BULWARK B-CRETE provides properties to combat the short comings of plain cement, particularly its poor adhesion properties, low impact strength, low flexural strength and thin section fragility. BULWARK B-CRETE polymer adds to the potential use as well as enhances the properties of cement slurry/ mortar/concrete making them excellent choice for use in new as well as renovation work.
AREA OF APPLICATION:
- BULWARK B-CRETE can be used as multi-purpose chemical to increase the waterproofing ability and strength of Plain cement concrete, Reinforced cement concrete and Cement Mortar for Plastering.
- BULWARK B-CRETE can be used as Cementitious Water proofing system and Exterior primer.
FEATURES:
- Combines a tough, flexible, hard-wearing surface with waterproofing.
- Allows trapped vapour to escape thus preventing peeling and blistering.
- Can be applied in uniform thickness to horizontal and vertical surfaces.
- Develops excellent bond to most building materials. Reduces or prevents salt penetration into concrete.
- BULWARK B-CRETE is not affected by ultraviolet light or by chemicals ranging from mild acids to strong alkalies.
- BULWARK B-CRETE is highly durable in continuous wet condition.
- BULWARK B-CRETE is non-flammable and does not give off toxic gases, when exposed to fire,
- BULWARK B-CRETE is not harmful to the health of workman.
METHOD OF APPLICATION:
Prior to application of BULWARK B-CRETE, surface must be prepared as mentioned below to avoid failure and to achieve maximum beneficial properties.
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 B-CRETE coating. This can be done by scarifying, grinding, water blasting, sand blasting, and acid washing or by any other approved method.
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.
WATERPROOFING COATING:
When placing BULWARK B-CRETE coating, water should be removed so that surface is only damp. In no case there should be standing water.
Depressions are to be filled and leveled using BULWARK B-CRETE fillers. For filler, the mixing ratio is 1 kg cement: 1.5 kg silica sand: 0.50 kg of BULWARK B-CRETE.
APPLICATION:
BULWARK B-CRETE polymer is mixed with neat fresh cement in the ratio of 1:2 by weight. The mix has to be stirred thoroughly until smooth homogeneous slurry is obtained. Wait for 5-10 minutes to release entrapped air bubbles. Any lump found in the mix should be removed or mixed thoroughly. The mix has to be applied by brush on rendered and/or prepared surface. Two or more coats are recommended. First coat should be allowed to air dry for 5-6 hours prior to apply subsequent coat.
CURING:
After application of final coat of BULWARK B-CRETE, initial air drying shall be done for 2-6 hours. During this period no water is to be used for curing. In case of high temperature and low humidity combined with high wind condition, the coating shall be covered with polythene sheet to avoid rapid drying of the TECHNICAL DATA coating.
After maximum period of 6 hours after the final application, moist curing shall be done for the next 24 hours by spraying/sprinkling of potable water on BULWARK B-CRETE COATING. During this period at no point of time should the BULWARK B-CRETE coating be left completely dry or submerged in water. Following moist curing, the BULWARK B-CRETE coating shall be allowed to air dry for 2 days before submersion in water.
PRECAUTIONS:
BULWARK B-CRETE system must be applied with temperature above 10⁰ C and below 40⁰ C. BULWARK B-CRETE should not be used without addition of cement.
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.
PACKAGING:
- 10Kg, 20kg, 200kg HDPE plastic container.
