Gemini Letters on Brick

I use Liquid Nails and never have a problem. When it's winter and I have an install I use DAP 3.0 Flashing caulk because of the super low working temps.

 

What size?
Blow out the dust and use a quality silicone for small/med size jobs.

 

10in. with stud mounts, silicone is fine.

 

Like Mike said, make sure you clean out the holes and use a good silicone or liquid nails and it will hold tight.

Lowes sells the Red Head adhesive for wedge/sleeve anchors if you are concerned with weight. It is a two part mix in the tip epoxy that you can get in standard single caulk gun style tubes. It is about $15 a tube but is mega-strong. Personally, I think that would be overkill on acrylic Gemini letters and going with off the shelf silicone would be best.

 

GE Silicone II available at Home Depot.

GE silicone is all i use on installs, good stuff

 

Just to pass off some info on what we use. we buy 100% silicone from cr laurence. It is freakin awesome. we buy it by the case of 30 comes to 3 bucks a tube instead of GE for 5-6. We use a ton of it, great stuff

Unless you oversize the holes GE silicone is fine.

 

I've done three 8" sets on brick, and several other sets in tile, metal and wood siding with just contractor grade pure silicone. They are all holding up well.
