economical densifier / sealant suggestions

[shaggyant]

I'm looking to put some kind of denisifier / sealant on my new garage floor.
I spent my money on the 34 yards on concrete and 110 sticks of 1/2" rebar and I don't have a bunch left for the sealer.

So what's the best densifier / sealant that I can get 1800 square foot of coverage for about $500 or so? Thanks in advance.

I am currently looking at the Concrete Sealers USA PS104 lithium silicate sealer and densifier.

You can spend less than that and get a great densifier.

The HD40 is $418. Is this all I need to densify and repel stains? Do you recommend your densifier before your hd40? I didn't get that impression when reading your website. Is your HD40 going to be oil repelling? I don't see that specifically called out in the description?

The other brand said I need to wait 28 days for curing before application. Is the same true of your products?

I also looked at the ghost shield 8510 but that was going to be over $1k.

If you predicate the HD40 with our HD37 it does much better against oil stains.
Remember, all these products are PERMEABLE. They allow the slab to breathe.
Therefore oil, if left long enough, can make it through, but will be greatly minimized. These products (densifiers) can be applied as soon as you can walk on the slab. Also... if your slab is well power-troweled it will help these products do a much better job.

If you want better protection against oil look at out HD6525MMA or SEC SEALER.

We have some great densifier and sealer combinations:

If you are trying to protect from oil stains I would do TL37 and Ghostshield 8505

For basic protection I would do TL39

So the HD37 and the HD40 are both densifiers? Why the need to use both? If I'm doing two coatings would I be better off to go with the cheaper HD37 and then something that only seals the concrete instead of applying another densifier?

The 37 is concentrated. It has more active ingredient. If you want more protection use it if not don't use it. The 40 does pretty well all by itself, when applied correctly over smooth power troweled concrete.

In my shop I just finished using the hd37 and hd40. I did just under 2600 sqft. I was sent 7 gal of hd37 and 7 gal of hd40. The first and only coat of the hd37 took almost 6 of the 7 gal. I followed that up with 4 coats of the hd40, which also took a total of 6 gal.
I am happy with the results. I used this combination of products because I plan on using welders and cutting torches over the floor along with other activities. All included I would say I was just under $0.40 per square foot. This includes all supplies, materials, and burnisher rental.

If I go the HD37 then HD40 route how many gallons am I looking at of each component? Based on other replies I'm thinking 5 gallons of each? Will one hogs hair pad last for the whole job?

Your sig line mentions a Garage Journal member discount. If it's a 10% discount a new membership would pay for itself...

So, I've got my HD37 and HD40 and I've waited long enough for the floor to cure. I need a little more specific instruction on the application of this stuff. I've emailed Scotty but since he's in Florida he's probably in a hurricane right now and can't answer.

Has anyone else here applied this combo? I need to know if I should wash the floor before applying the HD37? How long after applying the HD37 until I can apply the HD40?

Thanks in advance if anyone can help me get this done this weekend.

Yes, make sure the concrete is clean. When you apply the densifier, do not leave any standing puddles or it will dry into a white residue that is difficult to remove. It's best to wait a week after the densifer is applied before you apply the HD40. The reason is that a densifier reacts to the concrete and it takes about that long for it to go through the chemical process of hardening the concrete and filling the pores. This will prevent the HD40 from penetrating deeper into the concrete and keep more at the surface, thus improving your coverage rate.

Apply 2 to 3 coats of the HD40 using a microfiber pad. Again, do not leave any puddles. Once it has dried, you can then go over the surface with a hogs hair pad using a high speed burnisher.

Awesome! Thanks.

I was planning on using a pump up sprayer to apply the densifier. Is that a good method? Should I use a roller to even it out? I'm not sure how fast this stuff will soak in and if back rolling it with a paint roller will help or hurt.

I used Ghostshield products but the pump sprayer worked great. I will agree with the keep puddles away. It took longer to roll the puddles out that would form than the spraying took.
I think you will be pleased with the results. Only thing I did was acid stain for color. Didn't want 2700 square feet of gray under foot. Also using different colors stains in a random pattern means any stains that do occur over the lifetime will blend into the patterns of color.
Good luck and let us know how it worked out for you.

The sprayer is great! The "soak in" timing us dependent on the porosity of your floor. Should take no longer in 15 mins. If does (not a bad thing) just mop off any excess.

Or a lot lot less... I've had good luck with Eagle Natural Seal.

It's about $80 for a 5 gallon pail at Home Depot. They'll ship it to your door for free.

Hello Shaggyant;
I just applied the HD37 yesterday to my 2000 sqft power troweled floor. The floor is new so I just blew it out with a leaf blower and vacuumed the saw cuts. Then washed it down and scrubbed with Simple Green and rinsed well , then let it dry overnight it was 90 degrees here.

I used a cheapo multi-purpose sprayer, spraying each saw kerf section about 12' x 12'. I sprayed half the section and spread out the HD37 with a microfiber pad sprayed the rest worked it in no puddles.
I tried to judge the amount of product going down and the first section 36'x8' I only used less than 1/2 a gallon so I went back over with a second coat. It had already dried a bit for the second coat again it was like 90. Doing the rest I sprayed a bit more so I had a wetter surface with the rest, but still had enough product to do two coats. I had 5 gallons and when done doing 2 coats have about 1 gallon left over.

The tech paper says one coat as well as Scotty says one coat is sufficient. I think I needed to get a bit more material down let it sit for 5 minutes then work it in. It was warm so product was drying a bit quick.
Took me 2 hours start to finish just me working it with a 10 minute water break. Really easy to do and 5 gallons should be plenty for your 1800 sqft.
I was going to do the HD40 today ( one day after HD37 ) I think someone else on GJ did that but I might wait a couple days as SHEA recommends.
Good luck

Yeah, I was going to try and apply both coatings in one weekend but at the last minute I decided that waiting a week between coats would be easier on me and probably better for the floor. Taking your time generally ends in a better result. The rental place was fine with me scheduling my rental another week out. They made it sound like a high speed burnisher wasn't exactly a hot item for rental.

Thanks for the help everyone! I washed the floor this morning and I'll spread the HD37 tomorrow and the HD40 next weekend. When it's done I'll post photos.

The HD37 densifier is on. I used a pump sprayer and the five gallon bucket gave me two and a third coats over 1800 square feet. Used the leftover after two full coats in front of the roll up doors. It was drying quick there because of the sun shining in.

The HD37 is pretty thin and doesn't really have any odor to it. Heck they could have filled a bucket with water. I bet it would be hard to tell the difference when applying it.

Edit: after drying for three hours it looks exactly the same as it did when I started. I guess that means it was a success.

That's what I was thinking " Look I paid for a bucket of water".
So you going to wait 7 days? I'm having a hard time want to get this done I have been doing other things for 3 months trying to decide on a coating.

I am waiting until next weekend. I do want the floor done so I can move my stuff in before the weather turns but my day job is too demanding for me to spend a day buffing floors during the week.

I have the rental set up for me to pickup Saturday at 15:00 and have my wife return it Monday morning. I am figuring on applying Saturday morning and buffing starting Sunday morning.

I have no idea how long the polishing process will take or if there is a danger of over polishing. Maybe someone on here knows how much polishing is enough?

No water, lol. All densifers look like this. The first time I played with densifier I had similar thoughts. Put your ear to the ground after you apply, you can hear it snap crackle and pop and of course, if you were to polish it, much faster results with densified concrete as it has been made more dense (hard).

 

[shaggyant]

Scotty,

Any specific recommendations as far as polishing the HD40? I want to make sure I don't polish too much of too little. Is there a way to tell when it's good? Now that I am here I kind of regret not getting the cherry wax. Does the wax make it slippery when wet? Slippery is something I'm specifically trying to avoid.

Any results of how your HD40 burnishing went ?

My 2000 sq ft floor is poured (YAY !) and I just ordered up HD37 and HD40. So I'm just a few weeks away from doing the same !

Not to hijack Shaggyant but I did get my shop floor burnished. I think I may post a separate thread on the process later.
Everything went fine my floor was power troweled but the finisher in my opinion did not do a great job had some spots that were rough.

I applied the HD40 let it dry overnight about 12 hours applied a 4th coat that next morning let it dry about 3 hours then buffed it. I had a laser temp gauge and it was really difficult to get up to 90 degrees. I had to let the buffer stay in one spot for like a minute or longer. I rented a 1500 rpm machine but my thought was I needed more POWER SCOTTY!! serious seemed like it was just lacking in getting that speed up for friction to heat up the floor. No one in my area had a better unit to rent the next thing was a propane unit that was about 2000rpm.
So make sure you can get a high speed burnisher.

I had exactly the same problem. When I applied the HD37 it was over 90° outside but by last Sunday the temps had dropped to the mid 60's. Looks like we are scheduled to have lows in the 30's this week too. Goodbye summer

I just ran the burnisher until the motor was smoking hot and starting to smell. It did help when I added about five extra pounds on top of the buffer to apply pressure. But you can't press too hard or the motor stops.
