Tetrion Smart Filler - 1L



Very tough

Fast setting

Doesn't shrink, crack or sag

Super smooth finish

As strong as wood!

Tetrion Smart Filler is a super lightweight filler which is ideal for filling large holes or hairline cracks in one easy application. It will not shrink, crack or slump and is super smooth with little or no sanding required. Microlite technology ensures Smart Filler sets 10x stronger than ordinary lightweight fillers, meaning you can nail or screw straight into the filler with no need for wall plugs or drilling. The fast-drying formula can be over-painted or wallpapered in 15 minutes and is suitable for use on a wide variety of substrates.

The Microlite glass bubbles present in Smart Filler help to keep the filler weight at an absolute minimum. The high strength nature of these glass bubbles means that Smart Filler can easily compete with traditional fillers when it comes to drilling, screwing and tapping.
