding Foam.

[@rickyjohnson3650]

Fantastic job.

[@PaintingandDecorating]

Thanks

[@hamiltonlowry1018]

Nice job once again I have done it your way with great results Thanks to you once again Happy Christmas to you and your family

[@PaintingandDecorating]

Thank you... and you Happy Christmas 🎄

[@squeakmillward]

love the idea of colouring up the hard stop

[@colliedogjoy]

Lost count of the number of jobs I've done like this.The cracks never come back. Many thanks. I use the tubs of ready mixed filler... they take a drop of paint well and no flashing.

[@PaintingandDecorating]

Nice one.. makes such a difference always have a can on the job.. thanks

[@richardmcdougall233]

It maybe depends on just what brand type of ready mix filler you use. Some are better than others

[@colliedogjoy]

The ones I mix to a hard stop are both Polyfiller, the All Purpose and the Quick Drying. Both heavy tubs, not lightweight acrylic fillers.

[@michaelmercury1256]

Great work and well done as per usual. Please I have a 2mm or so crack line open along one side of a 4 metre length ceiling/wall intersection. Do you recommend using the expanding foam or adhesive foam of your favourite brand and what spacing do you suggest for the holes? Sorry last question, should I try to push back or support ceiling board, whilst the foam is setting, or not bother about a 2 mm sag? Many thanks...

[@PaintingandDecorating]

You could try and push back but 2mm probably not noticeable. We only use expanding gap filling foam which acts like a adhesive anyway. Watch this video kzbin.info/www/bejne/apmZqHeLZr2DqpI

[@waitinginthepipeline]

Excellent video.One quick question,do you need to let the pva solution dry first?

[@PaintingandDecorating]

Thank you No not fully...

[@ccn78]

I have watched your previous videos and used this technique. It’s worked great with only one or two cracks coming back. Question; what do you do if there is no cavity behind the crack for the foam to mushroom out onto the back of the board? I think I have a joist/ beam behind one I am trying to fix at the moment. Still use the foam or try mechanical fixing? Any guidance much appreciated and thank you for all the great videos!

[@PaintingandDecorating]

Thank you... screws can help and small amount of foam.

[@richardmcdougall233]

I think you can get " no expand " foam.

[@teckelteckels2730]

Interesting. What's the purpose of the holes and foam? To stop the crack coming back?

[@PaintingandDecorating]

Thanks.... it all acts like a flexible stitch.

[@MarcGray1990]

Literally exactly what I’ve been doing today in my own bedroom. Few ceiling cracks but the ceiling has been over boarded so I only poked holes through the first plasterboard and foamed them in. Effectively gluing one plasterboard to the original underneath. Done it in a few other rooms of my house and it holds well. I did however use guardz rather than pva… purely because I had a tin next to me and the pva was in the garage haha! Seems to set the foam off in the same time and seal the dust down too. Using toupret tx110 at the minute which seems good gear to go off quick! Thanks for the upload ! Marc

[@PaintingandDecorating]

Your welcome.

[@daveh1081]

@@ryansmyth3877 Okay mate.........fair enough, but care to enlighten the rest of us instead of just sniping. Where appropriate, I use this method with great success......and it's all down to these guys. I also use other methods, ie mechanical fixings in other situations..........but genuine request, share your knowledge.

[@keesdejong4727]

Hi, what is the logic / function of the holes and the foam, as opposed to just using pva and filler? And is it a rule to have a hole at the beginning and end of the crack? (As you'd do with tears along the grain in wood, because it creates a stop to the wood 'tearing' further...) I would imagine that you'd need to put foam along the whole length of the crack...

[@PaintingandDecorating]

Acts like a stitch.. thanks

[@philm6629]

What filler did you use? Would "One Strike" do the job? Can you mix emulsion with One Strike? Thanks

[@PaintingandDecorating]

If its a powder filler then yes.. ready mixedis more difficult.. thanks

[@Brandon-ko3rf]

Then fibreglass resin? No man, I’ve watched many repair videos & this one is def a 1st time seen

[@jsj381]

Brandon scrim tape can work in certain situations but not this one as its on the celing. Just follow these boys they know what and how to get it done right the first time trust me P&D 12 years going strong.

[@TapelessDrywallFinishing]

👍👍

[@richjtg]

Please can I ask how do you stop your can of expanding foam going off between jobs?

[@PaintingandDecorating]

Watch this video it may help to explain kzbin.info/www/bejne/ipCQmmealqxgmJY

[@richjtg]

@@PaintingandDecorating Amazing - thank you!

[@angrygromit93]

not sure I understand the purpose of the expanding foam?

[@shayanchaudhary8613]

I beleive it's for filling in any large gaps and lettings the "loose" plaster stick to the material behind it as it can act like glue stopping any further cracks from forming in the same area.

[@nrosko]

followed this trick without mixing paint but filler cracked where it met the ceiling.

[@PaintingandDecorating]

Practice makes perfect..

[@nrosko]

@@PaintingandDecorating admittedly it was my first attempt, probably didn't widen the crack enough or pva mixture wrong. one of a few mistakes i made on the ceiling including plaster falling off when rolling paint where somebody had filled over nails, lint falling off roller.

[@squeakmillward]

get the shave hook down it

[@Brandon-ko3rf]

Mate, you’re meant to use tape over plaster then plaster over, not expanding spray filler. 🧐

[@NiktheEnglishGreekCypriot]

You do realise that cracks that are taped over can still and often do crack because the actual issues of movement are still there? Ie cracks after brand new plastering appearing on joins and corners etc. the foam stops movement, which causes cracks, very simple

[@lifter98]

Nah!

[@NiktheEnglishGreekCypriot]

@@lifter98 to who, I’m very intrigued especially at your answer with no factual response whatsoever

[@ryandineen3344]

Tape fails.. This works.. Could do both to be certain
