Gyplast Mortar

Gyplast Mortar is a thick smoothing plaster for rough substrates 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. This is product has the ability to act as a first thick smoothing coat for rough substrates either Gyplast Fill or traditional sand & cement plaster to repair it in order to reach the required lining.

Gyplast Mortar after its setting gives a hard and smooth coat. It also features a very high adhesion to different types of substrates especially Gyplast Fill with lowest percentage of waste.

Key facts

  • Rich with adhesion additives improving its adhesion to different types of substrates
  • The consistence of the mortar after mixing with water and cohesion additives included in its formula reduces significantly the application waste compared to traditional methods
  • Gives a very hard smooth whitish surface
  • At the end, the final surface is a whitish, strong and decorative rough texture
  • Easy to prepare, only spray the powder to the indicated ratio of water then mix thoroughly till reaching the required consistency
  • Average coverage rate (Lab trials ) reaching 900  m2/Ton at a 1 mm thickness, according to type and roughness of substrates
  • Adjusted setting time ranging 60-70 minutes according to application and storage conditions
  • Easy to handle and store, resulting in an organized and clean working site
  • Guaranteed by Saint-Gobain Gyproc, the world leader manufacturer and producer of building materials
  • Very healthy both during application or housing and doesn’t cause any odors
  • Environment friendly as it consumes a low thermal energy during manufacturing and it is packed in recyclable  sacks
  • High productivity compared to traditional ways
  • Energy saving resulting from good thermal insulation
  • Build thickness in short time
  • Saves the cost and time of wall smoothing
  • Perfect as a thick smoothing coat for the surface of Gyplast Fill
  • Perfect to repair traditional plastering method especially for very rough surfaces
  • Optimum for large areas because after setting, Gyplast Mortar doesn’t show the jointing between different areas applied on a long interval of time making it perfect for repairs  and maintenance

Application

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

Preparation:

Gyplast Mortar 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 Mortar is workable for 40 minutes starting from the start of mixing, initial setting in 70 minutes and reaches final setting in 2 days on average according surface conditions, and thickness, weather conditions and humidity.

Gyplast Mortar is applied on top of Gyplast Fill or traditional plaster. Apply it till filling the substrate roughness. Don't over smooth Gyplast Mortar to get very smooth surface
