Interior Wall Filler Powder

This multi-purpose natural filler powder can be used in a wide variety of circumstances, from filling small cracks in plasterboard to long ceiling cracks and even joints of wall ceramic tiles.

It comes in powder form which makes it ideal for mixing up just as much as you need at any one time. Handy to have about the home as it's an essential for interior decorating for preparing walls for paint or wallpaper.

Auro 329 can be used to fill cracks and small holes on interior plastered surfaces (lime plaster,  lime-cement plaster), calcareous sand, bricks, concrete or other absorbent mineral surfaces throughout your home.

Easy to use. Simply mix the powder with water (3:1 by volume, or 2:1 by weight) and work to a paste. Apply evenly. When a white film appears, wipe off excess with a damp cloth or sponge and polish with a cloth. On larger cracks or between tiles, moisten slightly after about 5 hours to ensure proper and even hardening.
