I live in northeastern New Bailiwick of jersey, and in June nosotros had weeks of rain and humid conditions. Some areas of my concrete driveway adult black spots, and other areas nether pine trees have turned light-green. What is this stuff, and how practise I remove information technology?

Answer:

The wet conditions yous experienced acquired mold and mildew growth on the concrete. This growth usually occurs in damp or shaded areas that don't receive a lot of dominicus or heat. Physical, with all its nooks, crannies and pores, is actually a swell incubator for mold. Wet, boiling weather with warm temperatures only improves the growing atmospheric condition.

REMOVING LEAF, Pino CONE AND OTHER ORGANIC STAINS FROM CONCRETE

Question:

What'due south the best method for removing leafage, pino cone and other organic stains like urine, blood or sap from concrete?

Answer:

Because organic stains are carbon-based, they tend to be some of the about stubborn stains to remove from concrete. They are non permanent, but they can be hard to remove. The organic pigments get embedded in the micro-pores and minor voids on the surface of the concrete. Organic pigments and oils can be very tough stuff, as anyone who has tried to remove grass stains from clothing or clean pine tree sap from hands can attest.

Ane reason yous may be having limited success in removing these types of stains on concrete is that y'all are using the incorrect cleaners. Organic stains crave special cleaners targeting organic material. Your typical inorganic physical degreaser, acid or soap will practice adjacent to aught to remove these types of stains. The best detergent to us is one with bleaching activeness or ammonia. Typically, detergents designed to remove organic stains (blood, nutrient stains, etc.) work best; OxiClean is one instance. Granular detergents offer an added benefit, because they provide boosted friction when you scrub the surface.

The other factor at play is fourth dimension. Organic cleaners are fabricated up of enzymes and leaner that actually eat or suspension down the organic material making up the stain. This digestive process is slow, and most organic cleaners require a minimum of 24 hours and possibly as long equally 48 hours to work before you tin can reapply them. Organic cleaners typically do not affect the physical colour or impairment the surface because the enzymes only become after organic textile, and physical is as inorganic every bit you lot can get. Organic cleaners are readily available at pet stores (dog and cat urine are the most common organic stains) equally pet odor and stain removers, as well every bit through janitorial supply outlets and online directly from the manufacturers.

Here are the bones steps to follow:

Use a pressure washer to remove all solid leaf matter or debris from the concrete.
Apply an organic detergent (every bit recommended to a higher place) to damp concrete. Let it sit down for a few minutes.
Scrub vigorously with a potent broom or scrub brush.
Rinse the concrete with h2o until yous remove all the soap.

If this procedure doesn't completely remove the stains, repeat the process. Information technology's important to note that spot cleaning only those areas where in that location are stains can result in blotchy physical. I recommend cleaning the unabridged physical slab, or least a larger area, to avoid having blotchy bleached spots.

REMOVING FERTILIZER STAINS FROM Concrete

Stains on a concrete patio resulting from institute fertilizer.

Question:

I have a physical patio and used a constitute nutrient chosen Bloom Booster when watering the planters on the patio. The next twenty-four hour period, I noticed everywhere h2o ran out of the planters, it stained the concrete. I accept tried scrubbing with a brush attached to a power-scrub setting on my hose. What can I do?

Respond:

Plant food and fertilizers all comprise metals and minerals such as magnesium, iron, copper and zinc. This list of ingredients reads very much like that of concrete acid stain. In essence, you stained your physical with constitute food. The minerals have penetrated the concrete and reacted with the cement to form a permanent color change. The reacted minerals are non water-soluble, which means water and scrubbing volition not remove them. They are just soluble in a mild acid solution.

I would start with a clear white vinegar, diluted 50:50 with water, and see if that brings the stains out. You will need to apply the acid solution on the stain multiple times, scrub lightly, and then rinse. Exam in a small-scale area to ensure you are getting the results yous desire. If the vinegar does not work, you may demand to try a stronger acid, such as muriatic. Dilute the stronger acid xl:1 with water. Likewise, be aware that the acrid may etch or change the profile of the concrete in the areas you clean.

CLEANING Physical COUNTERTOPS, TUBS & SINKS

Question:

What's the best cleaning method to use for physical tubs, sinks and countertops that receive daily employ?

Reply:

Physical counter and tub surfaces can exist very porous unless they are sealed. If your concrete isn't sealed, I recommend applying a penetrating sealer. You can likewise consider a topical membrane sealer, simply this will have a sheen and may crave more than maintenance. (See Concrete Sealer Types.)

Equally a general rule, pH-neutral cleaners are all-time for concrete surfaces. If you take hard water, use a scum or hard water deposit remover. Do not use aggressive scrubbing pads or annoying cleansers. Fifty-fifty with cleaning and sealing, concrete will historic period and vesture like whatsoever other surface, but this can really add character since concrete is a natural material.

INSULATING FOAM STAINS ON Concrete

Chris Sullivan Site Chris Sullivan

Areas where spray foam insulation dropped on concrete will resist acid stains and dyes.

Question:

How do nosotros remove rest from spray foam insulation that dropped on concrete from the ceiling above and so we can stain the physical? We scraped off the residual, but will that spot resist stain penetration? What should nosotros use to clean that area?

Answer:

Virtually spray cream insulation is fabricated from polyurethane. Whether the insulation is pure polyurethane or a new-generation soy-based foam, it will be glutinous and expand into and onto anything it touches. When the cream is first sprayed, information technology's a viscous liquid. This liquid gets into the pores of the concrete, and as it expands, it is forced deeper into the concrete. In essence, you have foam-insulted the pinnacle layer of the concrete, and these areas will resist the stain and show spots when the stain is applied. In some cases, they may even resist the sealer.

Scraping away the material only removes the foam that is above the concrete surface. The foam that remains below the surface needs to be removed by chemic extraction. This involves using a solvent or chemical cleaner that will dissolve the foam residual, and then extracting the liquefied foam from the physical. A solvent like acetone or xylene or an oil-removing chemical commonly works to liquefy the foam. Only the extraction process is more difficult. Getting the viscid liquefied foam residual out of the concrete unremarkably requires dabbing the area with cotton rags multiple times to endeavour and soak up the residue. Hot h2o pressure cleaners also piece of work, but create a lot of mess.

Foam spots are very stubborn, and fifty-fifty after the cleaning and extraction procedure, some pocket-sized stain or spot is likely to remain. I typically tell people that the all-time they tin can hope for is to minimize the spot so the stain color is only slightly lighter than the surrounding surface area.

REMOVING CARPET Mucilage OR MASTIC RESIDUE

See the total guide on removing gum from physical.

Question:

I pulled carpet from a room so cleaned the underlying concrete floor at least eight times with a trisodium phosphate (TSP) solution. I also used a production from Home Depot called Jasco (a no-rinse TSP substitute) to clean the difficult-to-remove glue. I washed the floor several times with h2o and let it dry out. Next, I applied ii coats of Kemiko stain with a garden sprayer followed past three coats of Chem-Glaze sealer, applying information technology as directed with a lamb's wool mop and allowing it to dry out betwixt coats. Finally, I applied a Chem-Coat protective terminate. The flooring came out cute, only after it dried I saw a small surface area of the surface where it looked like the sealer or end coat did non take. It appears equally beaded-up h2o and does not shine in that expanse. I would similar to correct the problem because information technology'southward noticeable, but I don't know what to do. Can you lot offer suggestions?

Answer:

Carpet gum is some of the about stubborn stuff out at that place. I am impressed that you took so much time to clean it off. Almost stain applicators I know would only place a microtopping over the concrete and stain the microtopping vs. taking time to strip off big areas of glue residue.

Equally far as the sealer beading up, information technology sounds like some remaining glue residue is causing "fish eyeing." This phenomenon occurs when chemical contamination interferes with the sealer's ability to wet out (i.e., penetrate into the surface). My suggestion is to apply several coats of terminate wax to fifty-fifty out the gloss. If that doesn't do the play tricks, y'all may take to go back and strip and reclean that area. This is a messy, time-consuming job and in that location's no guarantee it will solve the outcome. Usually the application of floor wax does the play a joke on.

Question:

I used Edible bean-east-Doo (a soy-based mastic remover) to remove carpet mastic from a concrete flooring in my home. The mastic remover has left an oil/grease stain pattern all over the floor. What product is best to remove the stains?

Answer:

A good lather and h2o cleaning using a concrete alkaline degreaser soap should help. You should exist able to become a concrete degreaser at a hardware store.

MOSS REMOVAL FROM Concrete

Question:

I take concrete pavers and bricks in my backyard. The trouble is I am getting moss growth on them. I powerwashed the moss away last twelvemonth, but information technology'due south back once again this year. Do you know what's causing this to happen?

Respond:

Bricks and concrete pavers are very porous, like sponges. They hold wet, and thus are bully little incubators for all kinds of establish life, especially moss. My guess is you lot alive in a warm and humid climate. You will need to utilize a weed and grass killer to the moss and and so aggressively power wash all the establish matter away once it dies. Let the pavers dry, and so seal them with a product designed for concrete pavers or brick. This should eliminate or at to the lowest degree profoundly reduce the trouble. Information technology may take several coats of sealer to completely fill all the pores in the pavers.

PROTECTING A Physical SURFACE FROM Contagion BY OTHER TRADES

Question:

What is the best way to forbid stains from construction-related activities on a newly poured slab intended to be an exposed concrete finish (other than hounding the GC to be tidy)? I'g worried about contamination by muddy footprints, rainwater/clay runoff, rusting rebar or can cans left on the concrete surface, and slurry from sawcuts. What combination of hardening agents, sealers, or protective temporary coverings (polyethylene, burlap, etc.) yields the all-time protection without adding undue expense?

Reply:

Other than urging the full general contractor to proceed the floor clean, in that location are two industry-accepted methods that I accept experience with and that work well:

Utilise a cure-and-seal as part of the finishing process. This provides a skillful cure and leaves behind an acrylic membrane to protect the floor from typical construction traffic and droppings. A cure-and-seal volition cost most $0.04 to $0.08 per square pes, depending on the type of production used and the job size. Still, it could limit how you cease the concrete and what blazon of topcoating you can apply. Exist sure to confirm that the cure-and-seal is compatible with any concluding finish or coating you plan to use.
Use a physical barrier like Builder Board from Surface Shields. This is a groovy, relatively depression price method to really keep the floor make clean and protected. This volition cost more the first option, but is far superior in protection. These boards besides come in water-resistant versions if yous are concerned about water exposure or chemical contamination.
