The action of brushing will also break off any small weeks that have just started sprouting preventing them from growing any further.
Brushing up leaves and debris will help to prevent and weed growth or growth from Moss and Lichens
It is pretty much inevitable that at some point a weed will take root and grow. Whether its due to not having time to brush or whether you away for an extended period of time, its going to happen.
When you do get a chance to attend to them make sure that you pull up any weeds that have taken root, taking as much of the root with the weed as possible.
Also, remove any weeds that have taken root in any joints. If you have sand filled joints then in most circumstances the weed will take some of the sand with it. Once all weeds are gone and you have cleaned and swept the area you must then replace the sand in the joint, do not leave it partially filled.
Weedkillers can also be a good solution as, obviously, they will kill any weeds when sprayed. In terms of which weedkillers to use, the best are either contact or systemic killers:
Managing Surface Moss Effectively
Mosses have a very different structure than other plants in your garden or lawn. Because of these differences, common herbicides and home remedies that kill lawn weeds won’t kill moss on sidewalks, decks or patios. In addition, products designed to kill and control lawn moss shouldn’t be used on hard surfaces around your home. Many effective lawn moss killers rely on iron-based substances, which naturally create rustlike surface stains. The best products to kill moss on walks and structures kill moss quickly and eliminate stain concerns.
Effective moss control products kill moss by preventing it from holding moisture. Moss can’t live without water, so it dries out, turns black and dies. The Lilly Miller Moss Out! line offers highly effective, non-staining controls in easy-to-use liquid and dry formulas:
Always read product labels thoroughly, follow all instructions, and make sure your label lists the surface material you want to treat. When treating surfaces close to grass and flower beds or foundation plantings, avoid spraying or sprinkling plants. If that happens, rinse the plants off well.
Proactive annual treatments help keep surfaces free from moss.
How Do I Seal A Concrete Patio
You can protect your patio from stains by sealing it using a concrete sealer. After you have cleaned the patio, use a paint roller to apply the concrete sealer. Start from the middle. Roll the paint roller towards the edges. It is better to work on one small square section at a time, no more than 5 by 5 feet, rather than long narrow strips to ensure that all parts are sealed. Deal with one section at a time. Let it dry. Once dry, you can buff the patio with a non-fluffy piece of cloth to obtain a shiny surface.If you are really set on using a pressure washer for your concrete patio, keep in mind the following points.

This allows the sawdust to absorb the grease or oil, making it loose. Carefully sweep off the sawdust and dispose of it.

You can use leveling grout or sealant as crack filler. Make sure to scrape off any excess sealant. This prevents dirt from moving down the cracks of the concrete driveway when cleaning. Use a garden hose sprayer to spray water on your entire patio.Dissolve two and a half ounces of washing soda in one gallon of hot water. Stir well to make a solution. Subsequently, you can decide to sprinkle dishwashing detergent over your patio to help clean your driveway more effectively. Just make sure that the detergent is powdered for easy solubility.

Why Clean Concrete With Bleach
A simple solution of household bleach poured onto the problem area followed by a hot water rinse can remove dirt, grime, mold, and mildew. In certain instances, using a scrubber or a broom with a bleach solution can release embedded dirt. Since concrete is porous, it will retain both odors and stains. If there is a pungent stench thats permeating from your concrete surfaces, then you will have to seal the concrete to eliminate the odor permanently.
When it comes to oil stains and other stubborn stains, pre-washing the concrete surface with bleach will prepare the area for a further power wash. Bleach can be diluted to the strength that is needed for the particular project you are working on. However, this wont be necessary in most cases.

Eliminating Green Mold From Concrete Steps
Q: The concrete steps at my house are moldy and kind of green on the risers, except where I applied a concrete sealer. I did it badly, so you can see areas that look like drips. How can I safely clean the concrete?
A: When you ask for a way to safely clean concrete, you dont say whether your goal is to protect the concrete, yourself or your plants. Luckily, its possible to do all three.
The least expensive option is to use a little chlorine bleach diluted in water. Bleach solution doesnt damage concrete, but it isnt something you want in your eyes or on your skin or clothing. You could wind up with spots of white or odd colors because bleach affects fabric dye colors unevenly. So before you start working on your steps, put on old clothes, long rubber gloves and goggles, and have a bucket, a sponge and a synthetic scrub brush handy.
When everythings ready, sweep or vacuum the steps to remove loose dirt and debris. Then mix three-fourths to a cup of bleach with one gallon of water, and sponge it onto all the areas where you see the green stains. Keep sponging on more as needed so the concrete stays wet for five to 10 minutes. Scrub with a synthetic brush, then rinse thoroughly. Repeat the process if the concrete is still stained. Rinsing with a hose will dilute whatever cleaning solution is still on the concrete, so it wont harm plants where the water drains.

Drying Out The Affected Surface
It is safe and easier to remove algae when the area is dry. Algae spores thrive and spread in the air when the environment is moist. Removing them in such conditions can make you inhale such pores and that will be dangerous to your health.
To limit the movement of pores, allow sunlight to strike and dry out the area. If there is no sunlight, use fan or heater.
When the surface is completely dry, take a stiff push brush or deck broom to sweep and scrub the affected area on your patio. You may use a plastic scraper if the weeds are stubborn.

Sealing Concrete After Pressure Washing
After cleaning the concrete surface with a pressure washer, lay down a concrete sealant.
We strongly recommend using 2 coats only if necessary. Adding too much sealer can create moisture-related problems, such as efflorescence the salt residue that surfaces from concrete and mortar in wet conditions and color variations.
The first coat will soak into the pores and do the job for providing protection. The second coat is optional but is desired for an elegance effect. If youre going for a shiny gleam from your driveway or patio, use a solvent-based sealer. If you want a more natural look, use a water-based sealer.
Stay off the concrete driveway, patio or stairs for 24 hours. Also, make sure that the weather is dry before even starting this step.
Liquid Laundry Detergent And Household Bleach
To clean mold off concrete, begin by cleaning the concrete surface with a hose, removing as much black mold as possible. If the concrete is located indoors, use a sponge to scrub away the mold. A scraper is also an effective tool for removing the mold from concrete.
Keep in mind that though these methods are effective, physically scrubbing or scraping the mold away will not remove the root, which is embedded inside the porous concrete. If the root is still intact, the mold will simply grow back.
Killing mold beneath the concretes surface requires cleaners that can penetrate the concrete. While bleach is effective and kills mold, its surface tension does not make it ideal for soaking concrete. Laundry detergent is a better option.
Create a cleaning solution by mixing a cup of laundry detergent with a gallon of water. Use a sponge or brush to apply the solution to the floor. The detergent will soak into the concretes pores, killing the black molds roots.
Use a scrub brush to ensure the solution penetrates the concrete and to remove the molds roots. When complete, rinse off the concrete with clean water. If outdoors, use a hose. If inside, use a mop.
Repeat this process if any mold is still present. Dry the concrete with a fan until it is completely dry.
