Frequently Asked Questions

Builders Cement is a popular cement blend designed for masonry applications and is typically used for:

  • Brick and block laying (mortar work)
  • Rendering and patching walls
  • General masonry and repair work
  • Non-structural construction applications
  • DIY building and landscaping projects

GP Cement is a base ingredient, meaning it is designed to be mixed with aggregates and sand to create concrete. Using GP Cement as a base ingredient gives you greater control over the mix ratios and allows you to customise your mix to suit your project.

Builders Cement is a blend of Portland cement and fly ash that is designed to improve workability for brickwork, blockwork, and rendering. It is pre-blended to provide specific properties but still requires mixing with sand and aggregates to create the final mix.

Builders Cement can be used for a number of applications, so your mixing ratios will vary depending on whether you are laying brickwork, blockwork, or rendering.

STEP 1: Measure the required amounts of Builders Cement, sand, and aggregate for your project, then place the dry materials into a clean wheelbarrow. Blend the dry ingredients thoroughly.

STEP 2: Slowly add clean water while mixing until you achieve a smooth, workable consistency. Only add enough water to suit the mix, as too much water can reduce the strength of the finished product.

STEP 3: Apply the mix as soon as it has been prepared. Once placed, keep the finished work moist for approximately 7 days to achieve the best results.
