Why Shrink & Crack Resistant Matters

Many cheaper fillers shrink as they dry, leaving a slight depression in the repair that becomes visible once painted — requiring a second application. 151 Instant Filler’s shrink and crack resistant formula is designed to maintain its volume as it dries, reducing the need for multiple coats and giving you a flush, paint-ready surface first time. The crack resistant formula also means the repair is less likely to crack over time as the wall naturally expands and contracts with temperature changes.

How to Use

• Ensure the surface is clean, dry, and free from loose material, dust, and grease
• Cut the nozzle to the desired bead size and load the cartridge into a sealant gun
• Apply the filler to the crack or hole, slightly overfilling to allow for any minor shrinkage
• Smooth with a filling knife or damp finger for a neat finish
• Allow to dry fully – the filler will turn from off-white to bright white when dry
• Sand smooth with fine-grade sandpaper once fully dry
• Apply a second coat if required for deeper holes or cracks
• Paint over once fully dry and sanded smooth
