Ever looked around your home and thought, “I wish I could spruce things up with some unique decor?”  Well, get ready  because we’re diving into the world of resin casting, and it’s all about creating unique decor that’ll have your friends asking, “Where did you get that?” Resin casting is like a hidden gem in the crafting world, allowing you to embellish everything from books, furniture, wall art, and more. In this blog post, I want to show you how easy it is to transform a simple acrylic block into something stunning! So, grab your gloves, clear your workspace, and let’s learn the art of resin casting – the coolest way to make your home uniquely you!

Create Beautiful Home Decor!

Just so we’re clear; Resin casting is different from Resin coating.  Resin casting means you are pouring resin into a silicone mould and letting it cure.  Resin coating is pouring resin on top of a surface for a glassy finish.   For this project,  I’ll be using a Urethane Resin or its’ more common name, FastCast resinEpoxy resin can also be used for casting, but I use it mostly for coating my projects.  For further explanation on Resin casting vs. Resin coating,  head over and read this blog post.

Steps to Resin Casting

  1. Measure Resin ratios
  2. Stir resin for appropriate time
  3. Pour resin into mould
  4. Let cure
  5. Paint

Step 1: Measure

Using a clean measuring cup, pour in equal amounts of Part A and Part B of your FastCast Resin. Note:  Measurement is by volume not weight; so if you pour in Part A to the 1 oz. mark on your cup, then you would pour in Part B up to the 2 oz. mark.  Also, no more than 3 total ounces should be mixed at one time because the cure rate is very quick.

Step 2: Stir

For stirring, follow the instructions for the particular brand you are using! This is really important! Some brands will have you use one cup for mixing and some brands require two.  In either case, the stir time is somewhere between 30 and 60 seconds.

Step 3: Pour

Quickly pour resin mixture into mould.


Step 4: Let Cure

Let cure for 5-10 minutes, then pop casting out of mould.

Pro Tip: If for some reason the casting does not come out properly cured, i.e., it’s sticky or not hard, I’ve got lots of tips and solutions for you in my Beginner’s Resin Guide .

Step 5: Paint

Resin castings can easily be painted! I used a clay based chalk paint by DIY because it sticks to most anything.  The cured castings  have a  slick surface so this paint works great!  It’s also easily blended using a little bit of water on your brush.

Pro Tip: The castings can also be “colored” before you even pour the resin.  Pigments such as DIY Making Powders can be brushed in the moulds prior to pouring the resin for a beautiful finish.  For more information on that read the blog post HERE.
