Ornate Cornice and Ceiling Roses

Specialist Ornate cornice installed here. The bottom right cornice is 300ml in size and the bottom left cornice is 450ml wide. Very heavy stuff. The ceiling rose at the top is 660ml in diameter. The team did a fantastic job on this 187 year old house near Avoca Tasmania. Very proud of them all.


Plastering The Examiner Reception Area

This is the new Examiner newspaper reception area in Launceston. Sheets here are standups as the builder framed the walls to allow this to be done. Great effort by the PTC team to get this finished off fairly quickly.


Complete House Plastering. Bicheno

This is a rondo suspended ceiling on a raked angle from 3m down to 2.5m. Because usually 10ml plasterboard is used in residential housing, these metal battens, called furring channels are spaced at a maximum 450ml centres to comply with Australian Safety Standards. The blue colour board you can see in the background is for the bathroom, it is called “wetboard”, and is commonly used in any wet environments.

This is the finished sanded product. The angle you are looking at now between the wall and ceiling junctions was created using an adjustable PVC splade bead. This bead was then coated 3 times. 2 x base coats and 1 x top coat, this is also to comply with CSR Gyprocks warranty standards, trowelled any other way would void your warranty.

How To Install 6m Plasterboard.

Plasterboard Installation / Ceilings

Well then. You have become brave and decided well i can save some money here if i sheet my 12m lounge room ceiling myself. But your probably wondering well what do i need to do to install it correctly. Well here is some simple advice i hope helps you along the way. Firstly you need to measure you room and work out all the sheets you need to get, remembering the biggest plasterboard sheet size you can get is 6m long.

Once you have worked out how many sheets you need, you will then need to think about labour, as in how many friends you will need to get it done. If you have a plasterboard sheet lifter like the one pictured below, then you can get away with sheeting your ceiling with you and your mate. If you do not have one of these machines then the minimum you will need is 3 people, but 4 is recommended. You can how ever hire out these sheet lifters for around $50 a day so that is not bad value really compared to your mates wanting a carton of beer each and a free barbie.

Now to the sheeting part. Usually you will start against a back wall, never in the middle, sometimes you have too, but usually against a back wall. If your finish is a square set finish it is advised to take of the 50ml recess on the edge of the first sheet when you start, thus making your first sheet 1150ml wide and not the regular 1200ml. If it is cornice then you do not need to worry, as the cornice will cover the recessed edge. Before you throw up your first sheet you need to glue it with a product called Stud Adhesive. You can see some i installed on the ceilings below. Now the stud adhesive is placed on at 200ml, 400ml, leave the centre then 800ml and 1000ml. Look at the picture below to get a better understanding. The reason we do not glue the centre is because that is where we will be screwing the sheet, 2 x 25ml screws either side of the 600ml line. If i was to put glue there and then screw in the same place it would cause problems because as the glue drys it pulls the sheet harder to the battens and will pull the head of the screw through the paper faced plasterboard.

Now also if your room is longer then 6m you will need a butt join, that is where the ends of 2 sheets meet together in a ceiling or wall. Now as you can see, my example sheet below stops halfway between 2 metal ceiling battens(these battens are installed at 450ml centres for 10ml sheet and 600ml centres for 13ml sheet), the reason for this is so the ceiling can be backed blocked (will explain this in a later post) so it pitches up where the join meets. This allows the tradesman to trowel the butt join back to a flat level later. You will have to measure the plasterboard to make sure it does stop between 2 battens because it does not always work out that a full 6m will land in that position.

Now once its glued and cut to the right size you can throw the sheet up making sure you screw with 25ml screws for 10ml or 32ml screws for 13ml sheet, both ends of the sheet on each batten and 2 in the centre on either side of the 600ml line. Now this is the way its done in Hobart, Devonport and Burnie, but in Launceston it is screwed another way, but this way is fine, less sanding later.

Just one last thing. When sheeting ceilings that are bigger than 6m long, make sure that butt joins are staggered at LEAST 600ml apart from the previous sheet, you can have them inline if there is a 1200 sheet between them but sheets next to each other must be staggered minimum 600ml to make it easier to hide the joins when trowelling.

Ok, now you know how to throw up 6m long plasterboard sheets, enjoy and have fun with it, it is heavy work but it is not impossible for you to do on your own and save yourself 1000’s of dollars in the process. #plasterboard

Drywall Repair

Patch Drywall – Patching big holes in Plasterboard

Ok. You might have a patch like this and here are some basic drywall repair notes to keep in mind. Firstly find out what the cause of the damage was in the first place. If it is say for example water damage make sure the problem is fixed first before even attempting to patch or you will have to patch again later. Once that is sorted you need to cut out the damaged area into a nice square shape in which you will replace with new plasterboard. Once hole is cut put some timber blocks around edge of cut out hole so you can replace with new plasterboard. As seen below top left.

Now once you have sheeted the new plasterboard, you will need to tape this border with paper tape so it does not crack back out later down the track. Once you have done that, as it sets you scrape off any high areas in preparation for the second coat which i have done in the picture below bottom left. Again as this drys make sure you scratch/scrape of any high areas again in preparation for the top coat. Now your first 2 coats were done with a base compound as it sets hard and holds the tape in from cracking. The final coat is the top coat, which basically allows you to sand back the patch to a smooth finish ready for painting. I do recommend though when sanding always use a light to show imperfections up so you can patch before painting. #drywallrepair

How to plaster a wall.

How To Plaster a Wall – Basic Sheeting Help

Ok, a question that i get asked a fair bit is how do you install plasterboard on to a timber framed stud wall. Well the first thing you need to do in measure the height of your ceilings. Why? Because if its 2.4m high the you can order 2 x 1200ml wide sheets. If it is 2700 high you can order 2 x 1350ml sheets. Plasterboard comes in these widths only, 1200ml and 1350ml(wide not length). Now if your ceiling is 3.0m high then you would use 2 x 1200 sheets then get 1 more 1200 sheet that you cut in half at 600ml. Just take a look at the right picture, i am installing the 600ml wide sheet first then i will put a 1200ml wide on top of that then another 1200ml wide sheet on top of that, making a total of 3.0m high.As you can see, on 3.0m high ceilings you always start with the 600ml wide sheet first. Why you ask? This is so you can reach the join easy when you trowel it up, if you put it near the top you will need a ladder to reach.

Anyway, before sheeting the wall you need to put insulation in, if the client wants it and you need to put the stud adhesive on the wall prior to putting the sheet on. Now a sheet is normally 1200 wide so in this case you would put daubs of stud adhesive at 200ml, 400ml, 600ml and 800ml on each timber stud. The top of the sheet is screwed or clouted and the bottom of the sheet is screwed or clouted. Do not put screw or clouts in the middle of the sheet. Later they will break the paper surface of the plaster and show through. If your sheeting big sheets like a 4.8m long or 6.0m long sheet, you can put some screws in the middle to hold it back till the glue sets. But remember to take these temporary screws out after and just plaster the little hole up, if you leave it in it will pull through the plaster down the track.

Well i hope this helps you DIY types and remember, the first thing you do before sheeting any wall be it timber or steel or brick is to measure the height of your ceiling so you know the right type of sheets to get. #howtoplasterawall
