I built one of the quonset hut type buildings that is getting to be so
popular these days. I love the building. It is attached to the slab via a
connector plate, and red head anchors into the slab. I was told by the
building company to grout the area where the upright panels meet the
connector plate and over the anchor, feathering the edge to the outside.
This is the grout mixture recipe I was given.
1/3 Portland cement
In terms of acquiring this stuff, is it a Lowe's or Home Depot, or local
lumber yard. Aren't there different kinds of sand?
Any suggestions? The building is 34 x 20 feet. On each side there would be
17 "areas" to be grouted with a band of grout banded in between each "area"
Once it is grouted, should I seal it with something? Does the grout need
maintenance or replacing every so often?
Darn Perry - you've been a busy swamp-girl lately! LOL! You can use the
stuff at Lowes - but don't get the playground sand - get the mortar sand (no
clay - clean.) After you've grouted it - use a high quality concrete sealer
and don't be sparingly about it - cover it all. At the most - you'd have to
re-seal once every few years. Send me a pic of this project - I'd like to
see it. Or better yet - post it on abpf.
I built the building about 2 years ago. Just never got around to grouting
the connector plate. Siliconed it. But that's not a good thing. I am
having some shifting, some of it from temperature and when it rains
(constantly) I get some seepage.
I'd posted a link to the house on the other ng, I'll see if I can find it
and send it to you.
We get a lot of people that stop and want to look at the building. It's
exceeded my expectations.

Silicone will prevent your grout from adhering wherever it has been used. At
this point, you may be better off resealing it with a silicone. The failures
you are experiencing are not the fault of the sealant, but lack of sealant in
critical areas. Given a similar situation, I'd remove unbonded sealant, clean
the areas with lacquer thinner, soap and water, and dry thoroughly to remove
grease, etc. Resealing should then work quite well. Silicone sealants bond to
old material very well and ought to deal with thermal shifts better than a
grout. In areas where the sealant is absent, commercial mason mix from your
lumber yard should be a decent grout. HTH
