Mycro-empu Cia630 Waterproofing Chemical For Industrial

MYCRO-EMPU CIA630 is a single-component, liquid applied, elastomeric polyurethane coating for waterproofing of concrete surfaces. MYCRO-EMPU provides excellent resistance to moisture, water, and salts penetration into concrete and masonry surfaces.

Uses:MYCRO-EMPU is used to protect and prevent water leakage and penetration of moisture into the Concrete and other masonry surfaces.

MYCRO-EMPU is ideal for:

• Waterproofing of Podiums, Sunken Slabs, Terraces.

• MYCRO-EMPU has the ability to uniformly and completely cover the surface, forming a continuous membrane

Features and Benefits

• Liquid applied membrane, can be applied with roller, brush or spray.

• Non-toxic, Provides a seamless coating.

• Flexible, has crack bridging ability.

• High bond strength to a variety of substrates and building materials.

• Resists positive water pressure.

• Resistant to chemicals.

• Excellent resistance to humidity and temperature.

• Excellent resistance to Chlorides and Alkalies.

• Very high tensile strength.

• UV stable.

Application Methodology

Step 1: Surface Preparation

Surface need to be cleaned by wire brushing followed by vacuum cleaning so that surface is free of any loose particles, dust, laitance, mould release agents and curing compounds. Water jetting is not recommended. All cracks to be treated with MYCROSEAL – EXT modified mortar. Surface is allowed to self-cure for 24 hours. Ensure the moisture content of the surface is below 5% before Priming.

Step 2: Fillet preparation

Horizontal and vertical angle joints need to be prepared with 50x50mmconcave fillet using concrete admixed with MYCROPROOF – AW+@ 250 g/50 Kg bag of cement. Fillet should be cured to gain strength and completely dry before Primer application.

Pipe penetration sealing: Clean around Pipe penetrations and seal the junction with low viscous solvent free MYCRO0-EPOFILLER admixed with Silica sand.

Step 3: Priming

PU based MYCROPAC PRIME; a polyurethane-acrylic-based primer combines is recommended before application of MYCRO-EMPU CIA630. Mix both the components of Primer and apply by brush on cleaned concrete. Pot life of the mixed primer is only 30minutes.Allow the primer to dry for 4-5 hours.

Step 4: Product Application

Prior to application, thoroughly mix the contents of the container using a slow speed stirrer at 300 rpm. Care should be taken to scrape the sides and bottom of the container with the mixer. Do not add solvent, thinners, water at any time. After mixing, immediately apply MYCRO-EMPU over the tacky primer while ensuring a continuous coating of uniform thickness. A Lambswool roller is recommended for such application. A brush may be used for touch-up and edging work or for areas unsuitable for roller application.

MYCRO-EM must be applied all along the angle fillets, corners, joints around the pipes, conduits etc. Apply MYCRO-EMPU on surrounding walls up to a height of minimum 300mm from FFL. Always apply in two coats in order to avoid pinholes. The second coat can be applied after the first coat has dried (12-16 hours@ 25⁰C) depending on the ambient and surface temperature. To ensure mechanical bonding for protection plaster, granded sand should be sprinkled while coating is tacky.

Step 5: Protection with Screed

Prior to laying of protection screed, use a separation barrier of 160 gsm Geo Textile. >50 mm Screed to be applied as per slope requirement. For vertical application 15-20 mm plaster is recommended.

Coverage: 2 Kg/m² for 1.43 mm WFT or 1mm Dry Film Thickness (DFT).
