Materials Needed for Resin Alphabet Letters

First, you must gather all you will be needing to get started. You can purchase everything separately, however, there are many useful kits available that provide everything for you. The kits can usually save you some money as buying things separately can add up. Although, some might say the opposite is true. 

So, do what would make things simpler and more affordable for you.

You will need to choose the correct resin for your particular needs. For example, you will need a casting resin for letter molds. Always check the directions and other information on the product label. Below is a list of the materials needed to make resin letters.

  • Resin and hardener
  • Letter molds for resin
  • Disposable protective gloves
  • Two or more plastic cups
  • Mixing sticks
  • Add-ins like beads, glitter, or dried flowers (optional)

Embellishments for Resin Art Letters

  • Color Pigment (optional)
  • Resin mat or piece of cardboard to work on
  • Baby wipes, just in case you mess
  • Toothpicks
  • Acetone or nail polish remover
  • Heat gun or lighter

In most cases, working time is important, so setting up your work area before you begin is important. Choose a working area where you can leave everything and try not to work at your dining room table which you might want to use later. The room you work in must have plenty of air circulating. Although many of the products today have low to no odor or fumes, it is always a good idea to have enough air circulating in the room you are working in. So, your very first step would be preparation.

The workspace should also be clean and have as little dust as possible as these little particles of dust can cause some problems if they land on your curing resin item. Your mold and tools should also be free of dust and clean to use. Set out everything you are going to be using from your working mat, resin, and molds to your measuring cups, stirring sticks, and glitter. To work on it, you can also lay down some plastic sheeting or use a sheet pan. To prepare yourself, make sure to wear gloves as you do not want any resin to get onto your skin.

If you do happen to mess some on your skin, you should remove it immediately with the baby wipes or a paper towel and some acetone.  Even a little lemon juice on the spot might help to remove the resin. Finally, rinse the area with some soap and water.

Most of the resin products have low to no odor, so wearing a mask is optional, but read the product instructions carefully before you begin, just to make sure. You can also wear an apron if you are afraid that you might mess on your clothing. To help prevent the formation of bubbles, some recommend that you warm up your resin and hardener before using it, but this is optional. Once you have cleaned your mold, you can apply an anti-adhesive spray so that the casting will come out easier, preventing any tearing. Some molds may not need this, but it is always an added precaution for best results.


Mixing Your Resin

You can then add your glitter or other small items to the bottom of the mold. Once everything has been prepared, you can then move on to mixing your resin. Most products, besides UV resin, come in two forms, your resin, and hardener. You have to mix these two materials to create your resin casting. Remember, to wear your gloves when you work with the resin. You will need to calculate how much resin is needed for your chosen mold. For an entire small letter set, it could take anything from 100 ml to 130 ml of hardener and resin.

Easy Resin Alphabet Letters

Always make sure you use the right amounts and mix them in a 1:1 ratio, which means you will need the same amount of hardener and resin. Some resins work with different ratios, so always check. This is essential because if the measurements are wrong, the resin will not cure properly. This is where your plastic measuring cups come in handy. Measure out your resin and hardener in separate cups, then pour both into another measuring cup. Then, take your stirring stick and mix the two components well. Mix slowly to stop any excess bubbles from forming. If you want, you can now mix in your pigment powder. The mica pigments are concentrated, so add small amounts.


Pouring Your Resin Into the Molds

Slowly pour your resin mixture into your mold and over any inclusions until it reaches the brim. You can check, by going eye level with the mold, to make sure it is filled. For larger, deeper letters, you can also lay down a thin layer of resin first, and then add in your inclusions and wait for this to cure before adding another layer. This works great if you want to add some battery-powered fairy light to the resin to make a resin letter light.

Maybe you poured too much? Do not panic, take a dropper, suck out some of the poured resin and place it into another letter.

You will have to work quite quickly as the resin starts to harden. If you have left it, and the resin hardens, once you have removed the cured items, you can try and sand off any excess pieces. Once you have done pouring your resin, you can then move in and pop any bubbles. You can either use a toothpick to pop the bubbles, or a heat gun to remove the bubbles. You can even try using a straw to blow over the surface. Wait a few minutes and then check to see if any more bubbles come out and remove them.


Curing and Demolding

Allow the resin to cure for at least 24 hours, if it remains sticky to the touch, leave for another 24 hours. If, after this time, the resin is still tacky, something went wrong, and you will have to start over. Once the resin has cured thoroughly, you can then pop them out of the mold. When using a good quality mold and if you used mold release spray, you should have no problems with the mold tearing or scratching your casting. Clean your molds with some soap and water or wipe them off with some of the baby wipes.

Frequently Asked Questions


Must You Apply Mold Release Spray Before Pouring the Resin?

The best quality resin molds do not need you to spray mold release onto the surface before pouring the resin. However, in some cases, the mold release spray can help but it may affect how the resin looks once it cures.


Are Silicone Molds the Best Material for Resin Molds?

Yes, silicone is an excellent choice because it is durable, flexible, easy to use, and clean. The rigid plastic molds are difficult to use and are not flexible like the silicone molds. They might cost a bit more, but they provide much better results and can be used more than once.


What Are Some Resin Letter Ideas?

There are so many creative ideas for resin letters, depending on the size you like to use. Smaller resin letters are great for key chains, pendants, or they can be used by the kids as a learning aid. Larger resin letters can be used as décor items, lamps, or a centerpiece at an event.


How Long Must You Wait for Resin Letters to Cure?

You must be patient for this part of making resin letters. Wait for at least 24 hours for the resin to cure, and if it still feels a little tacky, wait another 24 hours to fully cure before removing it from the mold. Make sure to leave the resin mold somewhere where it will not be undisturbed.


Can a Hairdryer Be Used to Get Rid of Bubbles in Resin?

You need quite a lot of heat to remove the bubbles from the resin, so a hairdryer will not do a good job as it will not produce enough heat to work. The hairdryer can also blow dirt and dust all over the resin. Rather use a heat gun, or for smaller projects, using a toothpick to pop the bubbles can work.
