Best way to keep moss from growing on concrete?

[nervewrecker]

Have a few threads I saw about how to remove it and finding info online on how to remove moss / fungi / algae etc but nothing to keep it from growing.
As of late it has become a nuisance and im looking for a solution. Is there any sealer of some sort that will retard the growth or keep it from growing?

thanks.

muriatic acid is epic for removing existing moss, talk to rory pholourie man he may advise better.

Dunno if that acid is the same thing a slye, but I just sprinkle lye diluted in water and it comes out clean.

that not toxic?

[Chimera]

Ent they does use chlorine powder as well

[cueball1990]

Best i can suggest is painting the surface with a waterproofing paint and put a moss deterrent the paint. It might work

I not sure of that acid is the same as lye but as mg man said, that's a concern of mine.

There are paints that are moss resistant? Please tell me more about these and where I can get it. Don't mind using it especially if it's clear.

I know about the chlorine powder as well but can't find it around my home town. Is it safe to use in a semi enclosed area?

Thanks for the replies so far.

keeping the moisture from settling on it or around it. tends to happen where greenery such as plants are around. latex paint might work.

i use chlorine powder all around my yard, it keeps it clean but you have to follow up every couple weeks once you have water settling .

Where do you get this to buy ?

[MonsterPower]

Most hardware has the chlorine powder

[j.o.e]

Or pool supply shops. They have the better quality one.

[MG Man]

how do you apply the chlorine powder? Is it mixed with water at some specific ratio, or just sprinkled?

[j.o.e]

Late evening or night soak down area ... Sprinkle powder , dampen area of necessary to help powder break down. Leave overnight. Wash off after 24hrs or so. Can dampen concrete following day to give it more time to work. That's my method.
The one sold in pool shops are bigger more crystalline particles rather than the powdery stuff at hardwares ..... So it breaks down over night and seems more concentrated.

Clean the moss with any commercially available cleaner, I use household bleach, and then seal the concrete surface. You should contact SCL (Trinidad) Limited (675-5555) to find out what concrete sealants they have which will prevent the growth of moss and will still have good traction at the surface.

Mix household bleach and water in a 1:3 ratio and spray on with a cheap 2 gall spraycan.
After initial treatment, it may require reapplication every couple months in the rainy season.

Thanks for all of the replies so far and thanks for the info Rory.

Sherwin Williams has a clear concrete sealer. Also they have concrete stains... both would keep moss off.

Unfortunately, I have come to the conclusion that there is no product designed to stop moss and algae growth on concrete surfaces.
The above having been said there are numerous methods to control and clean build-ups.
Everything used only works for a time, so property owners with concrete paved surfaces are doomed to continuous maintenance activities.
BTW, be very careful with the chlorine granules solution since they release free chlorine to atmosphere and can quietly create problems for individuals with respiratory challenges.

I have a pal working Sherwin Williams, will ask him about this stuff.

in future try and have proper grade and make sure the handmixed concrete
is properly mixed and not like soup or it becomes a weak and porous mix like
what you see on on many local citcy corp constructed sidewalks

[ruffneck_12]

rip out the concrete and put grass pavers

boom shiggy

A concrete sealer that is solvent based will work. Eg superseal b26.
But the conditions are to be ideal for it to work effectively. Eg proper slope, smooth finish(power float),moisture barrier under slab, levels of shade / sunlight the area gets all contribute to the moss build up.
Biocidal solution is what the paint shop sells but I don't see much of a difference of the result.
According to the conditions above there are different types of moss that will grow.eg it the front of my house that gets sun only from 3-6 pm has a brown colored moss that is easily cleans with a pressure washed. On the side of the house that gets sun for more hours there is a black moss and is real pain to clean. Twice as much effort to clean that the brown moss.

hey nerve,

i have a large concrete yard. moss is an ongoing problem for me.

i buy chlorine powder from ramlagan hardware in couva for $10 a pound.
sprinkle it on wet yard and leave overnight.

It cuts most of the moss, then u can spray it off with a pressure washer or hose.

Bleach also works if you can't find chlorine powder.

This is just an edge of the concrete under where the roof falls. rain blows in when it falls, about 2.5 - 3 feet in width. Have green black and brown.
Concrete is in fact porous and rough.

tile it or paint it! there are paint products for concrete but u need to look at total cost as opposed to tiling say.

lye is caustic sodium hydroxide. muriatic acid can't be mixed with it, there will be a violent reaction. the lye or chlorine granule or bleach is best to cut moss for a time.

Plant grass

keep the water off the concrete, extend yuh roof or install an awning or buy the artificial turf for $13/sq ft!
