I am adding a few masonry blocks to the top exterior wall corners of my
home. They will be setting directly on top of existing masonry block
construction..probably 2 or 3 each way at the corner for a
Spanish/territorial style affect. The city inspector says I should take
about a 24" piece of rebar at each corner and drill into the existing block
base...epoxy the rebar into the corner section...and add the two short
'steps' of new block over/around the rebar corner anchor.
What he didn't say was what type of epoxy to use...HB and Lowes only have
these little ...looks like one shot...tubes ?
Anyone know what type of epoxy...?...and can I buy it in like a quart or
gallon size set up rather than 3 or 4 dozen of these little 'applicator
Thanks, Tim R
Those tubes are the easiest way to apply the stuff by far. You don't
need a hell of a lot as the hole size is just a small bit larger than
the rebar. For such a small amount of added block length, I'd figure
one or one and a half tubes per corner.
Other than that, buy a quart with catalyst and pour it in. Anything
WEST System advises on their web site is good.
Try your preferred phone listings for masonry suppliers or
concrete products. I always get mine from Eagle Concrete
Products, but of course, I don't have any idea where you are located.
Epoxy for masonry comes in a variety of styles and containers,
from 2-part caulk guns (which requires a $150 caulk gun) to
single tube with two parts and a mixing nozzle, to 5 gallon
buckets with another bucket of catalyst. And those buckets have
flowable, trowelable mixtures.
Real stores have real variety. Home stores just have popular
Here are a few of them:
You should be able to find a larger container of epoxy at the same
store. There's no logic to the way they organize products at the borgs,
so ask. They put stuff in the strangest places.
Look for a product that mentions masonry in the application list. Since
this is not a visible installation, any old epoxy will probably do, but
I always look for a product that says it's designed for the task.
You won't need nearly as much epoxy as you think. The hole you drill
should be just barely bigger than the rebar. The epoxy ends up as a thin
coating on the outside of the rebar. The one-shot container might be
I would suggest SIKA Anchorfix #1 (fast set; 5 min) or #3 (slow set;
works in a standard caulking gun, comes with 2 nozzles.
Be all ready to install rebar if you use #1, the stuff will harden in
the nozzle if you hesitate for a few minutes.

both are available at HD (SoCal) with the lumber / building supplies.
re: Be all ready to install rebar if you use #1, the stuff will harden

But what happens after you install the rebar..won't it still harden in
What am I missing here?
Yes, all mixed epoxy will harden in the mix nozzle or on the mixing
The trick is to dispense, mix & place before it hardens.
The SIKA AnchorFix#1 hardens in a matter of a few minutes (depending
on material & ambient temp)
After you're done the hardened screw on nozzle becomes a cartridge
