Refinishing tips for existing epoxy floor

[tarmy]

View attachment 435107
I put down this epoxy about 10 years ago. It has performed well but it has finally started to get to the point of needing refreshing.

I am only going to redo the main exposed area shown here where the Tahoe sits. Basically to the mats on either side so I don't have a old/new seam showing.

Any advise on surfacing prep...should I clean and etch and coat...or some other better suggestion.

I am also thinking about filling in the expansion joints with the epoxy filler they sell at Home Depot. Thoughts on that idea?

Thanks guys...

Clean and degrease the floor. Rent one of the Clark floor maintaining machines from Home Depot, attach a 100 grit sanding screen and rough up the floor with it. Vacuum, wipe down with some denatured alcohol and apply the epoxy. For the prep that needs to be done you might as well do the entire floor.

Do Not fill your expansion joints with epoxy from Home Depot. You need to use a 2-part epoxy or polyurea joint filler that has a high elongation rate. These fillers are much more flexible than standard epoxy and will do a better job of letting your slab move without causing the coating to crack.

Thank you for the advise. The epoxy filler I am/was considering was the 2 part epoxy Rustoleum epoxy shield that HD sells...I like the idea of a firm but minimally flexible joint filler...is there a specific item or brand of polyurea?

Thank you for your time...

There are three ways to go. Cheap and easy, go to your local home depot and pick up some Sika product. There is the more traditional epoxy based joint filler that you grind down when you are finished -- be careful on this. Make sure it's specified for joints.

You can also use something like TrueLock TL829 Joint Filler. Here is the data sheet. http://www.garageflooringllc.com/wp-content/uploads/2015/03/TL829.pdf I like it because it is easy and effective. Mix it, fill it, use a razor to scrape off and extra and move on.

Thanks for taking the time to give me advise....will look into all of the above...but I tend to do it right rather than cheap or fast.

I went and explored your web site...I can't find the recommended TL 829 on it. I would like to buy some.
