How to Clean Concrete Before Staining It

Stained concrete floors are a popular choice of commercial flooring among business owners. For those who are considering staining their concrete floors themselves, you need to know it is important that the concrete be as clean as possible before you start the staining process. Here is some information that will help you get the task done right.

Why it is Crucial to Clean Concrete before Staining

Unlike paint and other concrete coatings that help conceal flaws, acid stains are not forgiving. If the surface is not correctly cleaned, it can be difficult, if not impossible, to obtain a proper finish. Chemical stains must be able to penetrate into the concrete in order to create the necessary chemical reaction within the lime content contained within. Spots from grease, oil, or curing renderings will prevent the penetration necessary for the color to take.

Choosing the Right Product to Clean Your Concrete Floors

There are many products available to clean concrete, but not all concrete cleaners work on every type of stain. It's not always easy to determine what caused a concrete stain just by looking at it. It's important to read the labels on each of the concrete cleaners you are considering. The label will give you valuable information you can use to decide which cleaner is the best for your concrete floor.

Facts you need to know before selecting your cleaner include:

Is this product safe for indoor use?
What substances does this cleaner remove?
Is it an environmentally safe product?
Does it give off fumes or noxious odors?
Is this product compatible with the concrete stain you have chosen?
How do you apply the product?

There are safe, environmentally friendly products available for cleaning concrete. You should always use caution, however, and be sure and read and heed any safety measures recommended by the manufacturer.

Concrete Cleaning Procedures

Start by sweeping and thoroughly scrubbing your concrete floor with trisodioum phosphate (TSP). Use a rotary scrubber with a pad specifically designed for aggressively scrubbing concrete.

Mastic and caulking compound can be particularly difficult to remove. There are two methods you can try. You can try using a nonflammable chemical stripper, available from hardware or paint stores or you may need to create a paste to apply where necessary.

First, scrape off as much of the unwanted glue or caulking as possible using a floor scraper or putty knife. Next, blend an inert fine powder like hydrated lime or fly ash with denatured alcohol to form a smooth paste. Apply where necessary and let dry. Once the paste is dry, the mastic or glue can usually be removed with a stiff brush.

After using your cleaning compounds, scrub the floor again with TSP and then rinse thoroughly with clean water.

Finally, you'll want to use a wet vac to dry the floor.

It is hard work to properly clean a concrete floor and prepare it for staining, but this step is crucial. A clean surface is the best foundation for your stained concrete floors.

Asphalt Installation - Understand the Process Before You Choose a Paving Company

If you're thinking about getting asphalt installed, either as a driveway or something else, knowing how it's installed is important. Not only will it help you know what to expect during the installation, but you will understand where your hard earned money is going. Here is some information on asphalt installation to help you understand the process before you choose a paving company.

The Stone Layer

Typically, asphalt installation begins with the company putting down a layer of stone or gravel. Many contractors use crushed gravel as it is the least expensive base to use for the asphalt. If you want the best sort of underlay for your asphalt, you can request a larger stone - however, be prepared as it may cost you more. Once the stone layer has been put in, the contractor will move on to the pouring the asphalt.

Pouring the Asphalt

Generally, after the stone has been selected and placed where it is needed, the contractors will pour the asphalt. You may notice that the gravel extends a few inches past where the asphalt is poured. This is good - if the asphalt made it to the sides of the gravel to the dirt or grass, it can easily break off at the sides as there is nothing supporting it. This will make your driveway look terrible!

Leveling

After the asphalt is poured, you will notice your contractor using a machine to straighten or level the surface of the driveway. This is to make sure everything is perfectly level and that there are no bumps or areas that are higher or lower than the rest of the asphalt. When this is finished, your asphalt only needs to cool and set up and you will have a brand new driveway. The time it takes to finish your driveway depends on how large it is and many other variables. Your contractor will discuss this with you before the job is started.
