CERA POLY CRACKFILLER is a specially formulated non-shrink polymeric cementitious material reinforced with selected micro fibers to be used for filling cracks in concrete, masonry and plaster surfaces.

Advantages:

Excellent crack filling ability
Non-shrink and flexible
Resists further crack growth
Patches shrinkage cracks in plaster
Can be stained or over coated

Function:

The Polymer modified cementitious system, by virtue of its polymeric reaction as well as cement hydration produces a strong and dense system, which performs well in tension than conventional cement-sand mortar. Thus, the cracking tendency is further reduced.

Uses:

Cera Poly Crackfiller fills cracks in masonry, concrete and plaster.
Cera Poly Crackfiller can be used as an external rendering coat to even out surfaces.
Cera Poly Crackfiller gives a clean appearance to cracked surfaces.
Cera Poly Crackfiller minimizes further risk of cracking.

Method Of Use:

Develop the cracks to 6mm deep V - grooves. Clean grooves using wire brush and sprinkle water. Mix 3-4 parts of crackfiller with one part of water to obtain a consistent paste. Apply with a suitable putty blade. After this has set, polishing with emery paper is recommended. For renders, apply the paste to around 3mm thickness.

Coverage:

40 Rm / Kg to fill a V - groove of 6mm depth. 3 Sq.ft. / Kg for 3mm thick render.

Cera Polymortar is a single component cement based polymer modified micro fiber enriched material used for renovating old structures and repairing new construction projects. It’s a multipurpose patching and repairing mortar which can be applied on vertical and horizontal surfaces.

Advantages:

Single component and easy to use.
Provides a smooth surface finish.
Excellent adhesion to most surfaces.
Suitable for horizontal and vertical application.
Non-shrinking.
Extended working time up to minutes

Method Of Application:

Surface Preparation
The adhesion of Cera Polymortar is greatly impaired if the surface is not prepared thoroughly. The surfaces must be dry and free from moisture, dust, oil, loose particles and laitance in order to achieve maximum benefit out of Cera Polymortar

Mixing:

Depending on the consistency desired, add 8 – 9 liters of clean water per 50 kg bag of Cera Polymortar. The powder should be slowly added to the water and mixed until a homogeneous, lump- free mortar is obtained. Mechanical mixing at low speeds (300- 400 RPM) is recommended for best results. Do not over mix or add water more than recommended.

Placing:

Before application of Cera Polymortar, the surface shall be made damp and after removing excess water a bonding coat of Cera
Latex SBR or Cerabond EP shall be applied depending on the type of the repair. The mixed material shall be poured on to the surface and finished using gloved hand or mason’s tools. When repairing an RCC structure, if the reinforcement is corroded the same shall be replaced or protected by using Cera Zinc ZR.
Cera Polymortar in single layer can be applied from 5 – 15 mm thickness. If the thickness of repair is more than 15mm the same shall be done in layers allowing sufficient time between each layer. Proper keying shall be provided by roughing the surface before it sets. For horizontal surfaces, up to 50mm can be built up at one go.

Limitations:

Do not use if substrate temperature is below 7°C or if rain or freezing conditions are expected in the proceeding 24 hours after application. Do not over water; excessive amounts of water will weaken the material and reduce its durability.

Coverage:

Coverage rate is dependent on the width and depth of the area to be patched. The coverage rate is approximately 1.75 kg/sq m/mm of thickness

Curing:

Cera Polymortar is self-curing and does not require moisture curing. On extremely hot weather ensure that the water content is not evaporated by covering the repaired area with polythene sheets and wet sacks.

Cleaning:
