Brick or block laying

  • Bricks or blocks must be free of dust, at a temperature of +15 oC - +25 oC.
  • ALFAKOL 1* is similar in application to conventional mortars.
  • Joints between bricks should not exceed 10mm.

Plastering

  • Allow 3-4 weeks after brick laying before plastering.
  • After you place the level guides, apply the plaster by spraying it or manually with a plastering trowel at a thickness between 10 and 12 mm in one layer.
  • If more thickness is required, the application should be done in two layers. The 1st layer should be roughened then cured. Protect the newly applied plaster from sunshine and wind. The new plaster has to be cured with water for at least three days by spraying 3 to 4 times daily.

Substrates preparation

  • The substrate must be solid, free of dust, loose parts and oils. To avoid immediate absorption of mix water by the substrate and for better adhesion saturate the surface to provide a saturated surface dry condition.

Preparing the mix

  • Pour the material into clean water and mix (mix in a concrete machine for big quantities or with a low speed electric mixer for small quantities) until a homogeneous lump free mix is obtained. Allow mixture settle for 5 minutes prior the application. Attention! Additional water will make your mixture sloppy and may cause negative results on final strength.
  • Use the mixture when is still fresh. Do not leave the mix unmixed for a long time. Do not mix with water or latex additive when the mixture starts to set in the bucket. In such case the mix should be dropped.
