1. The Epoxy Paint Method
Using epoxy paint that you can find it here, is a great way you can give your marble window sills the kind of facelift it deserves. This is particularly great for cultured marble window sills.
The downside to using the epoxy paint method on your marble is that epoxy paints have very strong fumes and smells.
So you would want to make your room as well-ventilated as possible. You can leave all other windows and doors open. You would also want to make sure you do this when your kids are out for school or simply send them to the park along with any pet you may have.
With all other windows opened and doors left open and a good ventilator mask, your should be able to work safely while making your window sills the best on the block.
Things Needed:
- Marble cleaner which can be bought at Amazon
- Cleaning brush or a Vacuum Cleaner
- Rubber Gloves
- Paint Brush or a High-Density Foam
- Protective Glasses for Eyes
- Epoxy Paint, you can find the best one at Amzon.
Procedure:
Step 1:
Dust off and clean any accumulated dirt, dust, or debris from the surface of the marble window sills with a cleaning brush or vacuum cleaner and the regular cleaning product or solution you often use for your marbles.
You would also want to remove anything you might have placed on your marble window sills such as flowers or plants before doing carrying out this step.
You would want to clean your marble window sills as thoroughly as possible. You can absolutely OCD this as much as you can :D.
Step 2:
After thoroughly cleaning your marble surface, you would want to leave the marble surface to dry especially if it got wet in the process of cleaning either from using a damp cloth or a wet marble cleaner.
Step 3:
One more prepping to do and you will be all set up for the painting activity. Now tape off all other parts around the window sills so that it doesn’t get stained with paint.
You would want your marble window sills to be as professional-looking as possible.
Step 4:
Now it’s time to gear up! put on your ventilator mask, protective glasses, and a pair of gloves.
Step 5:
Now with the help of the recommended painting brush for the epoxy paint start painting your marble window sills.
You can use a paint roller if the paint brush is giving you a tough time.
You would want to apply multiple even layers of epoxy paint on the marble and make sure to allow each application to dry for about an hour.
You wouldn’t want to wait over an hour as doing so will mean you will need to wait for about a week for the epoxy paint applied to cure completely before you can apply additional layers of paint.
So aim for the 1-hour mark. Add as many coats of paint to your marble window sills as much as possible until you’re satisfied with the look.
Step 6:
Leave the painted marble window sills to completely cure for 4-5 days. The longer the better! Voila!
2. High Gloss Oil-Based Paint Method
Here’s a detailed step-by-step guide on how to paint marble window sills using the High Gloss Oil-Based Paint Method. Let’s start with the items you will need to execute this method for the best results.
Things Needed:
- Soft Cleaning Brush
- 36 Grit Sandpaper
- Nose Mask
- Gloves
- Tack Cloth
- Masking Tape
- Oil Based Primer
- High Gloss Oil-Based Paint (Alternatively you can use latex paint)
- Paint Brush or Paint Roller
Procedure:
Step 1:
Start by brushing off any sort of dirt, dust, or debris accumulated around the marble window sills.
It’s pretty obvious your marble window sills will accumulate a lot of dust and dirt since it’s stationed outside and exposed to the elements of the weather.
Doing this will help to ensure that everything remains clear and that you have a good idea of the surface you’re working on.
Step 2:
Now sand the surface of your marble window using 36 grit sandpaper. This will help remove the gloss, finish, or any dirt or grease buildup on the surface of your marble.
It’s also a great way to give your marble tooth to adhere to any paint you may use. This is probably the most challenging part of this DIY as you will have to ensure you do not leave behind any glossy spots amidst the fine dust from sanding the marble.
It’s important to get rid of the gloss on your marble window sills as much as possible as any glossy shine left behind can prevent your paint from adhering to the marble for a nice beautiful look.
The way you would know you have completed this step is when the entire surface of the marble window sills look dull, matte, and slightly rough.
Step 3:
After you have successfully sanded the entire area of the marble, use a damp tack cloth to remove all of the loose dust particles from the surface of the marble.
It should look dull and feel slightly rough when you’re done.
Step 4:
Allow the marble window sills to dry thoroughly.
Step 5:
If necessary, tape off any portions around the marble window sills so that you don’t get any primer or paint on parts of the window you do not want stained.
If you’re applying this method to tabletops or countertops, you would want to make sure to use a drop cloth on your floors and other surfaces you wouldn’t want stained.
Step 6:
Now prime the surface of the marble you have just sanded using an oil-based primer and a paint brush or roller.
Priming is a very important step in this process. It will serve as a base for your painting. Priming your marble window sills before painting will also help to make your paint application a lot more durable, save you paint, and a lot of time.
This is because oil-based primers help to make paints last long on marbles and help to make it highly resistant to any weather condition.
If you prime your marble surface properly after sanding, you will avoid having to re-apply several layers of paint on your marble window sills to get it even.
Step 7:
Leave the primed marble surface to completely dry for about 8 hours.
Step 8:
Now it’s time for the fun part; Painting. Apply at least 2 thin even coats of your favorite paint color on your marble window sills and make sure to allow each coat to dry for not less than 16 hours.
Depending on the kind of look you’re aiming to get, you can add more layers of paint.
It’s important to mention that there’s no need to rush this process. If done in a rush, the result may be a patchy or bubbled finish which may look very unprofessional.
I personally like using high gloss oil-based pains as that is a lot more durable and highly resistant to the weather elements.
Step 9:
Leave the painted marble window sills to cure for about a week. While the paint cures on the surface of the marble you need to ensure you do not touch or place anything on it as this can cause the paint to come out.
Your marble window sills should be good as new and should be able to withstand any weather condition thrown at it for many years to come.
This method, however, is not only limited to marble window sills. You can also use this method to paint over your marble countertops and tabletops.
