Hey all, in the spring time I am going to install an epoxy floor. Long story short I have a friend in the business and he is hooking me up with product to do a 3 part epoxy floor, base, flake and then a final clear epoxy. I won't give any brand names, but it one of the better industrial grade systems out there. I am in the maintenance industry and have had the same company install about 50,000 square feet in a high traffic industrial setting, and I have worked with them installing it on several occasions, and by worked with, I mean I watched and bothered the crew with endless questions. I plan on knocking it out in a long weekend come spring. One question I have, on my one year old poured garage, there are some good size expansion joints, two long ones cutting a 2 car garage into 4 separate slabs. So, I am thinking I would like to fill them in, obviously I want something flexible, don't want to undo the purpose of the joints, so I am thinking like a silicone or something? Any suggestions?

Hi,
Definitely don't use silicone as coatings won't stick to it. A better choice is a Flexible Joint Filler or Epoxy Crack Filler (not flexible, but much stronger) that we carry or other products other vendors may carry or Sikaflex which is locally available works well too.
A note though is that if or when the slabs move while the filler may allow for movement, the epoxy is hard and can crack, hence the reason why many people fill the joints after the floor is coated.

I used silkaflex. You need to put backer foam in or it will take a lot to fill. Use it warm and it flows nice. So not on a cold day. But it does make a mess so if you are not going to grind the slab make sure you put down tape. I decided to grind my floor due to timing so it took up the mess.

um, cant you have the buddy with the mystery hook up, get you a product to fill the joints
Yes, sorry, forgot to mention that backer foam often is required if the joints are larger than 1/8", as the filler will 'sink into' the joint otherwise.
If backer foam is not available you can also use sand to fill the joint as a support for the joint filler, just leave about 1/4" of depth in the joint to allow product to sit on the sand.

Flexible but hard. Too flexible and your epoxy will crack for sure. This is our offering (watch the video).

When the product in question inevitably wears from heavy foot traffic, specially near an entrance, what is the recoat procedure and how successful is it?
Thanks.

A topcoated floor can always be re-topcoated, hence why we often refer to topcoat as the 'sacrificial coat' If a floor is maintained when the topcoat starts to show signs of wear, in theory the floor will last forever.
But..in a residential garage setting it is highly unlikely that topcoat would wear out for many, many years. We have installs that are approaching 20 years old that show zero signs of wear.
Lastly we offer as a standard item our Ultrawear Powdered Metal non skid wear additive. This product extends the abrasion resistance 5x over standard topcoat, and is the same product we sell in car dealers and to the military. Most GJ members purchase this upgrade.

Degrease
Degloss (black stripper pad does a good job)
Wipe clean (dentatured alcohol)
Recoat
Harsh non-skids (silicas, oxides, etc) make the re-coat process a BEACH! So beware!
