Description:-
Waterproofing admixtures can prevent water passage and protect the structures from degradation. It increases durability & helps to reduce maintenance costs. Various admixtures are helpful for structures like walls, basements, terraces & roofs. Waterproofing Admixtures have a massive range of construction.

Application and Activity

• Roof slabs – flat or sloping, chajjas, folded plate roofs, vaulted roofs, domes, etc.
• Flooring, external walls
• Sunk and non-sunk portions of bathrooms, toilets, balconies, etc.
• Overhead or underground water tanks and other large reservoirs
• Mortars for filling joints of C.I. or any other drainage pipes
• As a protective coating to RCC floorings, substructures against sulphate attacks

Features and Benifits

• It can be easily mixed with cement forming an impermeable co-matrix film
• Alkaline and compatible with concrete
• It does not facilitate carbonation
• It can be applied in moist and damp conditions, e.g., exteriors, and terraces in wet spells of monsoon
• It can be applied in underground and/or overhead water tanks almost immediately after emptying
• High flexural strength and extraordinary adhesion of the polymer
• It can be used as a base waterproofing coat on external walls, and after curing, it can receive SUNEXT
• User Guidelines
• Surface preparation of the surface to be waterproofing is very important.
• Scrub and clean the surface
• Remove laitance, dirt, paint, loose flakes, particles, foreign matter, etc.,
• For cleaning, you can use a vacuum cleaner, a high-pressure water jet, wet sandblasting, or wire brushing
• Ensure that the concrete surface possesses an open pore surface texture
• Repair any faulty concrete in the form of cracks, honeycombing, etc.
• Fill hairline cracks on plaster/mortar fill the same with POLYFILL AR as per specifications
• Remove all curing compounds and sealers
• Moisten the surface with a water jet 24 hours before applying POLYALK WP
• Mix 1 part of POLYALK WP and 1 or 1.25 parts of fresh white or grey cement
• Continuous hand-mixing to form a lump-free consistency may also be adequate
• Keep the mix continuously stirred
• Apply the slurry by brush/roller to the damp surface
• Apply two/three more coats of similar slurry at 24 hrs intervals
• Allow setting for 24-48 hours
• Cure the coating for 2-3 days by sprinkling water on the vertical surface (external walls) three times a day
• Use moist gunny bags on the horizontal surface (terraces, toilets, etc.)
• Provide a protective screed/plaster for flat surfaces on the POLYALK WP coating
• For external surfaces, provide a protective coating of SUNEXT 8.
