The truth is that the fiberglass tape has its place, but – please! not on your sewing chalk.
Yes, I think it is controversial. And I have my (good) reasons.
In fact, people who use fiberglass tape instead of paper tape Drywall tape helps me to make a living.
As plaster finish and a specialist in the repair of plaster, I have thousands of dollars over the years to repair plaster seams with fiberglass. Thank you,people.
What happened? Gypsum seams need a sturdy belt to remain closed. Especially on the butt joints, the fiberglass seam will wiggle ever recorded so little time on the way to the finish line, and Presto! A crack developed to the center of the town.
The band has not broken. It's just that the mud plaster jacket does not go far enough – strong enough – to add the strength necessary to ensure continuous communication.
How can I say? Well,One thing I noticed that the tall, flush plaster seams tend to keep a band better recorded. With these seams, the jacket is thicker than mud, because it fills the valley, where the tapered edges of the cast come together. You get an additional robustness.
I understand that the beauty of the tape fiber glass. Fold down the crack and the mud "on it. No blisters, etc. as easy and convenient, especially for novices of the cone. And all do-it-yourself website and magazine articlepromote it.
Yes, it is more difficult to learn to make a paper tape used properly. For newcomers the cast, there are matters mud evenly on erasing the tape properly, avoiding humps butt joints, and so on.
These are the skills learned, however, and they paid big dividends when the job is finished and painted. Nothing is more annoying for the customers' lives in their new home / under see cracks developing in his new walls and ceilings.
As Isaid earlier, there is a place for the tape fiber glass. First, is the band of choice for seams in drywall plaster veneer. And 'what is designed in the first place. It works very well in this environment, because the plaster veneer is much harder and harder composed of gypsum.
But there's a place where the tape fiber glass can help in the field of chalk, and at the end of the day's repair job. Around doors and windows, cracks inThe plaster is generally. A little 'more movement in the formulation, and you will find these defects onooglike.
When I repaired as cracks, I want some more security. What I want to do is to use the tape – maybe three inches or so – short pieces of fiber glass and put in a bed of mud through the slot and parallel to each other. I cut the excess sludge
just as I would with paper tape.
When this first layer of the band is difficult, so I can see a line of paper tapejust above the glass fiber and centered on the crack below. Now I have a double safety glass for lateral force, and the paper to keep it close to the surface. Usually takes care of cracks or fissures, they are particularly worried. (If two or more coats topping, do not forget.)
I do the same thing, or a variant of cracks on plaster bad.
One last point. I stressed the hardness of the compounds used. For this reason, I was' hot mud ", an institutionCompounds most common form of patches to power.
If you are unsure of yourself and your speed would be best to use hot mud with a long body like an hour and 90 minutes. Mix small batches and do not forget to wash your tools correctly and pans between the parties.
There. It was not so bad, right?
