EXTERIOR PROJECT GUIDE - Haymes Paint

SIMPLE STEPS TO A PERFECT EXTERIOR FINISH


1. WEATHERING
It is vital for optimum coating performance to ensure decking and exterior hardwood timbers are
weathered for a minimum of 4-6 weeks, while very dense timbers may require up to 6 months weathering.
The weathering time allows the grain of the timber to open, ensuring the coating can penetrate and
adhere. Regular watering during this period will assist the leaching of the tannins and extractives from
hardwood timbers. Check the timber is ready for coating by sprinkling with water. If the water beads,
allow further weathering time.


2. CLEAN THE TIMBER
Clean the timber with Simply Woodcare Wood Cleaner with a stiff scrubbing brush. Allow to stand for
10 minutes and then rinse off with water using a pressure cleaner as per directions. The cleaner will also
revive weathered/grey timber and will ensure all contaminants and extractives have been removed
from the surface of the timber so the coating can gain adequate penetration and adhesion.


3. PREPARE
Ensure all surfaces are clean, bare, dry and free of wax, grease and any contaminants prior to
application. The presence of contaminants will cause rejection and delamination. Fill nail holes if
necessary with Simply Woodcare Wood Putty, sand smooth and dust down. Preparation is paramount
to the performance and longevity of these products.


4. APPLY THE COATING
When the weather outlook is fine with no rain expected within 24 hours, you are then ready to apply
your coating. Ensure you have calculated your square metre area and have the correct amount of
product to coat at the correct film thickness, as this is vital to getting the optimum life, colour and
sheen from your timber coating. Apply generously along the length of the board, working 2-3 boards
at a time and ensuring that all exposed edges and end grain are coated.


5. MAINTENANCE
Periodically cleaning the surface with a mild detergent or Simply Woodcare Wood Cleaner will
rejuvenate the surface and extend the service life by removing contaminants, which can abrade
and damage the surface. It is important to reapply your coating when signs of sheen and colour
deterioration or general patchiness begin to show. Conducting regular inspections of your coating
will enable you to identify when re-application is necessary. To minimise the preparation required it is
recommended to recoat the surface before any bare timber is exposed.
Important: Always refer to the product data sheet or label for further information on preparation and
application specifications.
