FAQs

  • What is the difference between ready mixed filler and 2 part filler?

    Ready mixed fillers are pre-prepared and convenient for quick application, while 2 part fillers are more durable and ideal for deeper, stronger repairs, often used on wood and masonry.

  • How do I use quick drying filler?

    Quick drying filler is applied directly to the area needing repair and typically dries within 30 minutes, allowing you to sand and paint the surface on the same day.

  • Can expanding foam filler be used on large gaps?

    Yes, expanding foam filler is excellent for filling large gaps and cavities in walls, floors, and around pipes. It expands to fill the space and can be trimmed once dry.

  • What’s the best hole filler for wood?

    For wood surfaces, we recommend using a 2 part filler or quick drying wood filler. These options provide a strong bond and can be easily sanded and painted.
