How to look after DPR products that
are to be used in an exposed application |
Step1
If the timber is going to be used at a later date then it is important to
minimise surface checking * by applying a base coat of an oil based primer
and then storing the timber in a flat, elevated position protected from
the sun and rain.
Step 2
Before and during construction ensure that all timbers are primed,
including joints.
Step 3
Apply Two (2) top coats with either an acrylic or oil based enamel.
Please note: For advice relating to different paint systems
available it is recommended that you consult with your local paint
supplier.
* Surface checking is a natural process whereby unseasoned timber dries
out. As a consequence fine cracks (checking) appear. These checks will
close again with time once the centre of the piece dries out. Coating the
timber helps to minimise checking by slowing down the moisture loss. |

DPR is supplied in three grades |
| F14 |
Graded for strength, not
good looks |
| F17 |
Graded for strength, not
good looks** |
| Appearance Grade |
Graded for its lack of
natural characteristics *** |
| **F17 is
stronger than F14, however 98% of the F17 spans can be substituted with
F14, which means substantial savings. Ask your Architect or designer to
apply the DPR span tables to your
project for maximum value. |
***Appearance
grade excludes natural characteristics such as gum vein, loose knots, grub
and insect holes. A rule of thumb is "if you can't see any defect
after you paint it then it's appearance grade"
NB...DPR
is not supplied to furniture grade specifications. |
