BEST WATER LEAK BINDER LAMPOSILEX ME PREPARATION
                     BEST WATER LEAK BINDER LAMPOSILEX ME PREPARATION
LAMPOSILEX ME 
Ultra-fast setting and curing hydraulic binder for stopping water leaks. Here is the product 
preparation of this perfect ultra fast water leaks binder from Mapei.
Preparation of the substrate
Sealing water leaks
· Enlarge the cracks or dovetail holes so the wider part is towards the outside. The minimum external
sizes must be about 2 cm in width and 2 cm in depth.
· Remove any incoherent material from cavities.
Waterproof sealing of rigid joints
· Remove any degraded or loose material and clear all dust by means of compressed air.
· Thoroughly wet the substrate with water.
Before sealing, wait until any excess water has evaporated.
Compressed air or a sponge can be used, if necessary, to facilitate the removal of unabsorbed water. 
The ideal condition would be a cavity saturated with water but with a dry surface.
Preparation of the mix
While stirring, pour 1 kg of Lamposilex ME into a container holding 280 g of water and mix manually 
with a trowel to obtain a smooth mix with no lumps.
For dosing by volume, mix 2.5 parts Lamposilex ME with 1 part water. Given Lamposilex ME’s fast 
setting time prepare only enough of the product for use within one minute
Application of the mix
 • Stopping water leaks
Mold Lamposilex ME manually into the shape of a cork, wait a few seconds until mix begins to cure, 
then force product into crack or hole. Keep under pressure for 2-3 minutes until set. After this, 
remove any excess material with a sandpaper disk or abrasive wheel. With multiple leakages, begin 
applying Lamposilex ME from the top. 
• Waterproof sealing of rigid joints 
Work Lamposilex ME mix into cavity with trowel or float immediately after preparation. Keep the 
surface damp for the first 15- 20 minutes. 
PRECAUTIONS TO BE TAKEN DURING PREPARATION AND APPLICATION
· No special precautions need to be taken when the temperature is approx. +20°C. In warm weather 
do not expose material to sunlight and use very cold water for preparing the mix.
· In low temperatures, the water should be around +20°C and the material should be stored in 
heated rooms because the beginning of setting and curing is delayed at low temperatures.
