The wet conditions you experienced brought about mold and also mildew expansion on the concrete. This growth usually wake up in damp or shaded locations that don"t get a lot of sun or heat. Concrete, v all the nooks, crannies and also pores, is in reality a great incubator for mold. Wet, humid weather with warm temperatures only boosts the cultivation conditions.

Question:

What"s the best method for remove leaf, jaw cone and other organic stains like urine, blood or sap native concrete?

Answer:

Because organic stains room carbon-based, they tend to be several of the many stubborn stains to eliminate from concrete. They are not permanent, however they can be tough to remove. The essential pigments get embedded in the micro-pores and tiny voids ~ above the surface ar of the concrete. Essential pigments and also oils have the right to be very tough stuff, together anyone who has tried to remove grass stains from garments or clean pine tree tree sap from hands can attest.

One reason you might be having minimal success in removed these types of stains top top concrete is that you room using the wrong cleaners. Necessary stains call for special cleaners targeting essential material. Your common inorganic concrete degreaser, acid or soap will certainly do next to nothing to eliminate these species of stains. The ideal detergent to united state is one with bleaching activity or ammonia. Typically, detergents designed to remove organic stains (blood, food stains, etc.) occupational best; OxiClean is one example. Granular detergents sell an added benefit, due to the fact that they provide added friction when you scrub the surface.

The other element at beat is time. Organic cleaners are consisted of of enzymes and bacteria that actually eat or malfunction the essential material consisting of the stain. This digestive process is slow, and also most essential cleaners require a minimum the 24 hours and also possibly as lengthy as 48 hrs to work before you deserve to reapply them. Essential cleaners generally do not influence the concrete color or damage the surface due to the fact that the enzymes only go ~ organic material, and also concrete is as not natural as you can get. Organic cleaners space readily available at pet stores (dog and also cat urine room the most usual organic stains) as pet odor and stain removers, and also through janitorial supply outlets and also online directly from the manufacturers.

Here space the simple steps come follow:

Apply an organic laundry detergent (as encourage above) to wet concrete. Let that sit because that a couple of minutes.

Scrub vigorously v a stubborn broom or scrub brush.

Rinse the concrete through water till you remove all the soap.

If this procedure doesn"t totally remove the stains, repeat the process. It"s essential to keep in mind that spot cleaning simply those areas where there space stains can an outcome in blotchy concrete. I recommend cleaning the entire concrete slab, or the very least a larger area, come avoid having actually blotchy bleaching spots.

REMOVING FERTILIZER STAINS indigenous CONCRETE

Stains top top a concrete patio result from tree fertilizer.


Question:

I have actually a concrete patio and used a plant food called Bloom Booster once watering the planters ~ above the patio. The next day, i noticed all over water ran the end of the planters, that stained the concrete. I have actually tried scrubbing v a brush attached to a power-scrub setup on my hose. What deserve to I do?

Answer:

Plant food and also fertilizers all contain metals and minerals such as magnesium, iron, copper and also zinc. This list of ingredients reads very much prefer that that concrete acid stain. In essence, you stained her concrete through plant food. The minerals have penetrated the concrete and also reacted v the cement to form a permanent shade change. The reaction minerals are not water-soluble, which means water and scrubbing will not eliminate them. Castle are only soluble in a mild acid solution.

I would begin with a clean white vinegar, diluted 50:50 v water, and also see if that brings the stains out. Girlfriend will require to use the acid equipment on the stain many times, scrub lightly, and then rinse. Check in a little area come ensure friend are getting the results you desire. If the vinegar does no work, you might need to shot a more powerful acid, such together muriatic. Dilute the stronger acid 40:1 v water. Also, be mindful that the acid might etch or adjust the file of the concrete in the areas you clean.

CLEANING CONCRETE COUNTERTOPS, TUBS & SINKS

Question:

What"s the best cleaning method to usage for concrete tubs, sinks and also countertops the receive everyday use?

Answer:

Concrete counter and bathtub surfaces have the right to be really porous uneven they are sealed. If her concrete isn"t sealed, i recommend applying a penetrating sealer. Girlfriend can additionally consider a object membrane sealer, however this will have a sheen and may require much more maintenance. (See Concrete Sealer Types.)

As a general rule, pH-neutral cleaners are best for concrete surfaces. If you have difficult water, usage a scum or difficult water deposit remover. Do not usage aggressive scrubbing pads or abrasive cleansers. Even with cleaning and also sealing, concrete will certainly age and wear like any kind of other surface, but this can actually add character because concrete is a natural material.

INSULATING FOAM STAINS top top CONCRETE


Question:

How carry out we remove residue from spray foam insulation that dropped ~ above concrete indigenous the ceiling above so we can stain the concrete? us scraped turn off the residue, but will the spot withstand stain penetration? What need to we use to clean the area?

Answer:

Most spray foam insulation is made from polyurethane. Whether the insulation is pure polyurethane or a new-generation soy-based foam, it will be sticky and also expand into and also onto anything it touches. As soon as the foam is first sprayed, the a viscous liquid. This liquid gets into the pores of the concrete, and as the expands, that is forced deeper right into the concrete. In essence, you have actually foam-insulted the optimal layer of the concrete, and these locations will resist the stain and show spots as soon as the stain is applied. In some cases, lock may even resist the sealer.

Scraping far the product only clears the foam the is above the concrete surface. The foam the remains below the surface needs to be eliminated by chemical extraction. This entails using a solvent or chemistry cleaner that will certainly dissolve the foam residue, and then extract the liquefied foam indigenous the concrete. A solvent like acetone or xylene or an oil-removing chemical generally works to liquefy the foam. But the extraction process is much more difficult. Acquiring the difficult liquefied foam residue out of the concrete usually calls for dabbing the area through cotton rags multiple time to shot and soak up the residue. Hot water push cleaners also work, yet create a lot of mess.

Foam spots are really stubborn, and even ~ the cleaning and extraction process, some tiny stain or clues is most likely to remain. I typically tell people that the best they deserve to hope for is to minimization the spot therefore the stain shade is only slightly lighter than the neighboring area.

REMOVING CARPET glue OR MASTIC RESIDUE

See the full guide on removing adhesive from concrete.

Question:

I traction carpet indigenous a room and then cleaned the basic concrete floor at least eight times v a trisodium phosphate (TSP) solution. I also used a product from home Depot referred to as Jasco (a no-rinse TSP substitute) come clean the hard-to-remove glue. Ns washed the floor several times through water and let that dry. Next, I applied two coats that Kemiko stain v a garden sprayer adhered to by 3 coats that Chem-Coat sealer, applying it together directed through a lamb"s wool mop and allowing it come dry in between coats. Finally, I used a Chem-Coat security finish. The floor come out beautiful, however after it dried I witnessed a tiny area of the surface ar where it looked favor the sealer or end up coat did not take. It shows up as beaded-up water and does not shine in the area. I would like to correct the problem because it"s noticeable, however I don"t know what come do. Can you offer suggestions?

Answer:

Carpet adhesive is few of the many stubborn stuff the end there. I am impressed that you took so much time come clean that off. Most stain applicators I understand would simply place a microtopping over the concrete and also stain the microtopping vs. Acquisition time to piece off huge areas of adhesive residue.

As much as the sealer beading up, that sounds prefer some remaining glue residue is leading to "fish eyeing." This phenomenon occurs when chemical contamination interferes v the sealer"s capacity to wet out (i.e., penetrate right into the surface). My ide is to apply several coats of complete wax to also out the gloss. If the doesn"t execute the trick, friend may need to go back and strip and reclean that area. This is a messy, time-consuming job and there"s no insurance it will settle the issue. Commonly the applications of floor wax does the trick.

Question:

I used Bean-e-Doo (a soy-based mastic remover) to remove carpet mastic native a concrete floor in my home. The mastic remover has left an oil/grease stain pattern everywhere the floor. What product is finest to remove the stains?

Answer:

A good soap and also water cleaning utilizing a concrete alkaline degreaser soap need to help. Friend should be able to get a concrete degreaser at a hardware store.

MOSS REMOVAL indigenous CONCRETE

Question:

I have concrete pavers and bricks in my backyard. The problem is ns am gaining moss expansion on them. I powerwashed the moss away last year, yet it"s back again this year. Do you recognize what"s bring about this to happen?

Answer:

Bricks and also concrete pavers are an extremely porous, like sponges. They organize moisture, and thus are great little incubators for all kinds of tree life, specifically moss. My guess is girlfriend live in a warm and also humid climate. Friend will require to apply a weed and grass killer to the moss and also then aggressively strength wash every the plant issue away when it dies. Allow the pavers dry, and then seal them with a product designed because that concrete pavers or brick. This should remove or at least substantially reduce the problem. It may take number of coats of sealer to fully fill every the pores in the pavers.

PROTECTING A CONCRETE surface ar FROM pollution BY other TRADES

Question:

What is the best way to prevent stains native construction-related activities on a recently poured slab to plan to it is in an exposed concrete complete (other 보다 hounding the GC to it is in tidy)? I"m worried about contamination by muddy footprints, rainwater/clay runoff, rusting rebar or tin can be ~ left top top the concrete surface, and slurry from sawcuts. What combination of hardening agents, sealers, or protective momentary coverings (polyethylene, burlap, etc.) yields the best protection without including undue expense?

Answer:

Other than urging the basic contractor to store the floor clean, there are two industry-accepted approaches that I have experience with and that occupational well:

Use a cure-and-seal as part of the finishing process. This gives a an excellent cure and also leaves behind an acrylic membrane to protect the floor from common construction traffic and also debris. A cure-and-seal will certainly cost about $0.04 come $0.08 per square foot, depending on the kind of product used and the task size. However, it could limit exactly how you end up the concrete and what form of topcoating you can apply. Be sure to confirm that the cure-and-seal is compatible with everything final end up or coating you plan to use.
