Sunanda Global’s Advanced Acrylic Waterproofing Systems
Acrylic waterproofing is a high-performance liquid-applied coating technology that creates durable, elastomeric membranes that protect against water ingress. They also maintain excellent flexibility to accommodate structural movements and thermal expansion. Acrylic waterproofing stands out for its superior UV resistance, breathability, and anti-fungal properties, making it ideal for exposed surfaces like roofs, external walls, and terraces. Modern acrylic waterproofing formulations offer exceptional tensile strength and long-term durability across diverse climatic conditions, ensuring cost-effective protection that extends surface lifespan and prevents water damage.

SUNKOTE WP+: High-Build Acrylic Waterproofing Coating
- All types of RCC surfaces, such as roofs, chajjas, parapet walls, external walls, sunken areas, toilets, etc.
- Can be used for flat as well as sloping roofs, existing and new
- High build, strong, thick, elastomeric, liquid-applied waterproofing membrane system
- Makes for a highly elastic & resilient coating to withstand cracks up to 2 mm as well as accommodate thermal movements
- Resistant to UV with anti-fungal properties
- Higher tensile strength, tear resistance & adhesion to substrate
- Non-toxic in nature, and the membrane allows the concrete surface to breathe
- Prepare the surface thoroughly by cleaning, washing, and removing dust, dirt, oil, grease, and loose particles.
- Damaged portions of existing roofs must be repaired with polymer-modified mortar.
- Prime the surface with POLYALK WP or SUNPRIME WP
- After the primer is cured, apply two coats of SUNKOTE WP+ with an interval of 24 hours between coats
- The second coat should be applied perpendicular to the first coat which ensures uniform masking & even application
- Allow the membrane to cure for 24-48 hours and carry out a protective screed layer with adequate slope
POLYALK WP: Polymeric Waterproofing Coating
- 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
- 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 the 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 8
- Surface preparation is significant
- 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 0.25 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-hour 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 horizontal surfaces (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
FAQs
What is acrylic waterproofing, and where is it used?
Acrylic waterproofing is an elastomeric coating applied on RCC surfaces, roof, external walls, and terraces. It forms a flexible, UV-resistant membrane that prevents water penetration while allowing concrete to breathe naturally.
How does acrylic waterproofing differ from other waterproofing methods?
Unlike cement-based coatings, acrylic waterproofing offers superior elasticity. It provides better UV resistance than polyurethane systems and maintains flexibility in extreme temperatures without requiring cement mixing.
Can acrylic waterproofing be applied to sloping roofs?
Yes, acrylic waterproofing works excellently on both flat and sloping roofs. Its high-build formulation adheres strongly to inclined surfaces, providing seamless protection without sagging or running during application and curing.
Is acrylic waterproofing safe for potable water tanks?
Yes, non-toxic acrylic waterproofing formulations are safer for water tanks. After proper curing, the membrane becomes inert and doesn’t leach chemicals, making it suitable for overhead and underground water storage structures.
