WATERPROOFING
DESCRIPTION
KKS® ELASTSEAL 332 is a highly elastic waterproofing membrane, self-drying, water repellent polyurethane based. Application in liquid form, when hardened it forms seamless continuous film, excellent adhesion to most types of surfaces.
ADVANTAGES
• One-component, easy-to-use product that can be applied with existing tools such as roller, brushes, pressure spraying.
• Good elasticity so not be peeled, cracked, ensure waterproofing even the plaster surface inside has cross-foot crack because of thermal expansion.
• Good adhesion on a variety of surface types.
• Seamless membranes without lining.
• Alkali resistance, water resistance and weather resistance. especially for UV rays, suitable with tropical areas.
• Non-toxic, non-flammable, environmentally friendly.
• Not moldy
• High solid content, low VOC.
USES
KKS® ELASTSEAL 332 is used for surface’s waterproofing of following construction category:
• Waterproofing for the exposed concrete roof, cement tiles, terrazzo tiles.
• Waterproofing for dome, roof terrace, sunbathing balcony and balustrade wall.
• Wet areas such as waterproofing lining before placing tiles in bathrooms, kitchens.
• Waterproofing over old roofs that need to be upgraded.
APPLICATION
SURFACE PREPARATION
The concrete substrate must be hard enough (28 days) and cleaned, free from oil, grease and other contaminants. A pull-off strength of at least 1.5 N/mm2. Maximum substrate moisture content of 5%, maximum air humidity 85%. Seal surface damage such as pore, porosity... with KKS® MORTATOP to have a flat surface. At the water leakage, KKS® WATERPLUG 302 should be used to completely prevent.
Metallic surfaces such as iron, steel must be cleaned of rust.
It is recommended that all corners be chamfered with mortar so that waterproofing membranes can be swept and bonded.
APPLICATION
Normally primer is not required, but if many pore, non-flat surfaces, apply KKS® PRIMER S160 with 0.2 - 0.3 kg / m2. After application of the primer, surface should be covered with waterproofing within 24 hours to avoid contamination.
Step 1: Stir the paint barrel to get uniform color. Avoid creating air bubbles.
Step 2: Use a smooth roller, brush or spray machine to apply 2 coats. With airless spray equipment, such as Graco X45 piston pump, parameters set is: pressures 200-250 bar, nozzle 0.38-0.33 mm, spray angle 50 - 80o.
IF THE REINFORCEMENT LAYER DOES NOT IN USE:
• KKS® ELASTSEAL 332 is applied in two coats with the ratio is 0.6 - 0.9 kg/ m2/ layer
IF THE REINFORCEMENT LAYER IS USED:
• Use brush or roller application KKS® ELASTSEAL 332 as a base coat. Apply KKS® FLEXSHEET reinforcement on wet substrates, ensuring that the reinforcement layer is evenly covered and stretched flat without wrinkles. The overlap between the two coating is at least 50 mm. Constructed with a norm of 1.6 kg / m2
• Apply the second coat immediately with a norm of 0.8 kg / m2.
NOTICE
• KKS® ELASTSEAL 332 is not use at the place where standing water or continuous submerged in water or the surface moisture content increase.
• Do not work in rain conditions. If it is raining during construction, should stop to cover the area of construction being affected directly from rain water.
• Self-drying material, no watering maintenance required after application.
• Apply a second coat after the surface of first coat has dried.
CLEANNING OF TOOLS
Clean water, tools and equipment immediately after application and before the material is harden.
