Keeping Slate Floors Clean

Slate Patio Clean – Pressure Washing in Tiverton Devon by JetWash4U

The easiest way to clean slate floors is to be sure they don’t get too dirty in the first place. Coating the floor with a high quality sealer will keep liquids from penetrating the stone and give it a high gloss finish. For the best results, use multiple coats of sealer but allow each coat to dry for at least 30 minutes before applying the next layer. Do not use regular wax to coat a slate floor, as it will dull the stone and make it dangerously slippery. With use, the sealer will eventually wear out, and it should be replaced every few years, with the old coats stripped off before new sealer is applied.It is also easy to keep slate floors clean by using area and throw rugs in the areas most prone to spills and stains, such as near doorways and by kitchen appliances. Avoid wearing shoes on slate floors, as the shoes will drag in dirt, sand, and debris that will stain and scuff the floor. Wipe up any spills immediately to avoid lasting damage, and follow a regular cleaning and maintenance routine to keep your slate floors looking their best.

Getting Rid Of Stains

  • 1Use a soft nylon brush and cleaner to remove stains. Apply a deck cleaner, degreaser, or stain remover to the stain. Rub the stain with a soft nylon brush. Add more pressure if the stain isnt being removed. Rinse the cleaner with water.XResearch source
  • 2Use oxygenated bleach to clean the stones. Oxygenated bleach contains sodium carbonate and mixes with water to create oxygen. Mix the four scoops of oxygenated bleach with warm or hot water until it is fully dissolved in a five gallon bucket. Pour the solvent over dry stone in sections. Let the solution sit for 10 to 12 minutes.XResearch source
  • Scrub the first section with a brush while letting the second section sit on the stone.
  • Rinse the first section before scrubbing the second section.
  • 3Remove dirt and algae with bleach. Bleach can be used to clean dirt, stains, and algae from your stone patio. Mix equal parts bleach with water in a bucket or watering can. Cover the stone with it. Let it sit for around 10 minutes, then brush the stains with a broom. Rinse it well with clean water. You should probably rinse multiple times.XResearch source
  • Use thin, plain bleach for this. Don’t use bleach that has added detergents and other chemicals. These thicker formulas with added ingredients don’t clean as well and may clump on the stone. Just buy basic bleach.
  • Bleach can kill plants if the solution touches it.
  • Rinse the paste with clean water.
  • How To Clean Slate Floors

    Slate floors dont require as much attention as other types of flooring. However, when you do clean, you must do it correctly. There are a few things you should avoid when cleaning this natural stone:

    • Acidic cleaners: Acid can cause a chemical reaction when exposed to slate stone. This will cause the floor to etch and become damaged. So avoid acidic cleaners, even natural ones such as vinegar or lemon .
    • Abrasive cleaners: Strong chemicals can remove the sealer on the floor and grout. This will expose the porous surface to liquids and stains.
    • Oil-based cleaners: These will make the floors slippery and can clog up the textured surface.

    Using The Wrong Treatment For Moss Mold And Mildew

    Stone isnt immune to biological stains and growth of lichen, mildew, mold, and moss. This problem may be especially noticeable in shady areas of the patio that stay damp. Dont use just any product to kill moss, mold, and mildew and remove the stains. Harsh chemicals that are abrasive or acidic can damage the stone. You can easily remove these stains and kill mold by creating a solution of one part water and 1 part bleach. Apply the diluted bleach and scrub the stone with a non-scratch nylon pad or bristle brush to agitate and lift the stain and kill the organisms. After allowing to sit for 15 minutes, rinse away the excess bleach with water.

    Does Slate Scratch Easily

    How To Clean Flagstone Patio In 2021

    The short answer is yes, it can.

    Slate began as a shale a sedimentary rock made of very fine grains of quartz and other minerals. Shales, or mudrocks, are deposited in water in quiet settings, like the bottom of the ocean. Then, the shale is buried and subjected to heat and pressure. It metamorphoses into slate. It takes hundreds of thousands or millions of years to turn shale into slate.

    Slate tiles do get scratched and scratches tend to show more on slates dark colors. To decrease the number of scratches, first try to choose slates that are higher quality harder. Slates are not all created equal.

    Key questions to ask are: is the slate outdoor grade , where is the slate from and does it have low water absorption? Water absorption is important because it can cause the slate to cleave or flake. In freezing climates, water absorbed by the slate freezes and the slate can crack.

    Slates come from all over the world. Natural stone experts say that slate from Vermont and New York is smoother and denser, with low water absorption.

    Slate from Portugal, Wales and the U.K. are high-quality and dense. Chinese and Indian slate is colorful but soft and tend to absorb water. Brazilian slate is colorful, dense and has low water absorption.

    If slate comes from so many places and in lots of grades how do you choose? Before committing big bucks, ask for free samples or buy one or two of the slate tiles you are considering.

    Cleaning Sealed Vs Unsealed Slate Floors: Is There A Difference

    You would essentially clean a sealed slate floor the same way as you would treat an unsealed slate floor. Slate floors and slate tiles dont technically have to be sealed, but once you have gone down this road or the previous owners committed you to this journey, you need to keep that glossy finish up to date.

    A slate floor that has previously been sealed can be cleaned in the same way as a natural slate floor. Be aware that slate is porous in its natural, untreated state and can absorb fluids like red wine and juice.

    Sealing your slate floor decreases its absorption, making it a little more stain-proof. However, if you allow liquids to pool or messes to set, you will still face a nasty discoloration.

    The slates stain-absorbing properties can become a nightmare for you, but using heavy-duty solvents can cause the slate to become brittle and worn down.
