Best Caulk For Drywall Cracks

Persistent drywall cracks often result from expansion and contraction in wall surfaces, leading to repeated repairs if standard fillers are used. A flexible patching compound is essential for long-term results, especially in areas prone to movement.

DAP ElastoPatch stands out for its elastomeric formula that stays flexible over time, making it ideal for both interior and exterior use. It's a strong choice for homeowners seeking a solution that resists shrinking and cracking, especially in high-movement areas.

• Elastomeric flexibility: Remains flexible as surfaces expand and contract, preventing reoccurring cracks
• Tack-free in 30 minutes: Allows for quicker painting and finishing
• Superior paintability: Won't flash or gloss paint, ensuring seamless blending

Compared to standard spackles, ElastoPatch prioritizes flexibility and long-term durability. It is not sandable, so users needing a perfectly smooth finish may need to take extra care during application.
