Uses CX Crackplug 113 is used for sealing cracks on plaster, masonry and concrete substrates.

Advantages

• Single component easy to use
• Versatile Can be used for plaster, masonry or concrete, can be painted after application
• Non-sagging Can be used for horizontal, vertical and overhead applications
• Good adhesion Effective bonding with substrate
• Non-Shrink Shrinkage cracking eliminated

Description CX Crackplug 113 is a crack sealing cementitious material in powder form. It is easy to apply and can be finished or smoothened off with a putty blade or a damp sponge. It sets quickly on the application and can be overcoated with common paints/coatings.

Properties

• Color White
• Setting time 15 to 20 min
• Compressive strength 22 N/mm2 in 7 days
• W/p Ratio 0.36

Application instructions

• Surface Preparation The cracks to be sealed shall be saw cut or chiseled to form a V groove of approximately of 6mm x 6mm. The grooves shall be cleaned to remove all the loose particles, dust, etc. The groove shall be sprinkled with clean water before applying the sealing mortar.
• Mixing CX Crackplug113 shall be mixed with water adopting w/p ratio 0.36 by weight or a mix proportion of 1 part of water to 2.5 - 3.0 parts of RECON CS, by volume. Thorough mixing shall be carried out till a smooth, homogenous paste is obtained.
• Application The mixed paste is filled into the groove by gloved hand and the surface finished using a
• putty blade. This is continued till the full length of crack is sealed.
• Curing Curing is necessary only when groove size exceeds 6mm width or in areas exposed to UV.
• Cleaning Tools may be cleaned with clean water as CX Crackplug 113 is a cement based product.

Limitations CX Crackplug 113 crack sealer cannot be used for moving cracks and for crack width greater than 30mm.

Estimating

• Packaging CX CRACKPLUG 113 is supplied in 1kg. pack
• Coverage38 RM for a V groove crack of 6mm x 6mm. The actual coverage may vary depending on the substrate conditions

Storage

• Shelf life CX Crackplug 113 has a shelf life of 6 months in original unopened packs if stored in unopened conditions below 35 0 C.

Precaution

• Health & Safety instructions CX CRACKPLUG 113 has no health hazards in normal use. Gloves shall be worn while mixing and during application. Splashes of material to the eyes shall be washed off with clean water. In the event of prolonged irritation, medical advice shall be sought.
• Fire CX Crackplug 113 is non flammable

• Pre-packed formulation to overcome variation in site batching
• Contains no chloride admixtures

Description: CX Fastplug 112 is supplied as a ready to use the blend of dry powders which requires only the addition of clean water at the site to produce a highly consistent, rapid setting mortar which is easy to apply in many difficult conditions. The material is based on a blend of cement, graded aggregates, special fillers and chemical additives which control the rate of set and minimize the risk of thermal cracking.

Technical support: Chemax offers a comprehensive range of high performance, high-quality concrete repair and construction products. In addition, CHEMAX offers technical support service to specifiers, end users, and contractors, as well as on-site technical assistance in locations all over the country.

Design criteria: CX Fastplug 112 can be applied to the horizontal, vertical or overhead surface at a wide
range of thickness. Generally, the volume of mixed material used in a single application is restricted to
that which can be applied by trowel or gloved hand. Thicker sections can be built up in layers. If any
doubt arises about the nature of the substrate, consult the local CHEMAX office for further information.

Properties:
Initial set time: Approx. 1 - 2 mins. at 30 0 C
Note: Set times will be extended when mixed or applied at lower temperatures.
Compressive strength: 25N/mm 2 @ 28 days @ 30 0 C
Heat generation characteristics: High heat output (exotherm) leads to undesirably high shrinkage and consequent thermal cracking. The curves below show the low heat output of CX
FASTPLUG 112 which minimizes the risk of shrinkage and thermal cracking
