(p.s. if you lot desire to remove your lath and plaster ceiling, you can head over to the "How to Take Down Lath and Plaster Ceilings" folio instead). Well-nigh people agree that traditional lath and plaster ceilings (and walls), really add together charm and enhance the feeling of living in a period house. Eventually though, old board & plaster is prone to nifty, sagging or even falling down. The skilful news is that it'southward often possible to repair board & plaster ceilings (and walls) and brand them concluding a skilful while longer (if you similar the look and feel). For those that have gone too far and need replacing with something else, nosotros'll look at the unlike options open up to you. What you cull depends on the expect or experience you're aiming for, your budget and your 'tolerance' of erm…..how can I put information technology; 'rustic' surfaces! It'southward also a universal truth that the 'flatter' and most 'long lived' repairs cost more to carry out and the older your lath and plaster, the more than work information technology's likely to need.

OK, enough blurb, lets get started……

Hither are the Summit Ten Xi Means to Repair Lath and Plaster Ceilings and Walls

Pretty much in society of cost/complexity/longevity…….

Re-decorate the Plasterwork As Information technology Is

The most minimum work, arguably not even a repair but basic maintenance. Vacuum to remove dust, (wash down, if required) and and so re-decorate, preferably with a lime based pigment (if the ceiling is completely original) or nigh likely with suitable water based paint. Not a good repair if the plasterwork has gone beyond the dandy phase, i.e. sagging badly, so this depends on the plasterworks condition.
- Cost: Very economical and quick.
- Pros: Period charm in abundance. Ideal for very old cottages that don't accept a straight edge or surface in them. Shows imperfections.
- Cons: Possibly very short term solution for damaged plasterwork and fifty-fifty potentially dangerous if really bad! Not a 'flat' finish. Shows imperfections!

Repairing Cracks in Lath and Plaster (Ceilings and Walls)

If the plasterwork has croaky or crazed simply is however firmly adhered to the laths then you could just fill the cracks and blemishes and redecorate. Offset scrape out all cracks and vacuum out loose textile. Prime the cracks with a suitable primer like unibond and then fill cracks and small blemishes with decorators' filler using a suitably sized scraper or drywall spreader. Push the filler in at 90 degrees to the scissure and then press to flatten out and scrape off excess by running the scraper along the scissure. Gently sand the filler flat if necessary (shouldn't need much) and vacuum all dust abroad. Fine cracks could be filled with a flexible decorators caulk and smoothed over with a damp flexible scraper. Wash down if required and re-decorate.
- Cost: Economic repair.
- Pros: Retains period feel. Looks good initially. Piece of cake and quick repair.
- Cons: Might only last a few years depending on plasterworks original status.

Repairing Loose and Small Sections of Missing Plaster

Small areas of missing or loose plasterwork tin exist re-plastered, preferably using like haired lime based mortars and plasters. If these are non available to you, then areas could exist re-plastered using modern lightweight backing plasters and finish plaster (non protected ceilings only). Ensure that loose plaster and dust is removed and damp the area a fiddling before re-plastering. Ask at your local builders merchant for suitable plasters.
- Price: Economical to medium repair depending on size of expanse.
- Pros: Retains period feel. Fairly quick repair.
- Cons: Needs reasonable DIY Skills. modern plasters might be also 'rigid' alongside your old plaster leading to some slap-up. Might only last a few years depending on the surrounding plasterworks condition.
NOTE: Information technology is pop to meet folks recommending to completely 're-skim' former plasterwork with a thin 'veneer' of modernistic gypsum based plaster, say iii or 4mm thick. Whilst this can tighten up the plasterwork on an onetime wall, it can cause cracking later due to the relative stiffness of the new plaster in comparison to the underlying lath and plasterwork. Sorry!

Using a Thick Lining Newspaper

A sound (ish!) lath and plaster ceilings advent can exist improved greatly by the apply of a expert quality, thick lining paper. Lining paper has the do good of 'tightening' everything up and giving the ceiling an uniform look. It can then be decorated however you wish (ironically, some are painted to look 'distressed'!?!). It can be a practiced idea to scrape out and fill up cracks as No.2 before you glue a thick class of decorating lining paper over the plasterwork, as lining paper will 'shrink' into any cracks and unevenness. Re-decorate every bit you wish.
- Cost: Reasonably economical repair.
- Pros: Retains period feel. Could proceeds many more than years out of reasonable plasterwork.
- Cons: Relatively difficult on uneven surfaces. Won't stop further corking over fourth dimension if surface is all the same moving.

Using a 'Glue' Arrangement to Fix Sagging Plasterwork

Plasterwork can be 'glued' back into identify past drilling holes in the plasterwork, vacuuming out the dust and injecting a suitable tube type adhesive. The plasterwork is and so gently pushed back into place and supported until the adhesive dries. There is even a 'system' available in the states chosen "Big Wallys Plaster Magic", or you can see an video that explains the principles here:- Gluing board and plaster. A popular style is to drill 4mm holes, slightly countersink the holes, vacuum then squirt a thin adhesive into the pigsty followed by the drywall screw. Gently tighten the screw up into the countersunk plaster. Push up and support any sagging plasterwork showtime onto coating covered lengths of timber gently wedged up to the ceiling. The guys at 'Old House Online' accept a bully artice that explains how to glue up a sagging ceiling perfectly… How to fix old ceilings with glue.
- Cost: Medium to high price, depending on fourth dimension taken and plasterwork condition.

Removing the Whole Ceiling and Exposing the Existing Beams

Completely remove the lath and plaster, de-nail and clear abroad. Wire brush all plaster marks off the joists. Re-road any wiring, if required and repair any harm, holes in the timberwork etc. Clean upward and vacuum all surfaces. Leave as is or decorate with varnish, wood stain, or pigment. Ofttimes strips of plasterboard are fixed in between the joists on pocket-sized lathes nailed onto the side of the joists to hide wiring and the underside of the floorboards to a higher place. Usually merely used on ceilings (walls sometimes in the USA due to better sawn board).
- Cost: Economical to medium depending on timberwork condition.
- Pros: All the old plasterwork is removed and finished with newly decorated surfaces.
- Cons: Different await and experience, arguably only suited to certain properties and owners. Hard electrical wiring and limited option of light fittings.

Overboard with Plasterboard or Sheetrock

A lath and plaster ceiling can be left in place and 'over-boarded' with plasterboard, using long drywall screws through the existing board and plaster into the joists (not ideal only, quite usually done). Yous will hear this option discussed a lot and for many information technology is considered the 'only' pick, generally to avert the horrible mess created by consummate removal!
- Beginning you need to find what there is to fix your new plasterboards too. Ordinarily ceiling joists or studs in a wall.
- Detect them using the one-time way of drilling a line of holes 20mm (3/four″) apart where y'all suspect in that location is timber. You will experience the resistance when you lot hit wood, mark it and continue to notice the other side of the forest.
- Now you know how broad the wood is and where it is.
- Adjacent Mark their position on the wall, near 25mm down from the ceiling.
- At present you are set to over-lath with plasterboard (sheetrock) using long (60mm to 75mm) drywall screws into the timberwork where you accept marked.
- Board joints are so taped and filled if tapered edge drywall is used or skimmed with cease plaster if square edged boards are used.
An fifty-fifty better way to overboard a ceiling or wall is to 'batten out' offset. Hither, appx 25mm x 50mm battens are fixed apartment, underneath the existing board and plasterwork, by screwing through it, into the existing ceiling joists. The battens could also exist packed level/apartment using thin plastic or timber 'shims' equally they are screwed tight. Plasterboards are then fitted equally normal, (often incorporating, new wiring, insulation and a vapour barrier). This becomes a good repair as the battens secure the erstwhile plasterwork and the plasterboard gives a 'new' finish, plus the convenience of easy cable runs for new lighting.
- Cost: Medium to high.
- Pros: Effectively a brand new surface is created out of plasterboard/sheetrock.
- Cons: Potential problems with adding boosted weight or levels if in that location is a cornice. Loss of ceiling height. Loses that flow experience.

Replacing the Plaster and Lath with Drywall/Plasterboard/Sheetrock

Completely remove the lath and plasterwork and supersede with plasterboards / sheetrock. Once the existing ceiling is downwardly and cleared away, mark the positions of all joists and timbers onto the walls. Then gear up 12.5mm plasterboards to the underside of the original joists using 38mm drywall screws as normal. Utilise the marks on the walls to snap a chalk line onto the plasterboards, showing you where to identify the screws. Lath joints are and then taped and filled if tapered edge boards are used, or skimmed with terminate plaster if square edged boards are used.
- Toll: High. Removal of old textile, new boards and finishing makes this one of the most expensive options.
- Pros: Plasterboards/sheetrock are stable and very flat. A permanent repair.
- Cons: Loses the menses experience.

Re-plastering with Traditional Lime Mortar and Plaster

You may need access to the top of the laths to clear away the 'keys' or mortar 'snots' that were pushed through the gaps in the lath the offset time.

Working from above, gently remove all the accumulated grit, debris and one-time loose keys or nibs that build up over the decades or even centuries (dust masks essential!) Repairs can then be carried out using one of the diverse lath and plaster repair systems available. Often using stabilizing chemicals, wire mesh and adhesives or plasters, with the aim of reattaching the plasterwork below. For case; 1 organisation involves fixing a wire mesh to the inside edges of the joists just in a higher place the plasterwork and then applying adhesive to the plasterwork embedding it into the mesh.

Maybe y'all are just not cut out for living in a period house and would be better suited to a mimimalistic pad with the latest in smooooth applied science…. *laughing*.
- Toll: Horribly expensive, removal companies, estate agents, lawyers etc.
