Question 1

1. Decorators caulk vs filler – what’s the difference?

Accepted Answer

Decorators caulk is flexible and used to seal gaps that may shift slightly over time, like those between walls and trim. Filler is rigid and used to patch static holes or cracks in walls or ceilings before painting.

Question 2

2. What’s the difference between putty and filler?

Accepted Answer

Putty is oil-based and mainly used in glazing to secure glass panes. Filler is water-based or ready-mixed and used to repair surfaces like plaster or wood.

Question 3

3. Can I use filler instead of caulking?

Accepted Answer

Not usually, since these products are designed for different situations. Filler lacks the flexibility of caulk and can crack if used in joints subject to movement.
