I am currently painting my weatherboard house, I found this fascia board had some wood rot, instead of replacing the whole board, I replaced a section of the the rotted timber using Cyprus pine pickets cut and glue to shape, I used Sikaflex polyurethane glue to fit it in place
Materials
Materials used

Sikaflex polyurethane glue
Tools

Router, to cut slot for water run off.
Steps
Step 1

Rotted fascia

Cut out damaged area

Fabricate and glue up new replacement cypress pine timber

Router a slot for water run off to match existing fascia board

When glue has dried, sand and shape new piece of timber to fit in place, then glue and clamp in place

Now it’s ready to undercoat and finish paint

Now for the rest of the house.
Has any got any suggested to prevent future timber rot/decay ?
