| PREPARATION & APPLICATION |
PREPARATION
The substrate must be solid, dry, free of dust, loose parts, paint, wax, oil, rust and traces of gypsum. Cementitious substrates must be cured. Use Yapfix Repairing Montar in case of any loose and uneven substrate to get a sound and flat surface.
The substrate should be protected from sunlight, precipitation and dust for 1 day and application should not be under direct sunlight. Dampen absorbent surfaces to be treated beforehand with water.
MIXING
Pour 0.3 - 0.35 liters of water for application with brush of 0.2 - 0.25 liters of water for application with roller and trowel into a suitable clean container.
The slowly add 1 kg powder component and mix with a low speed mixer to obtain a homogenous lump free mix. Mixing with max 500 rpm mixer is recommended.
Allow to stand for 5 minutes to mature. After remixing for 1-2 minutes, the paste is ready for application.
APPLICATION
Apply a thing layer of YAPFIX waterproofing with brush, roller or trowel, then after 5-6 hours apply a second coat, to have a final thickness of approximately 2-3 mm in the product application instructions insert a 4.5x4 mm mesh in the first layer of Yapfix waterproofing when operation around expansion joints between horizontal and vertical surfaces, areas with small cracks or places subjects to stress.
After the mesh has been lain apply a second layer of Yapfix waterproofing when the first one has set (after 5-6 hours) Use Yapfix Waterproofing within 1 hour of preparation. Unfavourable climatic conditions (high temperature, low humidy , wind etc) can reduce this time to just a few minutues.
Dispose mortars of which pot life is expired. clean tool and hands with a damp cloth.
