The first thing you need to do is remove all the old paint from your slate board. You can use a sponge or a cloth soaked with rubbing alcohol (or other solvent) to wipe off the old paint. If you are using a cheap slate, it will probably be difficult to get all the paint off without damaging it completely. But if you have used good quality slate, then there shouldn’t be any problem at all!
You may want to try some of the following methods:
Use a brush dipped in rubbing alcohol to scrub off the old paint. Make sure not to rub too hard because you don’t want to damage the surface of your slate.
If you are having trouble getting all the paint off, then you might consider applying a coat of sealer. Sealer is applied over top of existing paint and helps protect it from future wear and tear.
Apply a clear coat over the slate. Clear coats are usually made up of two layers of paint. One layer is applied to the surface and another layer is applied to protect it from scratches and dents. A clear coat will prevent water spots from appearing on your slate board.
How do you know which method works best? Well, let’s take a look at each one of them:
Paint Method – How To Remove Old Paint From Your Slate Board?
Apply a thin layer of clear nail polish remover directly onto the slate. This method works well if you are trying to remove a stain or smudge. However, it’s not recommended for removing old paint since it can cause permanent damage to your slate.
Take a razor blade and scrape away the remaining paint until you reach bare wood underneath. Be careful not to scratch the surface of your slate.
A lot of people use paint to re-paint their chalkboard. This can work well. It all depends on the type of chalkboard you have and how durable it is. Using paint on your chalkboard is a lot cheaper than using a clear-coat or sealer. The problem with using paint is that it can become difficult to write on your board as time goes on.
You don’t want to damage it!
Soap and Water Method – How To Prep Your Slate Board For New Paint?
The best way is to use the same process as listed above, but at the very end, you need to seal the slate with clear nail polish. This protective layer will shield your board from moisture. If your board has bigger areas without paint, then you can try filling them in with a paint pen. This is because chalk will build up around the grooves of your chalkboard, making it hard to wipe away. What tends to happen is that your paint will start to flake off.
Sealer Method – How To Seal A Slate Board
The best solution is to use a clear coat or sealer over top of your chalkboard. The problem with using a sealer is that you need to reapply it every now and then.
Which method is better? From what I can tell, the clear nail polish works the best. You can’t really go wrong with this method if you are trying to protect your chalkboard from moisture.
But how does this all relate to the question at hand? Well, let’s get to that!
The questions was: how do you clean a chalkboard? One of the answers we provided was by using a dry erase marker. If you wait too long to reapply it, then your board may start to get water spots. It also makes the chalk less effective and you’ll end up having to clean the board more often.
The best way is to use a spray sealer, otherwise known as a quick coat. Others prefer to use a brush on sealer and apply multiple coats, but these methods generally take more time and they still don’t achieve the same results as using a spray sealer.
Whatever you do, don’t use a wax-based product. You’ll regret it because they tend to clog up your chalk, making it less effective.
Spray sealers work best because they cover large sections of your chalkboard in one quick motion. This prevents moisture from accumulating anywhere on your chalkboard and keeps your chalk from breaking apart.
Ways To Clean Your Chalkboard
Here are some other cleaning methods that people usually use to clean their chalkboards:
Water and a clean rag – This is the most common method. All you need to do is get a wet rag and wipe away as much dust and chalk as you can. Then, wipe the entire board down again with a dry rag. You can also use Windex or another glass cleaner if you want. It’s your choice!
And there you have it! If you have any other questions about cleaning chalkboards, simply write them below. Thanks for reading and best of luck!
