METHOD OF APPLICATION IN WATER PROOFING :
SURFACE PREPARATION:
- Prior to application of BULWARK LEAK BOND the surface must be prepared as mentioned below to avoid failure and to achieve maximum beneficial properties.
- When placing BULWARK LEAK BOND coating, water should be removed so that surface is only damp. In no case there should be standing water.
- The surface shall be cleaned to remove all dust, foreign matters, loose materials or any deposits of contamination which could affect the bond between the surface and the “BULWARK LEAK BOND” coating.
- In sunken corner area must to be packed with Bulwark cement Mortar prior to this application.
- All concrete surfaces shall be thoroughly pre-wetted prior to the application of “BULWARK LEAK BOND” coating by sprinkle water on flat surface.
APPLICATION:
- BULWARK LEAK BOND must be mixed with in the ratio of 1:1:5.75 (PART A: WATER: PART B)
- The mix has to be stirred thoroughly until smooth homogeneous slurry is obtained. Wait for 1-2 minutes to release entrapped air bubbles.
- Any lump found in the mix should be removed or mixed thoroughly.
- Two are recommended one more coat can be done to achieve desired thickness.
- First coat should be allowed to air dry for 3-4 hours prior to apply subsequent coat.
PRECAUTIONS:
- BULWARK LEAK BOND system must be applied with temperature above 5⁰ C and below 40⁰ C.
- Mix Part A and Water then slowly add Part B use slow speed stirrer to mix thoroughly. and use slow speed stirrer to mix thoroughly.
- Use Bulwark Leak Bond-2 when expectation is high flexibility with high water resistance.
STORAGE:
- Store in dry cool place in the temperature range from 5⁰C to 30⁰C in sealed condition.
- Do not allow to freeze. Keep away from direct sunlight.
