Wall plastering in Taiwan: Plaster sets VERY fast (10-15min). What can I do?

I've used drywall compound on plaster in the past with no problems. But it can't be the ready mixed stuff, get the power and mix it yourself (also cheaper). If the house continues to settle/move there is no product out there that will keep the crack from happening again.

The trick is to make a slight gouge in the wall with the crack, just putting a bit of compound over a hairline crack won't hold enough, with a pointy object or screwdriver trace the crack until you get a little valley, then patch with compound, sand, repeat if nessassary. Sanding is key here, good rule of thumb, if you can feel ridges with your fingers, you'll seee them when you paint.

Last, i would not use caulk as someone suggested. Caulk will indeed move a bit with the house, but you can't sand it flush, so unless you get it perfect you see it when it's painted...

This question is very similar to this question:

How Do I Fix a Hole In Drywall

There are some good answers posted, so it is worth a read.

To build on those answers for this particular case, I would recommend the medium size hole fix. The only difference is since the hole is on the small side, trying to screw the new 3" circular piece may crack or break it in half or in pieces, so my recommendation is to glue it to the strapping or backing material using gorilla glue or similar. Just make sure the new piece doesn't stick out of the existing wall. If you can make it slightly less than the existing wall, that would be optimal, and then you can just fill in the depression with mud/spackle.

If the plaster is painted, you can use mud to fill in, it doesn't have to be plaster as the paint will cover it over. If it is unfinished plaster, then fill in with plaster as the finish will be the same. It looks to be painted, so standard mud/spackle should work out...

For drilling stone or concrete you'll want to use a good quality masonry bit, and a good rotary hammer drill.

As Shirlock points out quality is important here, so you don't want to skimp on the tools when drilling stone or concrete. You'll want to look for a carbide tipped masonry bit, as these tend to last a bit longer than the typical masonry bit. You'll also want to make sure the bit is rated to be used in a hammer drill, since a standard bit can easily be destroyed by the hammer action of the drill (causing personal/property damage and/or death).

If you're doing a small job and don't want to spend the money on expensive tools, you should be able to rent what you need from a local home center (Home Depot, Lowes).

A hammer drill is necessary when drilling stone or concrete, since grinding away the material with a standard drill would take far too long. A hammer drill works similar to a normal drill, but with an added mechanism that "hammers" the bit...

Every dream that I dream
Seems to float on by
Like a cloud in the wind
Way up in the sky
Every move that I make
Seems to be the wrong way
Like a cold black night
After a summer day

What can I do
What can I do
Nothing to say but it used to be
Nothing to say but it used to be
What can I do

You still play my guitar
With a smile on my face
Now everything's changed
My whole life's rearranged
From the day I was born
Sidle Jinks was my name
Though I tried and I tried
That name still remains

What can I do
What can I do
Nothing to say but it used to be
Nothing to say but it used to be
What can I do

What can I do
What can I do
What can I do
What can I do

I hear voices all singing
But no one is there
It's a ghost of my life
Bringing past tense to mind
Lokin' key inside me
From the freedom and sin
Oh come...

There’s a lot to be said for knowing how to plaster a wall properly, both in the amount of time and effort it can take you, not to mention your level of satisfaction with the finished result.

The last thing you want is imperfections on your wall that are going to bug you for years to come so first off, make sure when you plaster a wall that you follow the six stages of plastering in the correct order, that you keep your tools clean and have the right kit to hand.

It’s also important to find the right trowel for the job, making sure it’s clean and rust free. Then, when you apply your plaster, ensure you have your trowel at the correct angle to the wall and remember to keep applying firm pressure throughout to get rid of any bulges and ensure a flat, even surface.

But that’s just for starters…

We have put together the ultimate guide to plastering a wall which will take you through the stages you need to follow, show you what you need and how to do it –...

Ok, first - joint compound & patching plaster could refer to the same products. The term 'joint compound' is referring to a "mud" that is used in construction when filling in the joints or seams of sheetrock panels. The compound normally comes either premixed in a 'drying compound' or in a bag as a 'setting compound.' Plaster of Paris is another product altogether & not what you are looking for. If your home is actual plaster-and-lathe construction, I would reccomend using the setting-type compound which actually 'sets up' like concrete or mortar. Hopefully, you have flat or smooth finished walls (no texture). This will help in the repair process.
Drying compound is much softer and won't hold up as well as the setting compound. One note - the setting compound comes in several formulas - each one is labeled by the time in which the 'mud' sets. - this could be 90, 60, 30, or even 15 minutes! So be careful to look for the number in the middle of the bag &...

DIY Plastering tips for stress free plastering!

For all Aspects of Plastering

1. Prepare & Control the Suction

Control the Suction - if the wall is too dry the moisture will be sucked out of the plaster you apply and it will become too firm to work properly. This applies to both the backing coat & the skim coat.

Backing Coat Plastering Tips

2. Using a Sand based backing coat.

Sand & cement (with plasticiser) can give many advantages for the beginner:

gives you all day to work with it - it sets overnight so no time pressure.is easier to float - so if the ruling off with the straight edge still leaves holes or leaves the surface uneven - the float will take care of it.

3. Apply Two Coats

A very thin 1st coat – just to ensure it sticks and is properly pushed into the wall with lots of pressure.

This ensures it will not fall off later, and allows the 2nd coat to be applied - with just enough pressure to ensure you apply the...

Plaster vs Drywall, which is best? As many of you know by now, I’m a stickler for historic accuracy when it comes to remodeling. Some might describe me as obsessive or possibly deranged, but they’re just haters. I prefer to be described as “particular”, or “having high standards” – that just sounds less likely to get me locked up in a padded room. My “particularities” led me to choose plaster instead of drywall when we had to replace several walls in our 1930’s vintage home. Sure, drywall guys will tell you they can match any texture, but drywall is still very different from plaster. Before you dive into hanging drywall in a vintage or high-end home, consider the alternative of plaster.

Plaster vs Drywall

These days you have two general options when it comes to finishing walls: the first is standard drywall, which we’re all pretty familiar with. It’s everywhere, and so is the dust from installing, sanding and finishing it. Drywall consists of gypsum sheets...

Dear AT,

I'm moving into a restored Victorian place and it has what I believe to be plaster walls. Thankfully they aren't the lumpy sort. I've had trouble putting nails and screws in plaster before. Usually, the wall crumbles and the screw or the nail bends.

I just bought some shelving and curtain rods and I can't risk the crumbling b/c i have very limited space to work with. How do you do it correctly?

Dear mg,

No matter what you're trying to hang, be sure to first drill a very small pilot hole. It's these small stages of drilling that will help your walls not crumble. Also check out if you have picture rails built into the corners of walls/rooms. Many great, old apartments have them, so go ahead and use 'em!

Plastering walls is a very easy task, provided you know how to mix the chemicals to achieve the appropriate consistency. The plaster should support the surface where it is applied. After applying all the three coats, the surface should be smooth and suitable for applying wallpaper or paint. The task of plastering walls involves the application of three coats - the base (first), brown (second) and final coat. To start with, coarse or rough coats are applied to the wall. The base coat is a mixture of lime or gypsum, aggregate, fiber and water. The aggregate usually used in the base coat is sand. The work of plastering a wall can be really messy if not handled properly, hence it is advisable to work it up the plaster carefully and steadily, so that it does not dry up in the mid of the process.

Plaster is a composition of lime, sand and water used to coat walls and ceilings and allowed to harden and dry. It is a building material similar to mortar or cement and is used as a layer on an interior wall or as decorative moldings on ceilings. This method is called plastering and is used in construction of buildings. During construction people tend to give a lot of importance on the decorative aspect of the house and forget the most integral part of the house being the walls and its durability. Plaster walls tend to develop stress-cracks on walls and ceilings over time and professional help needs to be taken to repair these cracks or it could result in extensive damage to the building. This ancient material though used in interior wall finishing, have many issues along with its benefits.
