Need Suggestions On Specialty Caulking.


Looking for suggestions on a caulking situation I have.

On the interior of my project I have a situation where stone flooring meets wood flooring. At the stone edge I have installed a Schluter strip to protect the edge of the limestone. Then, I have a 1/4Ē expansion gap before I get to the Wenge flooring. I read the expansion tables of Wenge and have determined that the width of my flooring will require a 7/16Ē total expansion in the event that the hardwood has a 1% moisture variance in EMC. I have divided that expansion in half since I need expansion at both edges. The Wenge flooring is pinned between two areas of stone flooring.

Now to my question:

I would like to install an architectural grade flexible caulking that will act as my expansion joint. I would like the caulk to sit flush with the flooring and be durable enough to walk on yet just supple enough to allow for movement.

I would like a colored caulking material since I will not be painting it. Dark brown or black would be best.

Many flexible caulks can remain slightly tacky and attract dust and dirt. I would like to avoid this.

Can anyone suggest a product?

Thanks,
Eric

That's not a caulk-friendly situation. You need a transition strip to allow for that sort of movement.

Yep, so true. Thing is that everything in this project is flush. It’s a $15million project. It’s been really fun and challenging. Some very unique challenges too. Anyway, any thoughts on a caulk product?

No, itís just that youíre asking for a lot here. The biggest problem being the dust magnet issue. Iíd prob look at something with a urethane for this application. Tower Tech 2 would work, but it will attract dust. You can check into Sika products. No matter what itís nit going to be flat, it will have a slight concave to it. Nature of the product. Youíll want to use a backer rod so the bead forms and hourglass shape otherwise itís not going to last through expansion/contraction cycles.

Re: Need Suggestions On Specialty Caulking.


Would a flexible epoxy product work....poured into the gap and allowed to self level?

Could be tinted also.

Just thinking out loud.

Thanks,

I was leaning towards Sika although I was hoping for a water clean-up product. Great tip on the backer rod.

Flexible epoxy:

Interesting thought. What name brand? I know most epoxy is pretty rigid but if there was a flexible one...might be the way to go.

Frog tape on either side of the gap. Wipe the tape edge with a damp cloth to activate the agent that stops bleed through and you should be able to get a clean joint without making a mess on the flooring.

I would call these folks. I use their products fairly often.

What about a urethane flexible grout product? Might something like that work?

Thinking way outside the box...caulk, let dry, then apply a grout colorant. Rinse and sweep several times after that.

(I told you it was outside the box...)

Look at Tremco caulks. Often what is spec'd (or comparable) for concrete expansion joints at walkways and such.

Re: Need Suggestions On Specialty Caulking.


I can't comment on it's ability to not attract dust, but I've used Pergo's acrylic caulk before. I almost always use (just) a joint between my tile and wood flooring because it's clean and less of a trip hazard.

Last job I filled the 3/16 joint between the marble and engineered flooring with the same Mapie Flexcolor CQ grout used on the tile floor. It's not as flexible as a caulk joint, but it's not rigid like old fashioned grouts.

Re: Need Suggestions On Specialty Caulking.


After some good head scratching last night I think I’ve decided to use Dap230 caulk which is paintable. Once the caulk cures I’ll put a couple coats of clear Diamond acrylic over it. Should be durable and dust resistant.
