You’d prefer to utilize chalk paint on your venture, yet it’ll be outside or close to water. Is chalk paint appropriate for wet furnishings? 

Chalk paint is a typical choice for giving furnishings and home stylistic theme a natural, collectible, or ratty stylish look due to its matte, powdery appearance. 

Chalk paint is ideal for the individuals who need to add character and antique appeal to their home since it can without much of a stretch be troubled. 

Chalk Paint is a simple to-utilize, fast drying, and trustworthy beautiful furniture paint. Chalk paint is waterproof. Yet, on the off chance that the surface is presented to water, it needs an enamel sealer. 

It isn’t waterproof and can not be seen on wet surfaces. 

Let’s look at chalk paint in more detail.

What really is chalk paint?

Even if you recognize the appearance of chalk paint, you might not know what it is. This advanced paint, which is not to be confused with chalkboard paint, which produces a surface that can be written on with chalk, gives surfaces a chalky look and feel. 

After the chalk paint has dried, many DIYers use waxes and finishes to seal the surface, produce patina, and give it an antique feel. 

Chalk paint will work with a range of home decor types, from modern to bohemian to farmhouse, depending on whether you paint an object a solid color or add a vintage finish.

In addition to its matte finish, chalk paint differs from traditional paint in a number of ways. One of the advantages is that it doesn’t take much preparation; it can be applied directly on most clean, dry surfaces, even though they’ve already been painted. 

As a result, DIYers prefer to use chalk paint on antique parts with cracks or a lot of specifics, since the paint applies smoothly, even over layers of paint. 

Because of its consistency, chalk paint is less likely to spill than regular paint. 

You should wash your brushes with soap and water instead of mineral spirits because chalk paint is water-based.

What are the various kinds of chalk paint?

Paints with a chalky finish that can be applied with a brush or a spray can are available. Because of its self-leveling properties, chalk paint is usually simple to use in any type.

  1. Spray Chalk Paint:

Spray chalk paint dries much faster than regular chalk paint, allowing you to complete your painting project sooner. 

Spray painting helps the paint to enter crevices and hard-to-reach areas, which is ideal if you’re painting a piece with intricate carving or spindles. 

Spray chalk paint has a smooth, streak-free finish, but it doesn’t penetrate the surface as well as normal chalk paint. It also takes more layers to cover your project than standard chalk paint, potentially increasing the cost. 

Finally, bear in mind that cleaning oil-based chalk paints is more difficult than cleaning water-based chalk paints.

  1. Acrylic Chalk Paint:

A 100 percent acrylic base is used in most industrial chalk paints. This is a water-based paint with an acrylic polymer binder that keeps the pigment in place. 

It has a number of benefits over other spray forms due to its formulation. Chalk paint with an acrylic base dries easily, usually in 20 to 30 minutes. 

The paint can be quickly wiped up with water when it’s wet, but if it’s dried, the colour is permanent. 

Acrylic-based chalk paints stick to almost every wall, making them useful for a wide range of DIY ventures. 

Another advantage of acrylic-based chalk paint is that it has no residue or fumes. This paint is safe to use indoors and clean up is easy.

Chalk Paint Do’s & Don’ts

It’s a breeze to use Chalk Paint outside. You’ll need to know these things if you want your Chalk Paint designs to last for years.

✔️ Chalk Paint can be used outside.❌ Sanding should be avoided at all costs. There’s no need to prep or prime the outdoor furniture as there is with Chalk Paint indoors.
✔️ Removing old peeling paint or rust is a must. You can paint over these, but if you don’t get rid of them, they’ll begin to peel under your Chalk Paint and finally flake off, taking your beautiful new paint job with them. Since rust can show through, it’s best to attack it head on.❌ The vertical surfaces, such as shed walls, fences, and brickwork, should not be lacquered since they are porous and vertical faced. This means they’re less vulnerable to the main causes of outdoor destruction, such as UV rays and standing water, which are two of garden furniture’s worst enemies.
✔️ Wipe away any cobwebs or ashes, open your Chalk Paint box, and get right to work.❌ Chalk Paint Wax can never be used outside.
✔️ Knowing when to lacquer and when to leave is important. Your garden furniture’s best defense against UV rays, fading paint color, and peeling paint caused by water loss is Chalk Paint Lacquer.
✔️ Lacquer is something you can do. Garden furniture should be covered with Chalk Paint whether it will be touched often, sat on, or has a horizontal surface that will absorb water or fade under direct sunlight. Lacquer to prevent color from transferring, peeling, or fading.
✔️ Two coats of lacquer are recommended. Apply two or three thin coats of Chalk Paint Lacquer to ensure that the whole finished item is thoroughly sealed from water infiltration. It’s worth noting that the curing process takes 14 days for optimum security.
✔️ And sure you look up the weather forecast. If any Chalk Paint or Lacquer has not dried well until being exposed to sunlight, rain may wash it away and compromise it.
✔️ Make use of bright colors. It’s better to be bold outside.

What are the advantages of using chalk paint?

Chalk paint is common with DIYers because it has the following advantages:

  • It doesn’t need to be primed or sanded before use.
  • It is easy to clean brushes and equipment with water and soap.
  • Because of its dense consistency, it drips less.
  • It does not require furniture to be stripped before painting. 
  • It can be used on almost every kind of surface, including wood, aluminum, concrete, and stone.

Is chalk paint waterproof?

Chalk paint’s popularity stems from its undeniable versatility. It can be used to produce a distressed, shabby chic look or to breathe new life into an antique piece of furniture. 

Wood and laminated furniture, concrete, acrylic, cladding, mortar, stone, and glass will all be painted. It’s one of the simplest paints to use, and it’s low in volatile organic compounds (VOCs), making it safer for the environment than traditional paints with high VOCs.

Outdoor chalk paint is water resistant, and some manufacturers also have additives that help prevent mould growth and regrowth, which is especially useful if you live in a humid environment.

You can paint everything with it, from plant pots and sheds to back doors and plastic garden furniture, thanks to its flexibility. Chalk paint adheres well to almost every board, so you won’t need to use a primer. Before you begin painting, make sure the surface is smooth, dried, and clean.

If you’re considering painting metal furniture, you might have found that the new paint has begun to flake away. You can first use a steel brush to clean any loose, flaking paint before applying a fresh coat. 

Check for any wood that is falling away from the surface while you’re painting an old piece of wooden furniture. If you’ve discovered a lot of splinters, the wood would need to be primed first.

You should also consider the kind of surface you’ll be painting on. If you’re painting a porch or balcony, for example, the paint can make the surface slippery. 

Be sure the color you pick won’t have a significant impact on the surface’s grip. When the surface is cleaned, we recommend gently scuffing it with sandpaper.

The heat is the final consideration. Excessive heat or extended exposure to the sun may cause the chalk paint to fade. Every other year, give your furniture a brief refresher. 

You may also use a sealant to protect the chalk paint from sun damage.

What is the best way to use chalk paint for outdoor furniture?

You can also use chalk paint to refinish your old outdoor furniture because it is so versatile. 

Chalk paint is a brilliant way to refresh your furniture without having to buy new furniture, whether you’re either looking for a change or you came across some antique furniture in a charity shop. 

The best thing about chalk paint is that there isn’t a lot of extra time or a steep learning curve. You should jump straight in.

Step 1: Choose a paintable object and collect supplies

Pick a color for the paint. Since the remaining natural wood has a lovely reddish hue, most customers go for a darker blue paint color, as the red will show through in spots when distressed later, creating a pleasant comparison. Also collect the painting essentials such as

  • A can of wax and a wax cleaner
  • Sandpaper 
  • A clear chip brush
  • Shop towels or other lint-free cloth or mat 
  • A strip of aluminum foil for protecting your wet paint brush if you need to take a break and don’t want it to dry out 

Step 2: The furniture should be cleaned

You don’t have to scrub your furniture of everything, like old paint or finishes, so you can make sure it’s clean and dry. 

The safest choice is to use soapy water. It should not be cleaned with furniture wax. Many furniture polishes contain wax, which does not blend well with chalk paint.

Step 3: Place a drop cloth or old sheet below the furniture

If you’re a sloppy painter, lay down a drop cloth or an old sheet underneath your item. 

Don’t think about it if you’re neat. If you have chalk paint on your carpet or floor, it’s easy to clean with a little dish soap or laundry detergent, spray, and elbow grease.

Step 4: Paint the furniture with the chip brush

This is where chalk paint’s true beauty lies. You don’t have to make sure that all of the brush strokes are running in the same direction; you don’t have to make sure that the coverage is even; and you certainly don’t have to paint every nook and cranny if you don’t want to. 

Since the current finish on the table top has worn away, two coats are needed. It would require more color to coat the unfinished wood.

Step 5: To get the desired distressed look, lightly sand the surface.

Be sure you’re using sandpaper with a fine grit. The finer the grooves in the furniture, the rougher the sandpaper. 

You’re not attempting to sand through to the wood, but rather to the finish under the paint coat. It’s all up to you when and how much color you sand off. 

Don’t worry if you go nuts and sand down too far. You can still paint another coat of color if necessary.

Step 6: Sanding dust should be wiped away

Wet one of the shop towels and use it to wipe off the furniture. You’re attempting to clean up the dust generated by the sandpaper.

Step 7: If you’re going to use chalk paint outside, make sure to seal it.

Most chalk paints don’t need to be sealed before being used outside, but if you want to be secure, use a multi-purpose sealant that will shield your painted object from moisture, heat, and UV rays. 

It works by expanding and contracting in response to changes in the surface temperature, particularly during hot and cold spells.

A smooth bristled brush is best for applying the sealant. Apply generously to the object to be protected and allowed to dry.  

It would need to dry for at least 24 hours, so double-check the overnight temperatures to make sure there isn’t any risk of rain.


Don’t be concerned if you like the look of chalk paint but are concerned that it won’t hold up to water. 

If the surface may be exposed to standing water, such as a bench, tabletop, or brick patio, a lacquer seal may be required. If you want to paint a wall, chalk paint will work perfectly if you give it enough time to cure.
