Repairs - Exterior

Once the surface is clean, it is essential to check whether any repairs are required. Check the stability of the substrate itself to ensure the lasting good looks of your paint job.

Filling Cracks & Nail Holes
Any newly developed cracks, gaps or holes should be filled with a durable, paintable putty. Remember, silicone cannot be painted. A quality exterior grade or linseed oil putty should be used to fill exterior cracks and holes.

Secure any loose boards and replace loose or dry putty around windows. Once dry, sand the putty smooth. On timber surfaces, prime bare areas before filling cracks and holes.

Note: Nail Rust Problems
Always use galvanised nails on exterior surfaces to avoid problems with rusting and rust staining.
Otherwise, sand the heads of existing rusty nails to remove any rust and apply a rust inhibitor.
Punch the nails below the surface and fill the holes with exterior quality putty or linseed oil putty. Allow 48 hours drying time for linseed oil putties before painting.

Exterior Final Preparation
Once you've cleaned, repaired and sanded all surfaces, you should dust the area thoroughly.

Finally, you should carefully mask windows and other trims with masking tape or painters tape.

Tie plants back from the wall and protect all lawn and garden areas with drop cloths.
