Latex Filler Compound Available In U.s.?

I am getting ready to canvas and fill a 16' 1958 Old Town Otca and wanted to use a latex lagging compound for the filler. I have to work in an attached garage and cannot have the lingering smell of a traditional oil based filler around for the weeks it takes to cure (I may not smell it, but the wife will and .....). Are there any sources in the U.S. for a filler similar to the Bakor or Rollins I have been reading about? Or should I find a source in Canada willing to ship it? (ouch)

I have also read about using something called Mastic - is that the same as a lagging compound or different? Will any Mastic work, or is there a specific kind/brand that works best?

I am a newbie to canvas canoes and appreciate all the help and expertise on the forums. I have searched the forums several different ways trying to find an answer before starting a new thread and could not find the answers. Thanks in advance for all the help.

 

There is a wide-ranging discussion of filler possibilities here: http://www.wcha.org/forums/index.php?threads/canvas-fillers.14814/
I'm a fan of the pipe lagging compounds, especially Bakor 120.09. I believe it is made in the USA. Shouldn't be too hard to find. Call a local sheet metal business or a fire suppression system installer or, better yet, the business that supplies them.

 

I looked up the Bakor - it is only sold in Canada. The company that carries it (Henry Co.) has offices in Canada and the US, but will only sell the Bakor lagging in Canada. Same with any sources I can find for the Robsons Mastic. I had found a 2 year old discussion on the Orca Boats YouTube channel comments page that seemed to say I could order the Robsons direct from Canada, but the shipping would be very expensive. That is why I was hoping for a domestic alternative.

 

Here's a link to a MSDS from a similar product from Childers. I note that it says the product is hazardous to the marine environment, but that would be only before it is cured. Airborne dust is also a risk, but I haven't found it necessary to sand the coating after curing and there is no dust during application. https://cdn.shopify.com/s/files/1/0...a-mv1-chil-seal-coating-and-adhesive-msds.pdf

 

I nade a mistake. The product I linked to is not a hazard to the marine environment. When I wrote that, I was looking at a MSDS for Childers Chil Seal CP-50A MV2, a slightly different product. I suspect that either one would do just fine for a canoe.

 

There is some confusion here.

Childers makes two products that seem similar:
CHILDERS CP-50A MV1, a/k/a CHIL-SEAL® CP-50A MV1 Coating
and
CHILDERS CP-50A HV2, a/k/a CHIL-SEAL® CP-50A HV2 Coating

I cannot find a Childers Chil seal CP-50A MV2

The link in the post above is for an MSDS that seems to be out of date.

Both CP-50A MV1 and CP-50A HV2 have similar warnings about uses in an aquatic environment. CP-50A HV2 seems somewhat more hazardous; both direct safety measures while using/applying.

*******************************

I have not found an MSDS sheet, so entitled, for this product..

For a product description, see: http://fosterproducts.com/product/cp-50a-hv2/ and click on “PDS."

If you are thinking of using one of these products, please read the Safety Data Sheet for each in its entirety -- the C&Ps above quote only a small part of the sheets.

 

And there's the voice of experience, Greg. In what way did the Childers CP50 fail, Dan? I have never laid eyes on the stuff, just went searching on Google for a product that might be similar to the Bakor 120.09. I did notice in the search results that there had been several discussions of the Childers material on the Wooden Boat forum.

 

Latex filler? Lately I've used interior/exterior sealer/primer. I get mine from Sherwin-Williams. It can dry quickly. I mix exterior latex spackle lightweight for the last coat or two. Pro-block and pro prep are two names that come to mind. They also have a product that is caller filler and it is oil based. My mentor didn't fret as much about fillers. So, eventually I quit worrying about it. I've have traditional filler give me trouble. I know of one canoe that was successfully done by simple painting with varnish repeatedly.

 

The fellow in this thread used the Childers Chill-seal for his boat, you could ask where he got it. Sounds like he had good results.

I found it available from this company which has locations all over the US. For $25 a gallon it might be worth a try.
