Technical Article – Filler and how they behave

As a flooring contractor with many years of experience sanding and coating floors, I have seen a lot of different putties and fillers – each one promising that they are the best and will solve all my problems. I used to apply filler such as oil putty using a putty knife and a ball of filler, pressing and slicing in one action, to fill nail holes. Cracks were a time- consuming task... These types used to fade quickly in sunlight, so I shifted to a powder type that mixed with water. Add in a paint tinter concentrate – then voila! Just don’t mix too much, or it will set rock hard while you wait.
