Hulk WP® (Liquid Waterproofing Membrane) by Hulk Systems Inc.
Cold applied, sprayable polymer membrane with both elastomeric and water-resistant attributes. Extremely durable and maintains performance in a wide spectrum of temperatures. Key component for use on all applications and systems.
Application
Hulk WP® is ideally tailored for vertical waterproofing applications below grade, and above grade as a liquid applied vapor barrier.
Typical installation for vertical applications on concrete is 45 mil WFT. For magnesium or foam surfaces recommended thickness is 35 mil WFT basecoat with Hulk SRT® immersed throughout, followed by a 35 mil WFT topcoat.
Always contact your local Hulk Systems Inc. representative to discuss specific project requirements. To promote proper permeability and performance, when applying vertically, Hulk WP® needs to be applied in 35 mils coats to be able to build up to your required thickness, with a minimum recommended dry time of 2 hours between coats.
Available in 4 color options:
- Brand Exclusive Green
- Industry Black
- Solar Reflective White
- Concrete Grey
Mixing
- Ensure material has been stored between 40° – 70° F (4° – 21° C) and has not been allowed to freeze.
- Mix thoroughly for a minimum of 1 minute using a mechanical mixer at slow speed to ensure a homogeneous material. If air bubbles occur due to excessive mixing speeds, allow product to settle for a minimum of 10 minutes before use.
Vertical Application
- Apply waterproofing membrane system in accordance with manufacturer’s instructions.
- Treatment of Through Wall Joints & Penetrations
- Thoroughly pack all through-wall openings and penetrations like exposed shoring piles, ties-backs, and other anchors with detailing mastic.
- Thoroughly pack all through-wall openings and penetrations like exposed shoring piles, ties-backs, and other anchors with detailing mastic.
- Treatment of Existing Cracks and All Non-Structural Joints
- Identify and install detailing mastic in all cracks and all non-structural joints prior to first coat.
- Identify and install detailing mastic in all cracks and all non-structural joints prior to first coat.
- Treatment of Inside & Outside Corners
- Install detailing mastic to create a minimum ¾” (25.4 mm) fillet in all inside corners prior to first coat.
- Install detailing mastic to create a minimum ¾” (25.4 mm) fillet in all inside corners prior to first coat.
- Apply membrane by sprayer or roller, at a minimum coverage rate of 66 ft.2/U.S. gal (1.62 m2/L), providing a thickness of 40 wet mils.
- OPTIONAL STEP: For Most Concrete Surfaces | MANDATORY STEP: For Blindside Applications, High Water Table Applications, ICF, Wood and Magnesium Board Surfaces if no extruded protection board or drainage screen is specified.
- Fully embed the reinforcing fabric, Hulk SRT® into this first coat.
- Fully embed the reinforcing fabric, Hulk SRT® into this first coat.
- On applications where textile has been embedded into coating, immediately apply the second coat of membrane by sprayer or roller, at a minimum coverage rate of 75 ft.2/U.S. gal (1.84 m2/L), providing a thickness of 30 wet mils.
Roller Application Recommendations
Using a heavy nap roller will allow for better coverage and an overall thicker coat. 1.25” – 1.5” nap size or greater is recommended to achieve the proper mil thickness with less coats.
Spray Application Recommendations
For airless sprayer applications, Hulk Systems® recommends applicators use a tip orifice size of no less than 0.021” with a 10” – 12” fan spread. Example: 521 tip or greater. A minimum requirement of the pump or equipment would be a maximum working pressure of no less than 3300 psi, as well as an equipment specification that allows for materials to be sprayed with a viscosity of 20,000 PS @ 6RPM. Hulk Systems® recommends both Graco and Titan airless equipment. For recommendations on specific brands, models, or larger commercial pumps, please contact Hulk Systems®.
Cold Weather Applications of Hulk WP®
- Always ensure your equipment is suitable for cold weather applications. Be aware that product freezing inside lines, pumps, guns, hoses, etc. can and likely will cause damages. Take all precautions necessary including contacting your equipment provider / brand rep to find out how best to winterize your equipment before cold weather use.
- When applying in temperatures ranging from 32o F (0o C) – 25o F (-4o C) applicator must ensure that they never allow material to freeze in container or pump during application. Keep stored material and equipment properly heated and always insulated when working in below freezing conditions. It’s recommended by the manufacturer, that when performing cold weather applications, to condition all material to 60º – 85º F (16º – 29º C) for 24 hours prior to use.
- Use an anti-freezing lubricant for your airless paint sprayers lines and hoses. You use it after cleaning your airless to help prevent any corrosion during storage. It will prevent freezing and help extend the life of your pump.
- When applying in temperatures ranging from 25o F (-4o C) – 10o F (-12o C) applicator must use a material heat exchanger and heated insulated equipment lines.
- Never apply material below 10o F (-12o C).
- Do not apply membrane if rainfall or heavy snowfall is forecast or imminent within 12 hours.
- Do not apply waterproofing membrane to any surfaces containing frost.
- It is recommended to heat the substrate surface by torch (if concrete) when possible.
- Hoarding and heating the application area is always the recommended and preferred method of installation.
- Cold weather applications are performed at the risk of the installer and client. Hulk Systems Inc. will not be held liable for any failures or equipment damages that may result from either the product(s), improper application, or improperly used or failed equipment in temperatures below freeze point due the nature of water-borne materials.
