Tools you will need.

Before you begin, gather together the following materials and tools:

  • Gloves and face mask. Castable refractory cement will get everywhere, including on your skin. In addition to this being a messy process that you won’t want to have on your hands, castable refractories are not safe for human skin and can cause severe burns if left on for more than a few seconds. Wear gloves at all times when handling castables.
  • A trowel. You’ll need this to spread the cement in a smooth layer across the hearth before it sets up.
  • Protective eyewear is also necessary during casting, as falling particles of cement can be very painful in your eye and even cause permanent damage. If there’s any chance of an accident happening with dribbles or splashes of wet cement, wear protective eyewear over your eyes too!
  • A water source should always be nearby if you’re working with cement products; if an accident happens you’ll want to wash it off immediately in order to prevent burns from setting in deeper than normal (if left untreated). The best way to avoid these is by keeping yourself hydrated throughout this process so that accidents don’t occur due simply from fatigue or lack of attention–use coolers fulla ice water near where you’re working because warm liquids can actually increase dehydration levels!

To start mixing up the batch properly: Fill two buckets halfway with water — one bucket should hold about five gallons while another holds seven gallons — then place them side-by-side so they’re touching each other’s rims (don’t worry if they overflow slightly while doing so).

Determine your container size.

It’s important to plan for the appropriate amount of refractory cement for your project. Determining the amount needed will depend on a number of factors including:

  • The dimensions of your desired kiln shape and size
  • The thickness of the refractory layer desired
  • Whether you’re insulating (you have a shell to hold it in) or casting (you don’t have a form)

The volume of your container is determined by measuring its internal dimensions. For example, if you are using a cylindrical or square pipe, measure its diameter or width, respectively. Next, determine how thick you want your layer to be. Once you have these measurements, multiply them together and divide by 1/2 to get an estimate in cubic feet; this will be a good starting point for determining how much material you need.

If this sounds confusing, don’t worry! A simple way to think about it is that 1lb/cuft = 2 inches thick x 1 sq ft surface area = 50lbs total per cubic foot unit (1’ x 1’ x 2″ thick). So if we go back to our example above where we determined that our container holds 20 cubic feet and we used 3/4″ as our thickness measurement, then we would need about 15 bags of refractory cement for one coat. Another way to look at it: 20 cu ft x 12″ (1 foot) / 6″ (1/2 foot) = 40 lbs per square inch * 3/4″= 30lbs * 20 cu ft = 600 lbs total

Prepare your container for installation.

How to prepare a container for installation:

If your container has a lip, it will need to be narrowed or removed. There are three options for narrowing the lip, outlined below:

  • Option 1: Sanding
  • Option 2: Grinding
  • Option 3: Slicing the Lip Off.

If your container has a hole in the bottom that you wish to seal up, skip ahead to “Sealing Your Container”.

Prepare your Castable Refractory mortar.

Now that you’ve got the details of your measurements and materials, it’s time to start working with the Castable Refractory Cement. To prepare your Castable Refractory mortar, simply add water. Mix it all together until you have a smooth, thick consistency. You don’t want the mixture to be too runny or too dry. Some mixtures require thicker consistency than others so make sure to check before you pour it into your mold.

Mix your Castable Refractory Mortar and pour into the container.

Mix Your Castable Refractory Mortar and Pour Into the Container:

To mix up your refractory mortar, slowly sprinkle the dry mortar into a bucket of water. Keep stirring as you add the dry material. Do not add more than 3 gallons of water to 1 bag (50lbs.) of Castable Mix. Add just enough water to make the mixture wet, but do not over saturate it. The mixture should be about the consistency of oatmeal when properly mixed. Keep stirring until there are no lumps in your mix anymore, and be sure to stir for at least 5 minutes to ensure that all materials are evenly distributed

Prepare for the first fire.

To begin, set the oven temperature to between 100-150 degrees F. Place your oven in the desired location and allow it to heat up. Do not exceed 200 degrees F at any point during this process. Keep in mind that the oven will be hotter than the temperature of the oven, so please use caution when standing near or around it.

The purpose of this first fire is only to dry out the cement, not to get it hot enough for cooking yet. Use this time period as an opportunity to make sure there are no leaks in the door seal or cracks anywhere in the insulation that need patching before you install your door again and start cooking! Do not leave your first fire unattended – remain in close proximity so that if any problems arise you can tend to them immediately.

If everything looks good after a few hours at low heat, then move on to Step 5: Cure Your Oven for Cooking!

Hot Fire up to cure.

Once you have finished your cast or layed up your refractory lining, it is time to cure the product.

A good way to do this is to put in a few firebricks and burn a small fire in the unit for a few hours.

This will dry out the refractory and make it ready for service.

The linings usually come with instructions on how hot they need to be cured at so make sure you follow them closely.

Once you have cured your castable cement, it is ready for use!

Finish curing fire up to 2300 degrees F.

Setting time can vary according to how warm the ambient temperature is. Higher temperatures will accelerate the setting process, while cooler temperatures will slow down the setting process. 24 hours is the usual setting time for this material, but it can be increased by keeping it in a cool place or decreased by keeping it in a warm place.

You can install your castable refractory cement yourself, it just takes the right tools, instructions, and patience!

The installation of your castable refractory cement is an easy process, but it can take some time to make sure the job is done right. The good news? You don’t have to be a professional to install castable refractory cement yourself! With a few simple tools and the following tips, your new fireplace will be ready for use in no time.

  • Wait until the weather is clear and dry for at least 24 hours before you begin any work on your fireplace. Make sure that all materials you need are measured and cut before beginning the project so it runs as smoothly as possible.
  • When applying any coating or sealant to your chimney, have another person ready with a wet sponge to smooth over any mistakes or uneven areas. Applying too much of the sealant can lead to smearing and dripping, so make sure not to extend past what is recommended per square inch in order to avoid these issues! You should also wear protective gear while working with any chemicals or paints used during this process because they may cause irritation if contact occurs on skin or eyes.

In this post, we’ll be talking about how to install your castable refractory cement.

The first thing you’re going to want to do is wait until there’s an open firebox. This means that the firebox has cooled down to a safe temperature and is ready for installation. You can test the firebox’s temperature by touching it with the back of your hand or a clean oven mitt—if you need the mitt, it’s not cool enough yet. If it’s too hot, turn on the fans to help cool it down faster.

Once the firebox has cooled, grab your shovel and get ready to start pouring!

Fill your shovel with castable refractory cement, and pour it into the firebox while walking backwards so you don’t make a mess.
