Polyurethane Waterproofing

Polyurethane Waterproofing – Application Tips

The surface to be coated should be cleaned by mechanical wire brushing / abrasive blasting equipment, followed by vacuum cleaning, to ensure it is free of loose particle, surface contaminants such as dust, laitance, curing compound, etc., detrimental to bond of coating.

Cracks in concrete if any, shall be sealed with prepacked, polymer modified Cementitious mortar and allowed to dry completely.

Application of PU coating system shall be done by roller, squeegee or airless spray equipment.

Polyurethane Waterproofing – Application Tips

Mixing: Single component system shall be stirred well before application and two component system should be mixed (Part A & B) using a slow speed heavy duty drilling machine fitted with mixing paddle until a homogenous mix is obtained (approx 3 minutes)

Application: Required thickness of coating can be achieved by one or two coats and care should be exercised a uniform continuous coat is done. For two coat application, each coat should be perpendicular to each other and one after another dries up completely. For recoating 10 to 14 hours curing time to be given (Depending on atmospheric temperature)

Thickness on vertical surfaces shall be achieved by multiple pass.

Acrylic Waterproofing – Application Tips

The surface to be coated should be clean, free of loose particle, surface contaminants such as dust, laitance, oil, curing compound, etc., detrimental for bonding of acrylic coating.

Prior to application, ensure that all surfaces are dry.

Application shall be done by roller or airless spray equipment.

The single component shall be fixed and applied over the prepared surface @ two coats, one after another dries up completely. Curing time between recoats Min 4 hours.

At right angle bends, the coating shall be carried over to the top face.

The second application shall be perpendicular to the first coat

Cementitious Waterproofing – Application Tips

The surface to be coated should be clean, free of loose particle, surface contaminants such as dust, laitance, oil, curing compound, etc., detrimental for bonding of Cementitious coating.

Spalled and deeply disintegrated concrete, if any should be removed to sound concrete and reinstated with CMCI repair mortar.

All surfaces to be coated shall be pre-wetted with clean water.

Cementitious Waterproofing – Application Tips

The liquid component shall be pored into a larger container (25 Lt capacity) and the powder component shall be mixed with the liquid component using slow speed heavy duty drill fitted with paddle. Care should be exercised to mix gradually the powder component to the liquid to avoid lump formation and mix for 3 to 5 minutes.

The mixed material shall be applied using a brush / roller @ 1mm wft per coat and a minimum of two coats is recommended

Coating should be applied one after another dries up completely and at right angle to each other. Curing time between recoats 4 to 5 hours.

Grouts Grouts are specially designed for load

transfer. They are classified based on the base material and CMCI range included cementitious, epoxy and polyester resin grouts

Cementitious grouts are designed for static and light dynamic loading and epoxy grouts are designed for high dynamic loading, impact and chemical resistance. Selection / Comparison of grouts is mainly based on strength aspects.

Sealants Joint sealants are used to seal joints and openings

(gaps) between two or more substrates

Main purposes: To prevent air, water and other environmental elements from entering or exiting a structure while permitting limited movement of substrates

Common sealants: Silicone, Acrylic, Polyurethane, Epoxies – available in single pack and two component packs

Non sag (Gun Grade) and pouring grades (PG) available

High performance sealant used in industrial applications

Chemical resistance

Good performance in submerged applications

Require a primer on almost all substrates

Sealant

Polysulfide

Polyurethane Used in industrial and commercial applications

Not used in structural glazing applications (avoid direct contact to glass)

Excellent adhesion, generally without a primer for many substrates (cementitious substrates requires a primer)

Sealants

Cemtec 30A

Single component moisture curing PU sealant, is user and environmental friendly and its superior property makes it suitable for precast concrete panel joints, bridge culverts, retaining wall joints, caulking of doors and window frames edges. The adhesion, tensile peel strength makes it practically suit for sealing / caulking of any substrate of concrete, wood, aluminum and PVC.

Fast curing property of Cemtec 30 A enables paintability after full cure. Apart from this the excellent chemical and micro organism resistance characteristics and wide temperature sustainability makes it potent for use at difficult environment.

Polyurethane Sealant

Surface (sides of joint) shall be thoroughly cleaned to ensure the same is free of dust, loose particles, laitance, rust scale and any oily substance etc.

Surface should be dry before application of the sealant.

Install joint filler to achieve correct joint depth and shape

Use sealant gun to apply the sealant for Cemtec 30 A and Gun grade sealants

Two component sealant should be mixed using heavy duty slow speed, hand held mixing machine fitted with suitable paddle, until a homogenous mix is obtained and poured directly in to the joint in case of PG and placed with sealant gun in case of GG

Sealants – Application Tips

Once the joint is filled with sealant, immediately it should be firmly flush with a tool to ensure good contact between the sealant and the substrates

Tool exposed sealant surfaces to give slightly concave shape

Remove excess compound promptly as work progresses and on completion

Masking tape should be used to have a neat finish

Sealants – Application Tips
