Cement based infiltration crystalline type waterproofingcoating

（Permanent and environmental protection waterproof）

Products Code:       L***8

Products Standard: CCCWＣＩ (Ⅱ)GB *********1

Products model: I（Ⅱ）

Introduction：

L***8 is efficient and environment-friendly coating fabricated by mixture of imported capillary crystalline master batch, high-performance additives, high-strength cement, and gradingquartz sand. Active substances rich in such product can dissolve in water and infiltrate theconcrete. After reacting with unhydration cement, such active substances become stiff and water-fast crystals, filling into pores and cracks of concrete, which improve the density and waterproofness of the structure. Remarkably, waterproofness works perennial in dry-and-wet cyclic process.

Features:

1. Wide range of application

2. Non-toxic, environment-friendly andgas-permeable

3. Remarkable thermo stability andfreeze-thaw resistance, good resistance of contraction and crack.

4. Second process ofanti-permeability resulting from capillary crystalline regeneration.

5. Coating layer strong enough for subsequent construction without any protection layer.

6. Chemical resistance

Range of application:

1. Large-scale concrete structure such as basements, air defense projects, water towers and reservoirs, as well as waterproof and moisture resistance for concrete roof of residents housing.

Construction tips:

{C}1.     Base treatment

(1) Ensure the base being no water, dust and pollutant, strong, smooth and clean withoutstructure defect. Propercompressive strength and flexural strength are required.

(2) Pits, holes, and cracks over 0.5mm long on the base should be filled and outthrust must be wiped out.

(3) Internal corners, external corners and complex node parts should be treated into arc angles.

(4) Bases are required to be humid but ponding-free before construction.

{C}2.     {C}Method of application

(1) Pour *5kg L***8 powders into water (plaster method: 5.5L; brushing method: *0L) slowly under stirring (**0W, ******0rpm) until the the lump of solid in themixture disappear, then stop stirring for *0min and stir once again before application. The mixture obtained should be used within 1 hour.

(2) Two or more layers of coating is required,each of whichshould be brushed in perpendicular direction to previous layerandconstructed after previous layer is dry and solidified.High pressure spraying method is also available in construction processes.

(3) Coating constructed in summer needsmoist maintenance **5 times after *2 hours. Better maintenance by covering humid cloth or straw bags is also suggested if affordable.

Notes:

{C}1.     Mechanical stirring is needed to ensure well stirring.

{C}2.     Stirring twice contributes to curing, uniformity, eliminating air bubble.

3.  The amount of water should not be excessive for retaining property of coating.

4.  Palm fibre or wool brushes are suggested.

5.  Sun exposure in summer or construction below 5oC should be prevented.

Reference dosage

Reference dosage is **1.2kg per square meter. (brush two layers)

Environmental protection measures

Expired product after inspection qualified can be normal use, if unqualified Scrap disposal should be done. Scrap products should comply with local laws and regulations, no optionally dumping.

Health and safety

Storage and transportation

{C}1.     {C}Keeping away from rain washing, damaging during transportation and storing indoor, avoiding light.

{C}2.     {C}Storage life of product unsealed is one year.

Packing

Net weight:*5kg/bag; *0kg/barrel
