About This Class

In this class, we will be creating a small home decor project: candle holders, to learn how to create the terrazzo effect, using acrylic resin.

Terrazzo is a very trendy material right now and its main advantage is that it can be customised with any colour, to match your home decor atmosphere.

I will teach you how to accomplish this amazing effect using acrylic resin.

Acrylic resin is a fantastic material that is easy to use and environmentally friendly.

I will show you where to supply this material, all the names it can have (Acrylic One or Jesmonite, to name a few… ) I will also explain to you how to use it at its best potential and tips and tricks to ease the casting process.

Then, we will do together small candle holders, with little material and tools you probably already have at home, so you can give it a try.

My goal is that at the end of the class, you will be able to use the same technique for many other home decor projects. Terrazzo is the perfect effect to exercise both personal style and creativity. Because truly, the possibilities are endless !

This is a class for creatives and makers who wants to learn how to achieve this effect for their own DIY home decor projects, or furniture upcycling.

Students can be complete beginners with acrylic resin for this project.

1. Introduction: Hi everyone, welcome to our class, where we will be creating a small ome decor project to learn how to create the terrazzo effect using acrylic resin. My name is Claire Iglesias And I live in Brittany, France. I've been an interior designer for 14 years and I am also a maker. I love to create things with my hands and learning new skills. I run a small home decor brand named Mon Petit Navire where I share my passion for the architectural textures in home decor, creating objects with terrazzo and marbling finish. Today, I would like to share with you how to achieve the terrazzo effect using acrylic resin. Terrazzo is a very trendy material And its main advantage is that it can be customised with any color color to match your home atmosphere. I will teach you how to accomplish this amazing effect using acrylic resin. Acrylic resin is a fantastic material that is easy to use. And environmentally friendly. I will show you where to supply it and how to use it. Then we will do together a small home decor project, Candle holders. with material and tools you probably already have at home, so you can give it a try. My goal is that at the end of this class, you will be able to use the same technique for many DIY project. The terrazzo is the perfect effect to exercise both personal styles and creativity because the possibilities are endless. This is a class for creatives and makers who wants to learn how to achieve this effect for their DIY project or even upcycling furnitures for instance. Students can be complete beginners with acrylic resin for this project. In the next video, I will be discussing the project in more details. So see you there. 2. Class Project: The project for this class is to create small candle holders with 3 colours using only two primary colours, blue and red. This is a great way to dive into the terrazzo effect. With very few material and gives you the keys to go further and make big DIY project. So let's get started. 3. What is Acrylic Resin ?: In this lesson, we will dive into the specifications of the material we will use: Acrylic resin. Because it is always important to understand the capabilities of a material to use it at its best potential. Acrylic resin is a common ingredient in latex paint, but it is rather new to use it for casting project. It is a two-component material consisting of a mineral powder and a water-based acrylic resin These bind in such a way that a very strong material is created completely fire resistant. The main advantage of this material is that it is environmentally friendly. It is non-toxic and solvent free. And unless other resins it doesn't emit any solvent emanations So you can safely use it for your project. There is no heavy smell and all the tools can be washed with water afterwards. This is a pretty common material used for theatre or movie decors. It can be used to replicate the appearance and textures of any surface finished in any numbers of colours. Now that you know more about the material, where to find it ? well this material is hiding behind many names and brands. Here is some of them: Acrylic One Jesmonite, Plasticrete Acrystal. Best is to buy it directly from the brand to have better prices. They often propose starter kits to begin with and see if this is a material you like to work with. Depending on which country you live. One brand might be more available than another, but it is also possible to find it sometimes in your local craft store if there is a casting or molding section. So be sure to check that option as well. I use myself the material from Acrylic One this is a great quality and I highly recommend it. I listed all these brands in the recap sheet that you can find in the resources section of this class. So you can check what it is the best option for you. To prepare the acrylic resin. It is super-simple and the instructions are always the same no matter what brand you are using. Liquid is mixed with the powder enough to create a thick white liquid. However, ratio between liquid and powder, may slight change between brands. So be sure to check the instruction manual provided with the material, but it is possible to colour the mix with natural or metallic pigments. Pro-tip: I noticed that liquid pigments can have brighter colours than powders pigments. So it is up to you and the effect you would like to achieve. In the next lesson, we will go through all the material you will need to accomplish this first small project. And you will see it doesn't have to be fancy or expensive. See you in the next lesson. 4. Supplies Needed: In this class we will check all the materials you need to create the project. First, you will need a clean workspace large enough to work protected by a plastic table cloth As an alternative, you can reuse plastic packaging or plastic bags to protect your table. Then of course, you will need acrylic resin. I will explain to you later how to calculate how much resin you need for this project. For this particular project, we will need about 450 grams of mix material. Now, the acrylic resin I use is from Acrylic One. Their ratio to mix the components is: one portion of liquid for two portions of powder, which means to obtain 450 grams of material, we will need 150 grams of liquid and 300 grams of powder. So double-check on your side, what are the specifications for the brand you use as the proportions can slightly change between brands Pigments, we will need about two primary color, blue and red I use liquid pigments but natural powder pigments can work as well. To make the candle holders will the terrazzo effect, in addition to the acrylic resin material and the pigments, you will need some other materials all easy to find. Maybe you already have it in your kitchen. We are going to make 3 candle holders. So for the molds we will need 3 yoghurt pots, the one made with terraformed white plastic. Clean and dry it carefully and keep it aside. Then you will need three tea-light candles You will also need the small weight of 20 grams each. As an alternative. You can use, for instance, little stones of about the same weight. A kitchen scale, a big spoon, a pair of scissors, and a cutter Six paper cups. 4 wooden spatulas You can even keep the one's home your ice creams after cleaning it carefully. 3 plastic sheets. It can be as simple as freezers bags, or plastic bags that you cut to have enough plastic surface. And finally, for the sanding part, you will need a cloth Some household gloves. A bowl of water. A sponge. And sandpaper Now, this part is important. You will need ideally 3 different grits like 80 grit to start and reveal the terrazzo effect. Then 240 grit and finally 400 or 500 grit to polish the candle holders and give it a smooth effect. Pro tip. Always use wet and dry sandpaper as acrylic resin needs to be sand with water. When the holders are finished to sand, as an option, you can apply a sealer on it to protect it from stains and give it a satin or shiny effect. For instance. This is not mandatory for this class as this is small pieces. But if you consider doing larger pieces, buying a sealer from the same company you bought the acrylic resin might be good to consider. It will protect your creations longer. It will brighten the colours and give a nice matte, satin or shiny touch, depending on the finish you choose. You will find in the Resources section of the class a written list of all the supplies for this class. Alright, we are ready to move on. See you in the next lesson. 5. Part 1: Making the Terrazzo Chips: In this lesson, we will start the fun part: the terrazzo chips Acrylic resin dries very quickly. So be sure to prepare all your material on hand to not lose any time The first task is to determine what quantity of material to prepare for the molds. A good trick is to pour water in the mold and to weight it. Then multiply this number by 3 It will give you a good hint on the final weight of the pieces you will produce. It's not an exact science, but it's a good start to determine the weight you would need when you never use the mold before. So we will do that exactly. I take my scale, put a cup on it and tare the scale to 0. Then I put water on it until half of the height Here it is. The scale indicates 50 grams of water. If we multiply this number by 3, it means that we will need about 150 grams of acrylic resin to accomplish one candle holder. Pro tip. Another good rule to remember doing terrazzo is that you want your terrazzo chips to be about more or less 1/3 of the total weight. So for today's project, we will make 60 grams of colored chips and 90 grams of base for each holder. We will make 3 colors for these chips, blue, red, and purple. First, put an empty paper cup in the kitchen scale and tare the weight to 0. For each color, you will need to weight out 20 grams of liquid in one paper cup. 40 grams of powder in another paper cup Pour slowly the powder into the liquid, stirring well with a wooden spatula. When the textures became a thick white liquid. Then it's time to add the pigments. Pro tip A little pigment goes a long way. Be careful, to get your desired color. You will need to build the colour as you go. One drop at a time. As discussed, we will use 2 primary colors, blue and red, do not exceed two grams of pigments in the mix because too much pigments can change the setting time or even prevent it from setting. Too much pigments can also cause the finished product to lose some of its mechanical properties. Of course, you can go with any color that you want. The possibilities are endless. You will have to work quickly as acrylic resin dries very fast. You will have around ten minutes to create your color before it starts to dry. When you are happy with your color, place your first plastic sheet in front of you. And using the wooden spatula, pour slowly the mix from the center to the edges make sure to get all of the mix out of the cup and onto the sheet Pro-tip The good thickness for terrazzo chips should be between 1 & 2 mmm thick So it is easy to crush, but not to crumbly either Then let it dry around 20 minutes. During this time, you can run the same process for the two other chips colours And here it is, the 3 colors have dried Now it is time to crush it into little pieces. This is by far my favorite part of the process. Do the same for all colours until you are happy with the size of your terrazzo Chips. Here you go. We've done bespoke terrazzo chips Now leave it on one side and see you in the next lesson to make the terrazzo base. 6. Part 2: Making the Terrazzo Base: In this lesson, we will start doing the terrazzo base Prepare the molds and remove the tealight candles from the metal part Keep the metal part for now and put the candles aside Remember, in the previous lesson, we determined that we needed 90 grams of resin to make the base of each candel holders Which means that for 3 candle holders, we will need 270 grams of material I will stick to the white color for this one. So I don't need the pigments. So for the base, we will follow the same ratio as for the chips and weight out 90 grams of liquid in one paper cup and 180 grams of powder in the paper cup we previously used for that. Slowly pour the powder into the liquid, always stiring well with a wooden spatula. When the textures became a thick white liquid, it's ready. It can take a few minutes. You really want to have a smooth consistency at the end, without any lumps When your base is ready, It's time to mix the terrazzo chips Pour the chips in and mix together, making sure all the ships are coated When you're done, tap the sides of the paper cup to let any air bubbles rise to the surface. Now, take your molds and start pouring. Making sure you pour into the center of the mold. First. When you used all your material, give a gentle shaketo the molds to release some of the air pockets. You want the visible surface to be as smooth as possible to avoid too much sanding process have doubled. Finally, take the metal of the tea-light candles and push it gently in the mix until the edge is flush with the terrazzo mix Take your time. You don't want the resin to come into the metal base. Then put some weights or stones to prevent the metal base to go back up. Now, it's time to let it dry for around 30 minutes. Now you pieces should be dry to the touch and ready to take of the mold If not, leave it a few minutes more to drag. Using your scissors and your cutter cuts in the molds and gently peel back the edges to remove the then carefully remove the metal holders as well. Using the scissors if needed. you have casted your candle holders. See you in the next lesson for the sanding part to reveal the terrazzo chips. 7. Part 3 : Sanding the Pieces: In this lesson, we will accomplish the most rewarding part. Sanding the pieces. You wana wear gloves for this part, not because it is toxic or anything, but because it can be very dirty for the hands. But any dirt can be easily washable with soap and water, so it is totally optional and up to you dip the 80 grit sandpaper into the water and put it on the table. Put the top surface of the candle holder, onto the sandpaper and start to sand. Pro tip: You want to sand down in circular motion to avoid doing too much big scratches on the pieces`. Then sand down to remove any rough edges and we reveal the terrazzo chips. Keeping dipping the paper into the water, as you sand from time to time, clean the pieces with a wet sponge to see your progress. If using the 240 grit and then the 400 grit sandpaper. Repeat the same process to polish the pieces. When you have sanded and polished the pieces use the cloth to dry it and leave it to dry for 30min. If you decided to use a sealer on your pieces now is the time to apply it. It will give a nice touch to your pieces and protected from any stains. Just follow the instructions of the sealer you have chosen. I dilute mine with a small amount of water and apply it with a dry cloth. Then let it dry for a few more minutes. And it's done. This little guys are finally finished and they look amazing. See you in the next video for some final thoughts on the project. 8. Final Thoughts: So this is, we made small candle holders using acrylic raising to achieve the terrazzo Effect. I really hope you guys enjoy this class and I hope it inspired you to actually start your own home decor projects using this technique. And that you're excited to try some creative experiments with this material. I cannot wait to see your creations and the color you choose. You're free to share your experiments below in this class, I will definitely have a look and give you advice. Or you can share your project on Instagram with the hashtag #monpetitnavireclasses So I will be able to see it and give you tips and feedbacks. It's gonna be super cool and I'm really excited to see what you're going to come up with. Thank you so much for enrolling this class. And I wish you a lot of fun with terrazzo making .
