What Customers Are Saying

Customers overwhelmingly praise this spackling compound for its innovative color-changing feature that transitions from blue to white when dry, eliminating guesswork about drying time. Reviewers consistently describe it as easy to apply with a smooth, toothpaste-like texture that spreads cleanly and dries quickly. Many highlight its superior durability compared to traditional spackling, delivering professional-looking, invisible repairs after sanding and painting. Users report successful results across diverse applications including wall holes, cracks, and mounting repairs on drywall and plaster. A small number mention texture inconsistencies or adhesion concerns, but the vast majority consider it a game-changing product worth keeping in their toolbox.

Would Recommend

Theres no color change its just white but it does the job and forms a good hard surface. Sands down nice so no real complaints on that front.

not blue

Would Not Recommend

I bought this about 6 weeks ago, finally got to use it yesterday. Open the product and started using it, finally realizing it not blue? It's already white! Had to patch holes. But today I return it and got the pink product from Dap, works as advertised. Lowes shouldn't even sell this product!
