Dr. Fixit Pidifin 2K (112) – Acrylic Cementitious Waterproof Coating

Dr. Fixit Pidifin 2K: The Flexible, Two-Component Waterproofing Solution

For areas exposed to constant water and structural movement, such as bathrooms, terraces, and water tanks, standard coatings often fail. Dr. Fixit Pidifin 2K is a specialized, two-component (2K) acrylic polymer cementitious coating engineered to provide high flexibility and superior adhesion. This unique system forms a dense, seamless membrane that bridges hairline cracks, offering permanent protection against water ingress and efflorescence.

The 2K formula—mixing the liquid polymer with the cement-based powder—ensures a strong, durable, and flexible barrier. Dr. Fixit Pidifin 2K is the professional choice for critical damp areas where traditional waterproofing systems are prone to cracking due to thermal movement.

Why Choose Dr. Fixit Pidifin 2K?

Pidifin 2K stands out from single-component waterproofing agents:

• High Flexibility: The acrylic polymers allow the membrane to stretch and accommodate minor substrate movement and temperature changes, preventing the membrane from cracking.
• 2K Performance: Mixing the two components creates a highly dense, cross-linked structure with maximum water resistance and adhesion.
• Positive/Negative Side: Can be applied successfully on both the positive side (water source) and negative side (internal face of a wet wall).
• Excellent Adhesion: Bonds powerfully to concrete, plaster, masonry, and concrete blocks.

Key Features of Dr. Fixit Pidifin 2K

• Crack Bridging: Effectively bridges static hairline cracks up to 0.5mm, maintaining the waterproof seal.
• Non-Toxic: Safe for use in potable water tanks, ensuring the water remains contaminant-free.
• Seamless Membrane: Creates a joint-free barrier that eliminates potential points of water entry.
• Easy to Apply: Can be applied by brush or roller, making it accessible for contractors and large-area application.

Recommended Application Areas

This **two-component waterproofing** solution is ideally suited for:

• Bathrooms & Kitchens: Underneath tile finishes (wet areas) before laying ceramic tiles.
• Terraces & Balconies: As a primary waterproof membrane before tiling or finishing.
• Water Tanks & Sumps: Interior lining for concrete water retaining structures.
• Swimming Pools: Base waterproofing layer before final finishing coats.

How to Apply Dr. Fixit Pidifin 2K (Step-by-Step)

1. Surface Preparation: The surface must be structurally sound, clean, and free from loose material, dirt, or grease. Repair all existing cracks and structural defects.
2. Pre-Wetting: Dampen the substrate with water before applying the coating.
3. Mixing: Slowly add the powder component to the liquid component (A+B). Use a low-speed mechanical mixer to blend thoroughly until a smooth, lump-free slurry is achieved.
4. Application (1st Coat): Apply the first coat evenly with a stiff brush or roller. Work the material into the pores and texture of the substrate. Allow it to dry for 6-8 hours.
5. Application (2nd Coat): Apply the second coat perpendicular to the first (cross-direction). Allow to air cure fully for 7 days before filling water tanks or heavy traffic. Proper application is crucial for 2K systems.

Frequently Asked Questions (FAQ)

Q: Why is it called 2K (Two-Component)?
A: It consists of a polymer liquid (Component A) and a cement powder (Component B) that must be mixed on-site. This mixing creates the highly durable, flexible membrane.

Q: Can I tile directly over Dr. Fixit Pidifin 2K?
A: Yes, it provides an excellent waterproof base for applying tile adhesive and tiles. Ensure the 2K coating is fully cured first.

Q: Is it suitable for terraces exposed to the sun?
A: Yes, it is suitable. However, for terraces, it must be protected by a screed, mortar, or a final topcoat like Dr. Fixit Raincoat to prevent direct UV damage and traffic abrasion.
