Heavy-Duty Concrete Crack Repair Adhesive 100 gm Pack of 1

Seal hairline to small cracks fast—clean finish, strong bond, and paint-ready after cure.

Fix visible cracks in concrete floors, walls and pathways with this heavy-duty crack repair adhesive. Formulated for masonry and cement-based surfaces, it flows into gaps, bonds firmly and helps restore a smooth, paint-ready finish. Ideal for home repairs on balconies, driveways, garages, kitchens and bathrooms. Supplied as a single 100 g pack; outer package size is approximately 30 × 25 × 10 cm.

This crack repair adhesive is designed to penetrate fine gaps and small non-structural cracks so your surfaces look neat and stay protected from dust and moisture ingress. On cleaned, dry concrete, it fills, levels and cures to a hard finish that can be sanded lightly and over-painted once fully set. Use it on interior and exterior cement plaster, concrete floors, skirting edges and steps where hairline cracks or small chips spoil the look. For best results, widen very fine cracks into a shallow “V”, remove all loose dust, make sure the area is dry, then apply in thin layers, smoothing each pass. Allow adequate curing time based on temperature and humidity. This 100 g pack is meant for targeted repairs, touch-ups and small areas.

Specifications

This listing includes one 100 g pack of Heavy-Duty Concrete Crack Repair Adhesive. It is intended for hairline to small cracks in concrete and cementitious substrates and is suitable for both indoor and outdoor applications on stable, non-moving areas. Colour and final shade may vary slightly after curing and painting. Package dimensions are approximately 30 × 25 × 10 cm for shipping protection.

Directions for Use

Ensure the surface is sound, clean and completely dry. Brush out dust and debris; degrease if needed. For best adhesion on hairline cracks, open them slightly into a shallow V-groove with a scraper. Apply the adhesive into the crack with a nozzle or spatula, working from one end to the other to push material deep inside. Level the surface with a putty knife; for wider gaps, build in thin layers, allowing a skin to form before the next pass. Avoid water contact during cure. After full cure, sand lightly if required and paint with compatible coatings.

Safety & Compatibility

Use gloves and work in a well-ventilated area. Avoid skin and eye contact; keep away from children and pets. Do not use on constantly wet, oily or dusty surfaces, active leak points, expansion joints, or structural cracks where movement is present—consult a professional for those. Always test on a small inconspicuous patch for paint compatibility and finish. Curing time varies with temperature and humidity; allow adequate time before sanding or painting.

FAQs (Q&A format)

Q1. What types of cracks can this fix?
It is intended for hairline to small non-structural cracks in concrete and cement plaster—floors, walls, skirting and steps. It is not meant for structural repairs or moving joints.

Q2. Can I use it outdoors?
Yes, on clean, dry, stable concrete surfaces. Avoid application during rain or on damp substrates; allow full cure before exposing to water.

Q3. How long does it take to cure?
Cure time depends on temperature, humidity and crack depth. Thin applications can become touch-dry within hours; allow sufficient time—typically from several hours to a day—before sanding or painting.

Q4. Is it paintable?
Yes, once fully cured and lightly sanded for a smooth profile. Use compatible masonry/concrete paints or primers as recommended by the paint manufacturer.

Q5. Will one 100 g pack be enough?
One pack is suitable for small areas and touch-ups. For multiple cracks or wider gaps, consider more than one pack to ensure proper filling in thin, controlled layers.

Q6. Can I apply it on damp or dusty surfaces?
No. Surfaces must be clean, dry and free from dust, oil and loose particles for proper bonding and long-term performance.

Q7. Is it suitable for potholes or large cavities?
No. Large voids, potholes and structural damages require bulk repair mortars or professional repair systems.
