I had my chimney tuckpointed a few years ago and the guy gave me the
same spiel. He applied a sealant.

Well, 3 years later and all the pointed mortar has fallen out and I'm
doing it myself this time. So I guess my comment would be, they've
been building masonary houses for hundreds of years and didnt use
sealants back then so what has changed to make them necessary now? It
obvoisuly didnt work in my case.

Back to your question. I was just in Home Depot buying new mortar and
saw gallon jugs of Masonary/Concrete Sealant sitting on the shelve
next to the bags premixed mortars. I'd use that. I'd never use
Thompsons due to past bad experiences.

Last November I had the roof stripped and shingled and the chimney
re-built
above the roofline and the guy that did it said I should get up there and
waterproof the chimney in the spring when it's warmer. Well it's spring
and
I want to do it but I was wondering what I should use? I have used
Thompson's in the past(mixed results) but was wondering if that is the
best
stuff to use. What do the Pro's use? Thanks for any help.....


I had the chimney COMPLETELY torn down to just below the roof line and
re-built with new brick,flashing ect. The bricks on the old chimney were
like yours was falling apart...700 bucks well spent..IMO...
