DRYKOTEC 7700 PRO
18 kg

Product Preparation

Add the entire component B (liquid) into a clean container. Using a mixer with a propeller, start mixing while gradually adding component A (powder – special cement).

Mix components A and B mechanically for an average of 5 minutes with a clean, suitable rod until a homogeneous, lump-free paste is formed.

Application

Before starting the application of DRYKOTEC 7700 PRO, moisten the surface without creating puddles or runoff. Depending on the ambient temperature, you may need to constantly moisten the surface before applying DRYKOTEC 7700 PRO.

Use a soft-bristle broom, brush, paintbrush, or rectangular brush for application.

With the substrate moist, apply the product in cross coats, in uniform and thin layers, respecting the interval between coats (4 to 8 hours) until the recommended consumption of 3 to 4 kg/m² is reached.

After applying the first coat of DRYKOTEC 7700 PRO, we recommend reinforcing corners, drains, and pipes with DRYKO TELA. Apply subsequent coats until the recommended consumption is reached, ensuring the DRYKO TELA is fully covered.

Stir the product every 15 minutes during application to prevent the solids from settling.

Leak Test

Allow the product to cure after applying the final coat before performing the leak test for a minimum duration of 72 hours.

Mechanical Protection

When necessary, we recommend applying mechanical protection using a 1:3 mix with DRYKOFIX CHAPISCO in the mixing water, with a minimum thickness of 2 cm, or laying ceramic tiles over the product with ACIII mortar.

In the last coat of the still-wet product, you can sprinkle dry sand for better adhesion of the mechanical protection or ceramic tile installation.

Recommendations

• Follow the scope, details, and finishes as per the project.
• In temperatures near or above 30°C, moisten the base more frequently and intensively; the same applies to very large areas due to the higher evaporation rate of water.
• Do not apply on a dry substrate under any circumstances. Also, moisten the product between coats.
• Not recommended for outdoor areas with sun exposure.
• On hot days, hydrate the product with water during curing. DRYKOTEC 7700 PRO does not have UV resistance.
• Each coat of DRYKOTEC 7700 PRO consumes approximately 1 to 1.5 kg/m².
• Do not install heavy coverings, natural stones, or coverings with dry joints or spacing less than 3 mm.
• Mechanical protection mortar is recommended for floors in water reservoirs due to cleaning activities in these areas.
• When installing the final covering over the waterproofing, use ACIII adhesive mortar.
• Do not use in areas with a pH lower than 6.
• For reservoir ceilings, use DRYKOPUR TANQUE, 1 kg/m².
• In reservoirs or tanks, measure the pH before human or animal consumption.
• For fish tanks and similar, measure the pH of the water and adjust if necessary before adding the fish.
• In tanks, reservoirs, and any other areas in permanent contact with water, clean the product surface thoroughly to remove product residues and rinse abundantly, avoiding chemical and mechanical aggressors.
• We recommend that our products be applied by trained professionals specialized in waterproofing activities.

Valid for 12 months from the date of manufacture if storage guidelines are followed.

Store in a covered, dry, and ventilated area, away from heat sources, in environments with temperatures not exceeding 30°C, and in an upright position.

• Handle with care. Use gloves and PPE according to current standards. In enclosed spaces, create forced ventilation if necessary.
• For more information on handling and safety, refer to the product’s Safety Data Sheet (SDS), available on our website – www.dryko.com.br.
