Getting quotes to replaster

[Flippy]

Howdy -

We are looking at getting quotes to re-plaster our 18 year old pebble tech type finish. The first bid I got was around what I thought it was going to be in terms of cost. The contractor said they should be able to plaster over the old pebble tech without having to strip it first. Striping it was another 2K dollars. Is it possible for them to go over the old without compromising the new plaster? The old pebble tech finish seems to be bonded well to the gunite shell. The issue we have with the current plaster is a lot of the pebbles have dislodged and the bottom of the pool is extremely rough on the feet in a few areas.

Thank you

If pebbles are dislodging how do you expect new plaster to adhere to loose pebbles?

The $2K for a full chipout is well worth the investment.

Specify you want the chipout to use flat chisels, not pointed. Pointed chisels damage the gunite.

That is why I am asking. I would hate to spend 7K on new plaster only for it to fail within a few years.

What will your new finish be?

It will be another pebble type finish. I have another contractor coming out on Monday for another quote and I will see what he says.

Ask the first contractor what he is planning on doing when the plaster meets the tile line, lights and return lines with the second layer of plaster.

 

[Flippy]

That was my thought how will it line up with the tiles, returns and fixtures.

I think it would be best to do a full chip out to be on the safe side. I just don't see new plaster doing so well on the old.

Second contractor came out this afternoon and said they only chip it all out. Also said tile would most likely need to come out as well. We will see what his quote is later today.

This is what a full chip out looks like with when using flat chisels.

Ever see a pool that has had the plaster removed by sand-blasting? Just curious …

 

[AQUA~HOLICS]

Yes I have, a few years ago they were very common for a while with some of the re-plaster companies but I haven’t seen many lately. This may be due to its inability to remove an exposed aggregate plaster.
I feel these finishes were better prepped for the re-plaster application on the shell than jobs done with chisels due to the amount of plaster that was removed and the texture that was left behind.
Two negatives with pointed chisels are the amount of plaster left behind and the amount of Shotcrete removed.
I had conversations with my steel engineering firm and they were concerned about how much Shotcrete was being removed when pointed chisels were being used.

This may be due to its ability to remove an exposed aggregate plaster.

Did you mean "ability" or "Inability"???

Thanks,

Jim R.

 

[AQUA~HOLICS]

Inability, only speculating on the reason for not seeing it as often. Sorry for the confusion.

 

[Newdude]

Sorry for the confusion.

Lord knows we ALL get autocorrected or fat fingered at times. THANKS for all you get right.

I have more typos, bad grammar and misspelled words than all of our TFP members combined.

I was not trying to be picky, but just wanted to make sure everyone knew what you meant. I had assumed you meant inability, but wanted to make sure for anyone reading this thread later.

Thanks,

Jim R.

I do appreciate bringing it up, I try to re read everything before hitting the post reply button and still things get past. I never thought of the question in a negative manner.
