Dr. Fixit Crack-X Paste
Ready-to-Use Acrylic Crack Filler Paste for Concrete, Plaster, and Masonry Surface Cracks
Authorized Project Distributor — Dr. Fixit by Pidilite | Space Arc Engineering, Ghaziabad
Product Overview
Dr. Fixit Crack-X Paste is a ready-to-use, water-based acrylic crack sealing compound from Pidilite Industries designed for the simple and effective repair of hairline cracks, fine surface cracks, and minor surface defects in interior and exterior concrete, cement plaster, brick masonry, and gypsum board surfaces. It is supplied in a tube or tub as a smooth, white paste that can be applied directly from the container using a finger, putty knife, or small spatula without any mixing, thinning, or site preparation of the product itself. After application into and over the crack, Crack-X Paste dries and cures to a hard, sandable, paintable surface that can be finished flush with the surrounding wall or ceiling surface and painted over with any standard interior or exterior paint, eliminating the crack from the painted surface appearance. Crack-X Paste is particularly formulated for the very fine, random shrinkage cracks that develop in cement plaster and concrete surfaces across the surface of Indian buildings over time — the result of cement carbonation shrinkage, thermal cycling, and minor drying movement. These hairline cracks (typically 0.1 to 0.3 mm wide) are too fine for conventional cementitious or epoxy fillers to penetrate and fill effectively, but the Crack-X Paste acrylic formulation has the right consistency and adhesion to be worked into the finest hairline crack with a flexible blade and to adhere firmly to the crack walls after drying. The dried Crack-X Paste film is slightly flexible, reducing the risk of the repair cracking again under minor subsequent thermal movement. It is available in standard white and can be painted over with any colour paint after drying. Space Arc Engineering supplies Dr. Fixit Crack-X Paste for building maintenance, renovation, and pre-paint surface preparation across Delhi NCR, Ghaziabad, and Uttar Pradesh.
Applications
- Hairline and fine crack repair in interior cement plaster walls and ceilings before painting
- Surface crack sealing in exterior plaster before application of exterior paint or waterproofing coating
- Crack repair in concrete columns, beams, and slabs for cosmetic surface finish restoration
- Sealing fine cracks in gypsum board (drywall) partitions and ceilings
- Pre-paint surface defect repair — blowholes, pinholes, and minor plaster imperfections
- Filling nail holes and screw holes in interior walls before repainting
Key Advantages
- Ready-to-use paste — apply directly with finger or spatula, no mixing required
- Penetrates fine hairline cracks — acrylic paste works into cracks below 0.3 mm width
- Sandable and paintable after drying — seamless finish for interior and exterior surfaces
- Slightly flexible when cured — accommodates minor thermal movement without re-cracking
- Economical and available widely — small tubes for repair jobs, large tubs for contractors
- Adheres to concrete, plaster, brick, and gypsum board without primer

Frequently Asked Questions
What is the difference between Dr. Fixit Crack-X Paste and Dr. Fixit Crack-X for structural crack repair and which should be used on an exterior wall?
Dr. Fixit Crack-X Paste and the broader Dr. Fixit Crack-X range serve different crack types and require different approaches. Crack-X Paste is a cosmetic surface crack filler suitable for: hairline and fine non-structural surface cracks (typically less than 1 to 2 mm wide) in cement plaster and concrete that do not involve structural movement; interior and exterior plaster surface repairs where the final surface will be painted; and situations where a simple, quick repair is needed without specialist equipment. It is not suitable for: structural cracks in reinforced concrete beams, columns, or slabs where load transfer through the crack section is a design consideration; active cracks that continue to open and widen (Crack-X Paste will re-crack if the substrate movement continues); water-bearing cracks where hydrostatic pressure pushes water through the crack (Crack-X Paste is not a hydraulic sealant); or cracks wider than approximately 3 mm where a mortar or epoxy filler provides better mechanical fill. For exterior walls with existing hairline cracks before application of Dr. Fixit Raincoat or another exterior waterproofing: Crack-X Paste is suitable for spot-filling individual visible surface cracks before priming and coating. However, if the exterior wall has extensive fine cracking (map cracking or crazing over large areas), it is more efficient to apply a full coat of Dr. Fixit Raincoat (which has its own crack-bridging capability) over the primed surface rather than attempting to fill every individual hairline crack with Crack-X Paste. For cracks wider than 2 to 3 mm in exterior walls, use a polyurethane sealant (such as Dr. Fixit PU sealant) or cement-sand mortar filler before coating, as these provide better depth fill and movement accommodation than Crack-X Paste.
