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

Use angled sanding block. Plaster Repair

Hi All.

Just a quick one here on sanding and plaster repair. If you remember back to last posting i was talking about taping in internal angles using paper tape. Well as you can see on your left the wall and nib wall are now got a coat of paint on it. But before i painted i had to sand this area. After i used my dustless sanding machine you still have to go through and BLOCK sand the internals and anywhere else the machine could not reach. i.e around the power points etc.

If ever you end up doing this for yourself, make sure you buy the angled sanding blocks as you can see in the images below, not the straight edge ones, because with the angled sanding blocks you will not dig out the plaster on the other side of the internal as your sanding it. If you use a straight block it hits the other wall in the corner and digs out the plaster, leaving plaster repair work to be done.

Anyway just a quickie

Square Set Openings

Here is a new square set opening. Framed with external angles, 2 x base coats and 1 x top coat. You MUST scratch/scrape plaster down between each coat, usually just before it fully sets.

There’s the square set opening in the background with the external angles on before it’s trowelled. Remember to use a level and builders square when installing or they can look really bad when painted 🙂

Taping in internals by hand.

Right. i am at work at home and i’ve just taped in the corners. These are called in the trade internals. As you can see on the left photo that is a taped in internal. you put the plaster on both sides then you put over that the paper tape which you fold(it has a fold line in the centre of it). Once you have that in you blade it off with a 3 inch (angled) broad knife so you don’t spread the plaster to wide. And that’s it you have a taped in 90 degree corner which later on you top coat with a 4 inch blade and a special corner tool. i will explain that later.
cheers
phil

happy taping
