Indigo Crack Heal Paste (Protect Plus) – Waterproof Crack Filler

Indigo Crack Heal Paste (Protect Plus): Flexible, Ready-to-Use Crack Filler

Don’t let ugly cracks ruin your perfect paint job. Indigo Crack Heal Paste (Protect Plus) is a specialized, ready-to-use crack filler engineered to permanently repair hairline to medium-sized cracks (up to 5mm wide) in both interior and exterior plaster walls. This highly elastic paste moves with the wall, ensuring the crack doesn’t reappear through the paint layer.

Unlike regular wall putty that tends to crack or pop out when walls experience minor thermal movement, Indigo Crack Heal Paste features a polymer-rich, non-shrink formula. It cures into a tough yet flexible film that seals the crack completely, preparing the surface for a flawless coat of emulsion or exterior paint.

Why Choose Indigo Crack Heal Paste?

For long-term crack repair, professionals rely on flexibility and non-shrinkage:

• High Flexibility: The cured paste remains elastic, accommodating minor thermal expansion and contraction without cracking (a major advantage over rigid cement fillers).
• Ready-to-Use: No mixing is required. Open the container and start filling, saving time and ensuring a consistent material quality.
• Excellent Adhesion: Bonds strongly to masonry, concrete, plaster, and even old paint films.
• Water Resistance: Creates a waterproof barrier within the crack, preventing water ingress and subsequent dampness issues.

Key Features of Indigo Crack Heal Paste (Protect Plus)

• Type: Acrylic Polymer-Based Crack Filler (Paste Form).
• Crack Size: Ideal for cracks up to 5mm wide.
• Finish: Dries to a smooth, paintable surface.

How to Apply Indigo Crack Heal Paste

Follow these steps for a long-lasting, invisible repair:

1. Crack Preparation: Widen the crack into a ‘V’ shape using a putty knife or grinding tool. Remove all loose material, dust, and grease. The surface must be clean and dry.
2. Priming (Deep Cracks): For cracks deeper than 5mm, dampen the crack slightly to improve adhesion, but do not wet heavily.
3. Application: Apply Indigo Crack Heal Paste firmly into the crack using a putty knife. Press hard to ensure the paste fills the entire void from top to bottom. Overfill slightly.
4. Drying: Allow 6-8 hours for drying. Deep cracks may require longer curing time.
5. Finishing: Sand the excess paste flush with the wall using fine sandpaper (180-320 grit). Learn more about crack repair techniques.

Frequently Asked Questions (FAQ)

Q: Can I use this on moving expansion joints?
A: No, this is for non-structural cracks in plaster/masonry. For high-movement joints, you should use a dedicated silicone or polyurethane sealant.

Q: Does this need a topcoat?
A: Yes. The paste is porous and must be painted over with a primer and two coats of final paint (emulsion) to protect it from direct weather exposure and blend it visually with the wall.

Q: Can I fill large holes with this?
A: It is recommended for cracks up to 5mm. For larger holes or deep damage, use a combination of cement mortar and a repair polymer additive before using this paste for the final surface finish.
