Drymix Mortar Application Guide


Drymix Mortar Application Guide

Drymix mortar, also known as dry mortar or dry-mix mortar, is a mixture of cement, sand, and additives that is used for various construction applications. It is pre-mixed at the manufacturing plant and requires only the addition of water on the construction site. Drymix mortar offers several advantages over traditional wet mortar, including improved quality control, faster application, and reduced wastage. Here is a general guide for the application of drymix mortar:

  1. Surface Preparation:
    • Ensure that the surface to be covered with drymix mortar is clean, free from dust, grease, oil, and any loose particles.
    • Repair any cracks or damages in the substrate before applying the mortar.
  2. Mixing:
    • Drymix mortar is typically supplied in bags or silos. Follow the manufacturer’s instructions regarding the mixing process and the water-to-mortar ratio.
    • Use a clean container or mortar mixer to mix the mortar. Pour the required amount of drymix mortar into the container.
    • Gradually add water while mixing to achieve the desired consistency. Mix thoroughly until a uniform and lump-free mortar is obtained.
  3. Application:
    • Depending on the application, there are different methods of applying drymix mortar. Here are some common techniques:
      • Trowel Application: Use a trowel to apply the mortar directly onto the substrate. Spread it evenly, ensuring complete coverage.
      • Spray Application: Utilize a spray gun or mortar pump to apply the mortar onto the surface. Adjust the nozzle and pressure to achieve the desired thickness.
      • Pointing or Jointing: For filling gaps between bricks or tiles, use a pointing trowel or a mortar bag to force the mortar into the joints. Strike off any excess mortar.
  4. Finishing:
    • After applying the drymix mortar, it is essential to finish the surface for aesthetic purposes or to achieve specific functional requirements.
    • Use appropriate tools like a trowel, sponge, or brush to achieve the desired texture or smoothness.
    • Allow the mortar to cure as per the manufacturer’s instructions before subjecting it to any loads or finishing touches.
  5. Cleaning:
    • Clean any tools, equipment, or surfaces that come in contact with the drymix mortar immediately after application. Once the mortar hardens, it becomes difficult to remove.
