Just like removing carpet glue from wood flooring, you’ll need some trusty tools that are key to making this as easy as possible.

Your top priority should be rubber gloves; you don’t want those chemicals on your skin.

To scrape your floor, you can use razor scrapers.

You might decide that a trendy new tool is what you need, but I’ve been using the same scraper for years.

All you have to do is make sure you keep a few extra blades on you, and clean the scraper thoroughly after each use.

You can also try a spackling knife, or a five-in-one tool or razor.

You’ll also need at least a one gallon or 3.8 liter bucket. I recommend bringing a bottle of bleach or ammonia and liquid detergent with you. A heavy-duty scrubber will also come in handy.

If the glue is putting up a fight, you may need a heavy-duty glue remover or mastic remover. Renting a sander or a floor buffing machine may also be a good investment.

2. Removing the Glue

FIrst, let’s look at how to tackle this complete job without resorting to chemicals.

Fill your bucket with boiling water; you’ll use this to soften the glue. Pour the water over the concrete, and leave it for one to two minutes. The softened glue can be scrubbed off with the concrete scrubber.

Water is the cheapest solution here.

Household cleaners/removers

To improve your chances, you can mix 470 ml of ammonia and 240 ml of liquid detergent with one gallon of water. This solution can be used to soften the glue and scrub it off.

You can use bleach instead of ammonia. Don’t combine bleach with ammonia; the resulting solution will produce dangerous fumes.

Bringing on the big guns

If there’s still a bit on your floor, you may need a mastic remover.

Mastic removers are available from most retail outlets. Blue Bear is one of the most popular brands that I’ve used myself.

However, before applying it, it is important to be wary of fumes so it’s a good idea to use a facemask.

You should also ensure that the room you’re working in is well ventilated.

Pay very close attention to the warning labels on the remover’s container.

Use your scraper to remove any remaining glue.

FAQs

Do I need to remove carpet glue before laying vinyl?

Yes, otherwise the floor won’t be smooth and your new vinyl flooring will need fixing as it won’t be level and could have air bubbles.

As for laminate, you may be able to get away with some very thing remnants of the glue left behind. It just depends on the thickness of what’s underneath your new flooring materials and whether it can confirm well to imperfections.

Can I acid stain or paint the concrete after using carpet glue removers?

Yes, as long the glue has been removed from the pores. If glue is trapped in the pores, the stain can’t penetrate it.

If I use mineral spirits or acetone, won’t that “eat away” at the concrete, making it less smooth or adding divots?

That may happen. I recommend that you don’t use harsh chemicals like acetone or mineral spirits on your concrete.

Does vinegar remove glue residue, and if so do I need stronger vinegar, or will what I have in my pantry work?

White vinegar can remove glue residue. It’s food grade and is common in pantries.

White vinegar will not remove all the glue by itself, though, so make sure you scrape as much as you can before applying it.

Also, make sure to use the potent stuff. The bottles you cook with is not quite as strong (acidic) as the more “industrial” type you can get for cleaning purposes.

Removing carpet glue is a detailed and regular part of floor renovations. While it can be tedious when dealing with concrete, it’s straightforward.
