Dr. Fixit Crack-X Paste – Flexible Acrylic Crack Filler

Dr. Fixit Crack-X Paste: The Ready-to-Use Solution for Wall Crack Repair

Hairline cracks are common on plaster walls, but if left untreated, they can allow water seepage and ruin your expensive paint finish. Dr. Fixit Crack-X Paste is a polymer-based, ready-to-use crack filler designed for static cracks up to 5mm wide in vertical walls and ceilings. This unique paste offers high elasticity and excellent adhesion, ensuring that once the crack is sealed, it stays sealed.

Unlike cement-based fillers which are rigid and tend to shrink or crack again with minor structural movement, Dr. Fixit Crack-X Paste is flexible. It moves with the wall, bridging the crack effectively and providing a smooth, paintable surface that blends seamlessly with the surrounding plaster.

Why Choose Dr. Fixit Crack-X Paste?

This ready-mixed paste simplifies crack repair, offering professional-grade results without complex mixing:

• Ready-to-Use: No mixing with cement or water required. Open the container and start application, ensuring consistent quality every time.
• High Elasticity: The polymer base provides flexibility, preventing reappearance of the crack due to minor thermal expansion and contraction.
• Excellent Adhesion: Bonds strongly to common building materials like plaster, cement, and masonry.
• Paintable Finish: Dries to a smooth, non-shrink surface that accepts all types of interior and exterior emulsion paints.

How to Apply Dr. Fixit Crack-X Paste (Step-by-Step)

1. Surface Preparation: Ensure the crack is clean, dry, and free from dust, oil, or loose plaster. Widen the crack slightly (V-grooving) for better adhesion.
2. Application: Apply the Dr. Fixit Crack-X Paste directly into the crack using a narrow putty knife or spatula. Press firmly to ensure deep penetration.
3. Finishing: Smooth the paste flush with the wall surface immediately after application. For deep cracks, apply the paste in thin layers, allowing 7-8 hours between coats.
4. Curing: Allow the filled area to dry completely (24 hours is recommended, depending on depth and climate).
5. Painting: Lightly sand the cured paste with fine-grit sandpaper if needed, and then apply a primer before the final paint coat. Proper crack preparation is key for invisible repairs.
