Instructions for use

Special recommendations

The creation of design features with a thicker coat of render is possible on selected areas such as stone piers, cornices at roof and storey height, or at ground level.
The following thicknesses should not be exceeded:

30 mm on masonry (blockwork and new render)

20 mm on concrete or existing render.

    For thicker coats please contact SODAMCO Weber.
    Do not apply weberpral F under rain or on frozen surface ,or where there is a risk of rain or frost within the next 24 hours. Avoid application under full sunlight or in strong winds.
     

Surface preparation

The background surface to be rendered must be free from contamination, dirt, curing compound, releasing agent, laitance...

  • Concrete blocks masonry, clay bricks, absorbent rough concrete and render
  • Fill any open joints and voids by dubbing out with weberpral F according to good working practices.
  • Smooth concrete / dense concrete
  • Roughen the surface by mechanical scabbling, or apply suitable Premix RushCoat with heavy stipple finish.
  • In hot weather and dry winds, wet the substrate before application by spraying water in order to prevent premature drying of weberpral F. Wait until the film of water has disappeared before applying weberpral F. It is recommended to use plastic sheeting to protect fresh applied render from wind and direct sunshine. Do not allow the plastic to touch the finished surfaces.

Product preparation

Mix weberpral F with 3.7-4.7 liters of clean water per 25 kg for 5-10 minutes maximum in a mortar pump.The mixing rate and mixing time must be constant to avoid shade variations after drying.

Product application

1-FOR DECORATIVE WATERPROOFING MORTAR
Scraped finish
Spray directly a layer of 15 mm thickness (two passes, allow the first pass to stiffen slightly before applying the second pass) onto the prepared substrate and then level out. When the surface is hard enough, scrap it. The timing to start this process is when the material does not stick on the scrapping tool. Depending on weather conditions, this may vary between 1 and 16 hours.The minimum thickness should be 10 mm throughout after scraping.
2-FOR DECORATING CONCRETE AND MASONARY
Scraped finish
Spray directly a layer of 10 mm thickness (two passes, allow the first pass to stiffen slightly before applying the second pass) onto the prepared substrate and then level out .When the surface is hard enough, scrap it. The timing to start this process is when the material does not stick on the scrapping tool. Depending on weather conditions, this may vary between 1 and 16 hours. The minimum thickness should be 6 mm throughout after scraping.
Next day lightly brush to remove dust and spray with a light mist of water 2 times per day for 2 days.
