Before we even start it is important to note that every brand has their own information and you should rely on the manufacturer of the tile you intend to use.

Questions from Previous Thread


1. How much room should be left for expansion? I personally would suggest 1/2" gap at every wall and the garage door as well as around any cabinets, shelf legs, etc.

2. How long does the tile need to sit in the sun? As I mentioned in my article I do not believe this to be a silver bullet but I do believe it helps. There is not a simple answer as it depends on the sun etc. I would put it out in the hottest part of the day for a couple of hours at least. Get it as much exposure and warmth as you can, but get it installed before it starts to cool off.

3. Does every piece of tile need to be removed from the box and put in the sun? That is the best case, yes.

4. How long should I wait until I move the heavy stuff back into the garage (tool boxes, workbenches etc.)? For best results get it back in while the floor is still expanded.

Is there anything other than the above that I need to think of? Tile selection is important. My personal preference would be the TrueLock Plus Ribbed or Swisstrax Ribtrax as the product is capable of containing most of the expansion within the tile itself. If you are opposed to an open tile, I would suggest the use of an expansion joint, especially on south and west facing garages.

One of my garages faces south. The other faces east. I want the ability to leave the garages open when I want to. The southern facing garage will also have a 4-post lift installed in it next month. Obviously I would work the tile around the 4 post lift leaving the gaps mentioned above. The south facing garage and the door open is, to be honest, about the most likely case for a problem. You really need to consider the rib tiles.

Any advice other than the questions asked above would be great. I'm starting my project on Saturday! Take your time and place a phone call to the manufacturer of the tile you purchased. Make sure you have an answer from them on all of these questions.

Justin has some great tips with installing a modular floor this time of year with huge temp swings. We like to give this example of what we call Capturing Max Expansion for extreme installations
What do we mean by Max Expansion, let me give you an example;
If you take say a 30x30 floor and put it in the middle of a parking lot at midnight when its cool and park a car on each end...When you come out in the morning, the floor will be flat. When you come back at 1 pm you will see a rise in the floor, why? Because the floor can not push the cars out so the floor is taking the path of least resistance, which is up. Now when you come back at midnight, the floor is flat again as it cools and contracts.
Now lets take that same floor and park the cars on the floor at 1 pm ( floor is perfectly flat) . Go back at midnight and its flat, go back at 6 am and its flat, go back and 1 pm and its flat...why? Because you parked the cars on the floor right at MAX expansion and when it cooled, the floor can not pull the cars in and the RaceDeck powerlocks keep the floor interlocked.
So in your garage, you would want to install your floor at the hottest part of the day and put all your heavy objects back on your floor ( tables, lifts, cabinets, teool boxes, etc ) Again, we are always here to walk you through any stage of your install.

Thank you for the responses. I hope it will help others that may have similar questions.

I have ~1800 RaceDeck FreeFlow tiles going in this weekend. Even though this is an open tile, I will split the job up and focus on the southern facing garage first as this is where most of the heavy objects (tool boxes and workbenches) will go back into.

I get full sun for 4.5hrs on my parking pad so I'll just lay out the tiles there for a few hours before starting the install.

I don't have the lift yet, but did not plan on cutting around it. I definitely don't want to be disassembling a lift after installation either. I'll call RaceDeck today to verify this approach.

I followed all of the recommendations that Justin and Jorgen suggested this weekend when laying out my tiles. I am pleased to report that I have zero problems with buckling with my free flow RaceDeck tiles. The garage was left open for 3+ hours in direct sunlight (80 degrees, sunny, humid) yesterday without issue. I'll keep an eye on it and report back if anything changes, but I am not expecting any since I left a 1/2" gap all around and captured the max expansion. Thanks for your help guys!

Hello,
I am getting ready to install my diamond flooring in my garage here in Connecticut and have a question about expansion. My garage doesn't even come close to getting direct sunlight. It is located underneath my condo and it shares inside walls with my neighbors. Temperature stays pretty mild even in the dead of winter at around 55-64 degrees without any heating source. The floor is concrete. I'm wondering if I need to leave a 1/2" around all three sides of my floor or can I just leave a 1/2 inch on two walls where it would not be noticed?
Thanks.
Tom

Don't know. But I will say that in my case, I left the gap around all walls and I never, never, ever even notice it.

Or, some folks have hidden the gap with trim. I didn't bother. Looks fine to me.

You can't see the 1/2" gap at all. Mine has this black fiber stuff between the floor and the wall so it blends in with the tile.

Thanks for the replies and pictures. I'm going to follow suit and put the 1/2" all around.. A follow up question. I received my order yesterday and was wondering if anybody had any ideas on how to dampen the noise generated from foot traffic? i.e. like putting some type of subfloor paper? My garage is split in two levels so the car half I don't car, but the other half we walk on all the time.. Hard to judge with just a few tiles down if it is really noisey.. Thanks, Tom

I helped Slowbra install his and did not notice any noise when walking on it for the 5 hours I was in his garage. Maybe if your floor has low spots or is not level it would be noisey. However if you flow is fairly flat I wouldn't worry about it.

Mine's on bare concrete and has no noise any louder than if I were walking on the bare concrete. Don't know why others say they have the noise, maybe they have uneven or deteriorating concrete or something.

Regarding Noise on Tiles:

This is a question that comes up a lot. Generally you will not see it on an open tile like TrueLock Plus ribbed, Ribtrax and other similar products.

If you look at a typical 1/2" tile they are hollow and they can become an echo chamber. The open tiles for obvious reasons don't have that issue. With solid tiles on a 'perfect' floor we do not see the issue. IMHO there are not to many perfect floors, so things like landscape fabric as underlayment, etc are used to resolve the issue. PVC tiles is another solution

I have Gladiator/Racedeck (same manufacturer) flooring and live in the Sacramento Area where it can get 100+ degrees in the spring and summer months. A few days ago it was like 90+ degrees and i wanted to see what affect the temperature would have on my new floor. I did notice some very slight, hardly noticeable warping on about 2-3 of the tiles on the outer row and edging pieces in DIRECT sunlight.

I was worried that the warping would get worse but that was the extent of it. As soon as the garage door went down to block the light, the tiles flattened out. Of course when the weather gets that extreme, we button up the house.

I have a 1.5 inch gap on one side that I didnt bother filling in, and .5 inches on the other side.

Just wanted to write to say that direct sun in almost 100 degree temps was hardly a problem.

As far as noise...not a problem. Of course it doesnt produce the same sound as concrete. I dont know what the big deal is...

Well I tried laying out the tile on my pretty flat concrete floor and tried a row of them with 18 mil landscaping fabric folded in half and then another row directly on the concrete and another row on polyethylene foam. There is a significant decrease in noise with both the fabric and foam. The foam may have a slight edge but I like the fact the fabric can handle the moisture better. I really appreciate the feedback and suggestions and I'm pretty much convinced that it is worth the extra effort and cost to reduce the noise from walking on it.

hi

If you decide to use an underlayment, we strongly discourage polyethylene foam! it does not react well with gas, petro, chemicals and also traps in moisture. In addition, foam effects the expansion and contraction movement. Lanscape felt is much better if you choose an underlayment.

We also have our patented SHockTower flooring that not only offer anti-fatigue but also deadens garage sounds by as much as 30%
