Hychem Deckproof — Trafficable waterproof membrane

HYCHEM DECKPROOF is also available in a spray applied version, known as DECKPROOF SP. Prior to application of HYCHEM

DECKPROOF, concrete surfaces need to be sealed with HYCRYL 101 premier. Asphalt surfaces can simply be primed with a coat of HYCHEM DECKPROOF. Metal and ceramic surfaces are primed with Primer CM.

Exposed HYCHEM DECKPROOF surfaces need to be UV protected by coating with HYCRYL Solar. A further coat of HYCRYL 304 can be applied to seal in broadcast alumina antislip aggregate.

The specific recommendation for each HYCHEM DECKPROOF waterproofing system will vary with the actual environmental and traffic conditions it is expected to cater for. Areas exposed to heavy traffic and with widespread moving cracks will need to be specified with a higher level of topping thickness.

The following 2 specifications provide an outline for light and heavy traffic conditions. Many other variations can be considered.

eg. antislip aggregate would not be required under stadium seating.

• A. Light Duty – Minimum 1.5mm Topping Depth
• Step 1 Repair all cracks in excess of 500 microns with HYFLEX NS

litre and broadcast suitable alumina antiskid aggregate

• meters a litre to seal in Antiskid
• B. Heavy Duty – Minimum 3mm Topping Depth

PA at 1.4 l/sqm

Step 5 Broadcast suitable antislip aggregate into the wet HYCHEM DECKPROOF (4 kg/sqm)

Step 6 Apply a coat of HYCRYL Solar to seal in antislip (3-4 sqm/ltr)

The product is used in combination with HYCYRL Solar and HYCRYL 304 to produce an exposure and UV resistant water-proof membrane system which is capable of withstanding foot and vehicular traffic.

Resistance

HYCHEM DECKPROOF is a flexible, crack bridging membrane suited to a wide variety of waterproofing applications.

The product is used in combination with HYCYRL Solar and HYCRYL 304 to produce an exposure and UV resistant waterproof membrane system which is capable of withstanding foot and vehicular traffic.

HYCHEM DECKPROOF based membrane systems are suitable and recommended for:

• The waterproofing of pedestrian and vehicular traffic areas such as roofops, balconies and carparks.
• The protection and waterproofing of stadium terracing.
• The waterproofing of containment structures such as reservoirs and bunded material storage areas.
• The waterproofing of bridge desks prior to asphalt resurfacing.
• The waterproofing of turnells, channels and dams.
• Protection and waterproofing of offshore platforms.

HYCHEM DECKPROOF is also available in a spray applied version, known as DECKPROOF SP. Prior to application of HYCHEM DECKPROOF, concrete surfaces need to be sealed with HYCRYL 101 premier. Asphalt surfaces can simply be primed with a coat of HYCHEM DECKPROOF. Metal & ceramic surfaces are primed with Primer CM.

Exposed HYCHEM DECKPROOF surfaces need to be UV protected by coating with HYCRYL Solar. A further coat of HYCRYL 304 can be applied to seal in broadcast alumina antislip aggregate.

HYCHEM DECKPROOF is a methacrylate modified Polyurethane membrane. This provides the excellent crack bridging characteristics of Polyurethane with the rapid cure and good inter-layer bonding of methacrylate resins.

The methacrylate cure system also allows the membrane to be applied at temperatures down to -10 degree.

The applied membrane has excellent waterproofing properties, withstands stress and substrate movement and is highly impact and puncture resistant.

Once applied, it is fully cured within 1 hour of application and ready for traffic. Damaged sections can easily be repaired with further toppings of membrane even after many months.

Key Benefits

HYCHEM DECKPROOF is resistant to grease, mineral oils, salt solutions and dilute mineral acids. For other containment chemicals please contact the HYCHEM Technical Department.

The specific recommendation for each HYCHEM DECKPROOF waterproofing system will vary with the actual environmental and traffic conditions it is expected to cater for. Areas exposed to heavy traffic and with widespread moving cracks will need to be specified with a higher level of topping thickness.

Chemical

All Substrates must be dry, firm and free of dust, fat and oil.

Conventional methods of surface preparation such as degreasing, scarifying and grinding are suitable.

The HYCRYL 101 needs to be thoroughly stirred prior to adding thebenzoyl peroxide catalyst. The weight of peroxide to be added is dependent on temperature:

• 1% at 30°C
• 2% at 20°C
• 4% at 10°C
• 6% at 0°C

The primer is applied with a shortnap roller. Quartz sand is sprinkled into the wet primer to aid adhesion. (0.3 kg/sqm).

Membrane Application

Mix the liquid membrane before use, to disperse all ingredients.

Catalyst is then added to the liquid with the quantity varying with temperature. Each 30kg kit of membrane requires catalyst as follows:

• 200g at 30°C
• 350g at 20°C
• 700g at 10°C
• 1200g at 0°C

For temperatures below zero, a special accelerator needs to be added.

Topcoat Application

Apply HYCRYL Solar with a squeegee and/or paint roller at a minimum coating thickness of 3 sqm/l. This product may also be applied at a higher coating depth up to 0.8 l/sqm.

Add catalyst to liquid according to environmental temperatures:

• at 30°C 80g or 120ml per 10 Litre of HYCRYL Solar
• at 20°C 100g or 150ml per 10 Litre of HYCRYL Solar
• at 10°C 200g or 300ml per 10 Litre of HYCRYL Solar
• at 0°C 300g or 450ml per 10 Litre of HYCRYL Solar
• at -10 C 500g or 750ml per 10 Litre of HYCRYL Solar

NOTE: Antislip and Antiwear Aggregate can be added to the HYCYRL Solar as required.
