Cleaning Concrete Slab/Tack Strip Nail Removal - Before Installing Carpet


Pulled old carpet that had a lot of possible mold (urine stains?) and nicotine coming through the old foam pad. Leaving dark splotches on the concrete.

Might bleach do the trick?

Removing tack strip nails has scalloped the slab in some areas (stopped removing for now, so there are many nails left standing with no strips). Don't carpet people normally just go right over these "pullouts"? If the surface has to be patched, which I doubt, I'll hold off on any sealing if concrete -- yet, what type of sealer should be applied over concrete on grade?

Suggestions on treatment?

Pic of removed nails - by pulling.

Angle grinder doesn't seem feasible. Would be a heck of a lot of concrete dust or sharp edges left at top.

I'm guessing this is one reason for the change over to carpet adhesive.

Re: Cleaning Concrete Slab/Tack Strip Nail Removal - Before Installing Carpet


lots of guys use an angle grinder to cut those nails.

floor guys will patch if necessary.

if they want to do it make certain it's not an extra.

use a product called "scoe10x" for the urine.

from experience bleach doesn't work so good.

Hit the nails sideways with a hammer, they will break or come out
Very easy

Bleaching a large area inside will get you chlorine for quite awhile. It isn't recommended.

Why's that?

You mean in the air (lungs) or on the concrete?

Me - just use ammonia straight on spots, cut with water for the main area, then rinse/vacuum up with a wet/dry vac.

Nowadays, there's the enzyme products. Much easier on the human applying them.

Iíve had no problems using bleach to remove surface mold/mildew to prepare surfaces for painting . Because of its caustic nature and poisonous fumes , it should be used sparingly indoors .

Bleach has its drawbacks and limitations. Mainly it can damage many organic materials ( such as wood and natural fabrics ) and will react with iron and other metals and can cause severe corrosion . Good ventilation is a must for indoor use.

Bleach has been my go to for mildew removal, for paint prep , because it is cheap , easy to find , and has immediate results .

I usually dilute bleach with water, 10 parts water to 1 part household bleach , and rinse with clean water . Ventilation is a must , and fumes will quickly dissipate .

I do not know if it will clean your stained concrete , based on my experience, I would test it and see.

There are certainly safer options ,for both the surfaces being treated and the people exposed to the fumes . Still , I have not found more effective options for the quick removal of surface mold and mildew.

Not trying to be contrary, only sharing my experience

Bleach doesn't get rid of mold, it just bleaches it.

Lots of easy to use and effective products out there that work and don't have any bad side effects.

Re: Cleaning Concrete Slab/Tack Strip Nail Removal - Before Installing Carpet


Sodium percarbonate kills mold and mold spores. It's used in oxy type cleaners and deck cleaners. It also used to be part of the Microbium fogging solution, but I think that has been switched to just sodium carbonate.
