Key Features

  • Heat Resistance: As mentioned earlier, Dap High Heat Mortar can withstand temperatures up to 2000°F (1093°C). This makes it perfect for high heat applications where traditional mortars would fail.
  • Pre-Mixed Formula: Unlike traditional mortars that require mixing with water, Dap High Heat Mortar comes in a convenient pre-mixed formula. This saves time and effort by eliminating the need for preparation.
  • Durable: This mortar is highly durable and can last for many years without cracking or deteriorating. It can also resist water and chemicals, making it suitable for various environments.
  • Ease of Use: The pre-mixed formula of Dap High Heat Mortar makes it easy to use even for beginners. It has a smooth consistency that makes it easy to apply with a trowel or gloved hand.
  • No Shrinking: One common issue with traditional mortars is shrinking after application. However, with Dap High Heat Mortar, you don’t have to worry about this problem as it does not shrink or crack once applied.

How to Use Dap High Heat Mortar

The application process of Dap High Heat Mortar is relatively simple and straightforward. Here are the steps to follow:

  1. Clean the surface where you will be applying the mortar thoroughly. Make sure there are no loose debris or dirt as this can affect the bonding of the mortar.
  2. If the surface is extremely smooth or non-porous, roughen it up using sandpaper or a wire brush to create a better bonding surface.
  3. If necessary, dampen the surface with clean water before applying the mortar.
  4. Scoop out an appropriate amount of mortar using a trowel or gloved hand and apply it onto the surface. Make sure to spread it evenly at a thickness of 1/8 inch (0.32 cm).
  5. You can then shape or mold the mortar using your fingers or tools before it dries completely.
  6. Clean up any excess mortar immediately using a damp cloth before it hardens.

Tips for Using Dap High Heat Mortar

  • Drying Time: The drying time of this product may vary depending on temperature and humidity levels. Generally, it takes around 24 hours to dry completely at room temperature (77°F/25°C).
  • Curing Time: To achieve maximum strength and durability, allow the mortar to cure for at least seven days before exposing it to extreme heat conditions.
