Gyplast Fix

Gyplast Fix is a fast setting plaster in the form of whitish powder, ready for manual application after the addition of the specific amount of water. It’s mechanically mixed and automatically packed with constant tested ratios, composed from primary raw materials and high quality additives enhancing the product performance. Natural elements compose more than 98% from the total weight. After adding the right portion of clean water, it gives a homogeneous mortar ready for application without adding any additives. It has the ability to level edges and corners especially in contact with concrete beams, giving it an unbreakable edge, whitish appearance in addition to completion in shorter duration. It is used to prepare leveling screeds and spots without the need to remove them in future especially if the surface will be leveled using “Gyplast Fill”

Gyplast Fix after its setting gives a very thick coat. It also features a very high adhesion to concrete and all types of bricks substrates without the need for cement slurry projection, in addition to a very high worker productivity per day with the lowest percentage of waste and an adapted setting time for site needs.

Key facts

  • Perfect for applying vertical and horizontal screeds and spots with a large range of thicknesses
  • Ideal for applying in edges, corners or installing galvanized steel edges and plastic mesh tapes in construction separations
  • Ideal for electrical and carpenter repairs
  • Doesn’t require removal of screeds and spots after levelling
  • Doesn't contain cracks or separate from the application of Gyplast Fill or traditional plaster
  • Very strong surface allowing accurate levelling
  • Rich with adhesion additives improving adhesion to different types of substrates
  • Minimal waste compared to traditional methods
  • Whitish surface
  • Easy to handle and store resulting in better organized and clean site
  • Easy to prepare, only spray the powder to water with the right ratio and mix till reaching the required consistency
  • Easy to apply, especially when applying vertical screed resulting in better plasterer productivity and job quality
  • Adjusted setting time from 15-20 minutes


Before starting:

Substrate must be sound, free from dust, loose particles, cement laitance, curing compounds, oil, grease or any other contamination.

Ensure the mixing container and the application tools are clean especially form waste of previous mix and it’s recommended to clean the tools directly after usage .


Gyplast Fix is sprayed on water with the right ratios (Don’t add water to powder), then leave for 2 minutes till it soaks completely. Stir the mix perfectly in all directions till reaching a homogeneous mortar with the convenient consistency for the application. It is preferred to use mechanical mixing.

Gyplast Fix is workable for 15 minutes starting from the start of mixing, initial setting in 20 minutes and reaches final setting in 1 day on average according to surface conditions, and thickness, weather conditions and humidity.

Gyplast Fix can be applied to make screeds either vertical (recommended) or horizontal and doesn't require to be removed after plastering.

Also Gyplast Fix can be used for wall repairs, installation of electricity pipes, door and windows fitting.
