 For best performance

HLM 5000

• Apply HLM 5000 when substrates are dry and air temperatures are between 4°C and 32°C; for application at temperatures below 4°C, consult MBT's Technical Services.
• Avoid application when inclement weather is present or imminent.
• Do not apply to reinforcing bars or to wet or contaminated surfaces.
• Protect HLM 5000 coated surfaces from puncture with protection board until required topping or backfill is placed.
• If project schedule does not permit 14-day minimum cure of concrete, contact Technical Service for primer recommendations.
• Carefully work material over irregular concrete to avoid pinholes and holidays.
• Do not apply to surfaces treated with curing and parting compounds unless they have been completely removed chemically or mechanically.
• Not intended as an exposed or wearing surface.
• Do not use where a solvent odor is objectionable, e.g., near areas where food preparation or processing take place during the application.
• Specify wet or paper curing for concrete to be coated with HLM 5000; avoid using liquid curing compounds except MASTERKURE 181.
• Before applying HLM 5000, protect all drains and drain openings.
• Cold temperatures influence viscosity and handling characteristics of HLM 5000: heat increases and cold decreases the flow. Keep HLM 5000 cool in hot weather and warm in cold weather.
• Do not directly heat containers with flame, stove, hot plate, or oven.
• Patch all voids and deep depressions in substrates with appropriate MBT patching material before applying HLM 5000.
• Apply asphalt overlay in accordance with asphalt industry and manufacturer's standards.
• The HLM 5000 membrane must be protected from heat, impact, and any other damage that could be caused by an asphalt overlay.

 Order information

HLM 5000 comes in a variety of grades for different applications.

• HLM 5000 SL (self-leveling) is formulated for application by squeegee to horizontal areas.
• HLM 5000 T (trowel) is formulated for application by trowel to vertical surfaces.
• HLM 5000 S (spray) is a specially formulated version of 5000T for spray application.
• HLM 5000 R (roller) is formulated for application by roller to vertical and some horizontal surfaces.
• Companion product to HLM 5000 is PRIMER 733, used for priming metal to be covered by HLM 5000, and SOLVENT NO. 2, used to clean tools and equipment.

 Shelf life

Shelf life of HLM 5000 is 6 months in unopened containers when stored in dry conditions between 4°C and 27°C. During storage, an easily removed skin of HLM 5000 may form, which does not affect performance of the product.

 Coverage

1.6 litres m² gives dft 1.3mm

 Note: Coverage may vary with the application technique used. Actual coverage rate and thickness depend on finish and porosity of the substrate.

 How to apply HLM 5000

 Surface preparation

For best results, all concrete deck surfaces should be lightly steel troweled to a fairly smooth finish. New concrete must be properly water cured at least 14 days. For extremely porous block, prime and coat with diluted HLM 5000.

Remove dust, dirt, and other contaminants just before or during application. Surfaces must be dry at the time of application.

Air void pockmarks or honeycombs must be opened up to allow HLM 5000 to fill the cavities completely. Air entrapment within voids may cause blisters. Extreme cases may require a parge coat.

 Prestriping: Before applying the final membrane, all joints, cracks, and openings around protrusions must be sealed by caulking or prestriping (a preliminary coating of HLM 5000 applied with a trowel or stiff bristle brush). Allow to dry overnight before applying final membrane. When the final membrane is applied, the overall thickness over joints and cracks, at coves and around penetrations should be approximately 2.5 mm on the standard system.

 Static joints and cracks:

Joints and cracks less than 1.8 mm should be filled by pre-striping. Apply material so it both fills and overlaps the joint or crack to a width of 100 mm on each side.

 Working or expansion joints:

All joints over 3mm must be sealed with a Sonolastic sealant. Any working joint less than 3mm should be routed to a minimum of 3mm and filled with a Sonolastic sealant. Prevent the waterproofing membrane from adhering to the joint sealant, which could cause sealant or membrane failure, by applying a coat of liquid household carnauba wax over the cured sealant and then prestriping.

 Metal:

All metal must be wire brushed or sandblasted to bright metal. Prime with a quality rust-inhibiting metal primer and PRIMER 733 before application of HLM 5000.

 Vent, drain pipe, and post penetrations:

Clean metal surfaces to bright metal and prime with a quality rust-inhibiting metal primer followed by PRIMER 733. Remove dust, debris, and any other contaminants from voids. Seal with the appropriate Sonolastic sealant. Openings exceeding 3mm must first be sealed with Sonolastic sealant. Next, prestripe to a minimum width of 100mm on the base slab and continue up the penetration to the height of the top course wearing surface.

 Application

 Standard system*

For horizontal applications, simply empty contents of pail and spread immediately to ensure workability. Best results are obtained by marking off 11.61 m² areas and evenly spreading the contents of a 18.93 litres unit with a rubber-edged notched squeegee. Repeat the above procedure until the entire surface is covered. The above rate gives a wet film thickness of approx. 1.6mm.

Select the grade of HLM 5000 that best meets individual job requirements. Use HLM 5000 T for trowel application, HLM 5000 S for spray application, HLM 5000 R for roller application, or HLM 5000 SL for squeegee application.

Verify the applied thickness with a wet film gauge as the work progresses.

The integrity of the cured membrane on a horizontal surface may be verified by damming the entire area and flooding with water to a minimum depth of 5mm and allowing the water to stand for 24-48 hours. Visually inspect the bottom surface, if possible to check for any water penetration. If repairs are necessary, the area should be drained and allowed to dry before reapplying HLM 5000. After re-application, the area should be tested again for membrane integrity.

 High-build system*

Apply 1.6mm wet thickness of HLM 5000, followed by setting Sonoshield Reinforcing Fabric into the wet material. Overlap all seams a minimum of 76mm.

Allow the first coat to dry overnight and follow with a second 1.6mm wet application of HLM 5000.

 Spray equipment:

For spray equipment recommendations, consult the equipment manufacturer.

 *Note: Finish coat must be applied in a pinhole-free, continuous membrane for waterproofing integrity.

 Curing

Appreciable properties develop within 24-48 hours at 24°C and 50% relative humidity. HLM 5000 should be protected from traffic before placement of protection board and topping. Install tightly butted protection board (minimum 3mm thick) as soon as possible following cure of HLM 5000.

 Clean up

Clean all tools and equipment immediately after application with CLEANING SOLVENT NO. 2.

 How to apply protection course II

 Surface preparation

Waterproofing membranes must be protected against tear, puncture, and other abuses during placement of concrete wearing slabs and reinforcing steel. They should also be protected from job-site traffic and backfilling operations.

All specifications calling for membrane waterproofing should also require protection of membrane as an integral part of the overall waterproofing system.

 Application

Install tightly butted MBT Protection Course II as soon as possible following cure of the liquid membrane. Protect HLM 5000 from traffic before placement of protection board. HLM 5000 must be cured before installation of any topping.

Where hot bituminous topping is to be applied over the 6mm thick protection board, cover the butt joints with flexible tape. Minimum topping thickness is 76mm, as recommended by the Asphalt Institute, in order to minimize crack reflection.
