Good day, my friends, In this video, I’m answering how to lime plaster a wall with one coat of lime base or lime finish, easy with plaster knowledge.
I'm answering a wonderful lady, Hally, who loves her husband so much she actually called me and asked to make a video to tell Milton, Happy birthday.
These guys are serious DIYers.
I was so moved by that expression of love. I did indeed call Milton and say Happy Birthday.
I kept thinking to myself, that’s the kind of wife all men should have and naturally vice versa.
Thus as I was talking to Milton, he asked about paging on a lime finish.
This reminded me of “old man Whitey” more than 35 years ago when I was hod carrying for him while working with a union plastering shop.
I kept asking, Old Whitey, when are we going to parge some walls?
Little did I realize, I kept using the term paging out of content.
Old man whitey used to smile and say, “so, you want to parge some walls, huh?”
Finally, one day, with a smile on his face while working at the Lorence Livermore lab project, I mixed his white coating plasters.
We had tons of time as it would take him two hours to spread the lime while I did pull-ups and twiddled my thumbs and asked a million questions.
I said again, what’s paging?
Whitey explained the benefits of parging lime over walls made of branches, bricks, rocks, logs, or anything else, saying the lime preserved the branches to protect occupants from bugs, like Maskitos, lice, spiders, ticks, and many other parasites not seen by the human eye.
He continued saying rats like warm rooms with food on the floor, but their little yellow teeth can’t chew through limestone. But, of course, the same applied to snakes and other curious critters.
I said, dude, why didn’t you tell me this long ago? His way was to just his smile. Moving on, in this video, I wish to explain a deeper knowledge of lime plastering.
When applying any limestone plaster.
BTW, Lime is healthy and an excellent mineral with health benefits, according to my pal, “old man Whitey.” But that’s another story.
To be up to codes and the recommendation worldwide, One applies the base coat of lime or even structo-lite plaster, waits until that sets.
Then applies on a different day, lime plaster finish over that base coat.
The reasons are many, but the primary reason is to first apply a strong plaster coat.
This is achieved with sand or any other aggregates to the base coat. For example, can you use fine or very coarse sand, horsehair, and the like?
Of course, you can; you’re housing your choice.
Then a lime plaster finish is usually applied over this base coat to make the walls smooth like glass.
This is for easy cleaning and collects less dust than a sand finish.
Can you just apply a base coat of lime plaster, trowel it, add extra sand, and create art and leave that? Of course, you can.
Do you need multiple coats of plaster? No.
Can you apply it thicker than the traditional one-sixteenth? Of course, you can. I have applied it up to half an inch and more.
Okay, moving on, can you just apply one finish plaster coat if you want really smooth plaster walls? Yes. If you are know-how, can you apply 1 to 5 coats of lime finish? Of course, you can.
When spreading over hospitals or schools, rules or compliance differ from that of an artist with a creative mind. By being an artist, you have no rules. You can do as you please.
However, if you’re going to apply a lime finish, say to sheetrock, for example, and you’re applying one-sixteenth to half an inch or more, this is where plaster knowledge comes into play, not code compliances.
Thus let say you only want to apply a finish coat to a bumpy room to smooth it out, and you realize the bag says apply one-sixteenth of an inch thick.
I would apply half an inch or more after applying a bonding agent to the sheetrock or painted surface.
Here how ole Kirk does it.
I apply my half an inch with as few troweling strokes as possible, and with just enough pressure to get it to hang, now I wait for it to darken just a bit, the means its setting.
Here’s the real art in knowing plastering materials. FYI, there are no tricks or secrets, just common sense that comes with practice.
When I place my wet trowel on this half-inch, and wish to Create a glass finish.
I first wet the setting finish coat with water, then I move the excess lime around to smooth out the lines. Too much troweling with brute strength instead of finesse the finish either separates from the wall, blisters, and or spider cracks, now you know.
