DIY Concrete Coasters Tutorial

DIY concrete coasters are a fun, easy, and functional DIY. If you’re wondering how to make your own concrete coasters, I’ll walk you through the whole process!

To get started, gather the necessary supplies:

  • Concrete mix
  • 2 plastic cups or bowls for mixing
  • Ruler or tape measure
  • Wax paper or parchment paper
  • Paintbrush
  • Acrylic paint of various colors (optional)
  • Glue gun

DIY Concrete Coasters Calculator

Used formula to calculate the amount of concrete needed for a Concrete Coasters

To calculate the amount of concrete needed for a DIY Concrete Coasters project, you will need to know the volume of the coaster shape. The formula to calculate the volume of a cylinder is:

V = π * r^2 * h

where V is the volume, π is pi (approximately 3.14), r is the radius of the base of the coaster, and h is the height of the coaster.

For example, let’s say you want to make a concrete coaster that is 0.5 inches tall and has a base radius of 4 inches. Using the formula above, we can calculate the volume as follows:

V = 3.14 * (4 inches)^2 * 0.5 inches V = 3.14 * 16 inches^2 * 0.5 inches V = 3.14 * 8 inches^3 V = 25.12 inches^3

So you need 25.12 inches^3 of concrete to make the coaster. However, to convert it to cubic yards, you will have to divide by 1728 and then by 3.

Homemade Concrete MixHighSlowHighLowRequires sourcing individual ingredients

There are several types of concrete that you can use to make your coasters. The most common are quick-set concrete and traditional concrete. Quick-set concrete is a pre-mixed blend that hardens faster than traditional concrete, making it a good choice for projects that need to be completed in a short amount of time. However, it may not be as strong or durable as traditional concrete.

Traditional concrete, on the other hand, is made by mixing cement, water, and aggregate (such as sand and gravel) together. This type of concrete takes longer to set, but it is stronger and more durable. You can buy bags of premixed concrete at most home improvement stores, or you can make your own by mixing cement, sand, and gravel in the desired ratio.

Another option is ready-mix concrete, which is a premixed blend of cement, water, and aggregate that can be purchased at a concrete plant or home improvement store. This type of concrete is convenient, but it may not be as customizable as traditional concrete.

Molds and Forms

Concrete Coasters

Molds and forms are an essential part of the concrete coaster-making process, as they give the coasters their shape and size. There are many different types of molds and forms available, including silicone, plastic, and wood.

Silicone molds are popular because they are flexible and easy to use. Simply pour the concrete mixture into the mold, vibrate it to remove any air bubbles, and then let it set. When the concrete has hardened, you can easily remove the coaster by gently flexing the silicone mold.

Plastic molds are another option, but they may not be as flexible as silicone molds. They also tend to be more prone to cracking, so they may not be as durable.

Wooden molds are another option, but they require more work to make. You'll need to cut the wood into the desired shape and size, and then seal the edges with a release agent to prevent the concrete from sticking. Wooden molds are not as flexible as silicone or plastic molds, so you'll need to be careful when removing the coasters.

Step 1: Prep

Now that you have all of the materials needed, it’s time to start making your coasters. Begin by measuring and cutting out a piece of wax paper or parchment paper that is slightly larger than the plastic cups you are using for the coasters. Place this piece of paper on a flat surface and set the two plastic cups in the center.

Step 2: Mix your concrete

Mix up your concrete mix according to package instructions in one of the plastic cups, being sure to add enough water so that it forms a thick paste-like consistency. Carefully spoon small amounts of the concrete mixture into both of the plastic cups until they are nearly full and press down lightly with your fingers to even out the surface. Allow them to sit undisturbed overnight or up to 24 hours.

Step 3: Smooth

Once the concrete has hardened, carefully peel each coaster from the cups. If the edges of your coasters are rough, use a sandpaper to smooth them out.

Step 5: Painting

If desired, you can now add color to your coasters by painting them with acrylic paint. Use various colors and designs for an eye-catching effect.

Step 6: Let dry

Once dry, run a glue gun around the edges of each coaster to seal in the paint and protect their surfaces from moisture.

Step 7: Add furniture protection

Cut out felt circles that are just a bit smaller than your coasters. Use your multipurpose glue to glue them on—this will help protect your furniture!

Step 8: Finished )

Now that you have finished making your own concrete coasters, it’s time to show them off! Place these modern works of art on tables or counters throughout your home for a unique decor statement that is sure to impress. Enjoy!

Painted Concrete Coasters Guide

Best cement for coasters

For the best results, you should use a concrete mix specifically formulated for making coasters. This type of mix contains a blend of cement, sand and other additives that will provide superior strength and durability in your finished product. In addition to this, it is important to ensure that the concrete is properly mixed before pouring into your coaster molds - otherwise, it can cause air pockets or weak spots in the final product.

Best sealer for concrete coasters

When it comes to protecting your newly-made concrete coasters, the best sealer for them is either a polyurethane or epoxy sealer. Both products offer protection against moisture and can help prevent staining or fading of your decorative paints.

Polyurethane sealers are clear and provide an invisible layer of protection over the surface of your concrete coasters while allowing the colors to remain vibrant. It is relatively easy to apply and will work great on most types of painted surfaces.

Epoxy sealers are more durable than polyurethanes and offer superior protection against moisture damage as well as UV rays from sunlight. They also allow you to achieve unique effects with color, making them great for creative projects like this.

No matter which sealer you choose, make sure to apply it according to the instructions provided on the packaging. It is important that the sealer be properly applied in order for it to effectively protect your concrete coasters from moisture damage and fading. With regular care and maintenance, your DIY painted concrete coasters should last for many years to come! Enjoy showing off your creative side with these stylish accents around your home or office!

How do you seal concrete coasters?

Once your coasters are completely cured, you can apply a sealer to them. As mentioned above, polyurethane or epoxy sealers both work well for protecting against moisture and UV damage. Be sure to read the instructions on the packaging of whichever sealer you choose in order to ensure proper application. When applying the sealer, make sure that it is spread evenly and thinly across the painted surface - this will help protect your coasters for years to come!

After sealing, how do I care for my concrete coasters?

Caring for your sealed concrete coasters is relatively simple. To keep them looking their best, you should simply wipe them down with a damp cloth when they get dirty. You can also use a mild detergent or cleaner for more stubborn stains, but be sure to avoid any harsh abrasive cleaners that could damage the sealer and painted surface.

In general, regular dusting or wiping with a damp cloth should keep your concrete coasters looking good as new! Enjoy showing off your creative home décor accents with these stylish DIY painted concrete coasters!

Q: Can I clean my sealed concrete coasters with any type of cleaner?

A: For best results, you should only use mild detergents or cleaners when cleaning your coasters. Avoid any abrasive cleaners or harsh chemicals that may damage the sealer and painted surfaces.

Q: How often should I re-seal my concrete coasters?

A: Generally, you should re-apply sealer to your concrete coasters every 6 months or so in order to ensure maximum protection against moisture and UV damage. This will help keep them looking brand new for years to come!

My Personal Experiences with Painted Concrete Coasters: Adding a Pop of Color to Your Home Decor

Painted concrete coasters are a stylish and functional addition to any home. As someone who loves to add a personal touch to my home decor, I was excited to try making painted concrete coasters myself. Through my personal experiences, I've learned a lot about the challenges and rewards of working with concrete and painting it.

One of the biggest challenges I faced when making painted concrete coasters was getting the right consistency of the concrete mix. I found that mixing the concrete in small batches and using a handheld mixer worked best for me. Once I had the concrete mixed, I poured it into silicone coaster molds and let them cure for 24 hours. After the coasters were cured, I was ready to paint them.

One unique perspective I gained from painting concrete coasters is the importance of using the right paint. I experimented with different types of paint, and I found that acrylic paint worked best for me. It provided excellent coverage and dried quickly, making it easy to apply multiple coats. I also found that using a sealant after the paint had dried helped protect the coasters from spills and stains.

Another challenge I faced was choosing the right design for my painted concrete coasters. I wanted to create something unique and eye-catching, so I experimented with different color combinations and patterns. I found that using painter's tape to create clean lines and geometric shapes was a helpful technique.

In conclusion, my personal experiences with painted concrete coasters have taught me a lot about the crafting process and the importance of using the right materials and techniques. While there were certainly challenges along the way, the rewards of creating beautiful and functional coasters for my home were well worth it. As a reader, I encourage you to try making painted concrete coasters and experimenting with different designs and colors. What are your personal preferences for painted concrete coasters, and what unique insights have you gained from working with them?


DIY painted concrete coasters are an easy way to add some creativity to your home decor. With the right tools and materials, you can easily make them yourself - no special skills required!
