SN-PROTECT 2K

SN-PROTECT 2K is a premium acrylic-cementitious, polymer-modified elastomeric waterproofing and protective coating. Formulated with high-quality Portland cement, carefully graded aggregates, performance additives, and an advanced acrylic emulsion polymer binder, it delivers durable waterproofing and long-term protection for concrete and masonry substrates.

• Compliance for use in drinking water reservoirs/tanks (potability test reference as stated in the data sheet).
• Surface Spread of Flame test: BS 476: Pt. 7:71 (Class 1).
• CFTRI certified as a “potable water safe” coating for waterproofing for water tanks.

Designed as an effective waterproofing membrane on a variety of substrates. Applications include:

• Internal waterproofing of water tanks, sumps, reservoirs, planter boxes prior to tiling/final finishes.
• Sandwich waterproofing systems for terraces, balconies, kitchens, toilets to prevent water ingress.
• Protective treatment of bridge and flyover decks beneath the wearing course to safeguard concrete from rainwater penetration.

• Elastomeric: flexible coating accommodates cracks up to 2 mm with elasticity 40–50%.
• Low water permeability: excellent resistance to ingress of water.
• Adhesion: excellent adhesion to concrete and masonry surfaces.
• Eco-friendly: non-toxic with low VOC content.
• Potable-water safe: certified for waterproofing water tanks.

Correct substrate preparation is critical for optimum performance.

• Surface must be structurally sound, clean, and free from loose particles, oil, grease, or contaminants.
• Remove cement laitance, mold release agents, curing membranes, etc. by wet grit blasting or high-pressure water jetting (~150 bar), or other effective methods.
• Fill irregularities (blowholes, honeycombs) using suitable repair mortars to achieve a smooth, level surface.
• Saturate the prepared substrate with clean water before applying SN-PROTECT 2K.

Mechanical mixing is necessary. Use a slow speed (~600 rpm) heavy-duty drill with a wing-type paddle.

1. Place approximately 75% of Part A into a clean pail.
2. Keeping the mixer running, add Part B slowly.
3. Mix for at least 3 minutes to obtain a lump-free homogeneous mix.
4. While continuing to mix, add the remaining Part A (for horizontal surfaces), or only part of it (for vertical surfaces) until required consistency is achieved.

• Protect the application area from direct sunlight and strong airflow.
• Ensure controlled curing and prevent premature drying of the coating.

Slow drying ensures homogeneous curing and high waterproofing characteristics.

• Protect SN-PROTECT 2K against rapid drying due to high temperatures or wind.
• Curing by wet burlap, polyethylene sheet, or a curing compound (e.g., MASTERKURE 181) is recommended.

SN-PROTECT 2K can be kept for 12 months from date of manufacture if stored in tightly sealed original packaging, in a dry and cool enclosed area.

• Clean tools and equipment with water before the waterproofing coating hardens.
• For detailed Health, Safety and Environmental recommendations, consult the product Material Safety Data Sheet (MSDS/SDS).
