How Do I Apply Filler?

To ﬁ ll nail holes, repair scratches, dents, and gouges,

simply sand the affected area lightly with a ﬁ ne or extra

ﬁ ne sandpaper using a sanding block (see Sanding).

Always use a non-shrinking ﬁ ller. A light weight Spackle or

Shur-Patch is best. Follow the manufacturer’s directions

to achieve best results. For stainable mouldings use a

ﬁ ller that closely matches the wood colour. Once holes

have been ﬁ lled and allowed to dry, lightly sand these

areas to remove any rough spots.

How Do I Sand Mouldings?

Use a ﬁ ne grit sanding sponge or

at least a 220-grit sandpaper on a

sanding block. Always sand with

the grain of the wood (Fig.12).

Coarser grits of sandpaper, or

going across or against the grain

will tend to leave ﬁ ne gouges that

may be visible through subsequent

coats of paint. A very light pass over the nail area will

sufﬁ ce. If you have purchased natural ﬁ nish mouldings,

such as unﬁ n ished Finger-Joint Pine, they will require

priming before installation. A high quality primer is

recommended. Touch sanding with a ﬁ ne grit (220 or

higher) sandpaper between each coat is strongly recom-

mended. This light sanding will ensure better bond between

the coats, and also give a smoother ﬁ nal ﬁ nish.

When to apply Paint or Stain.

Staining or painting the moulding before it is installed is

recommended. Ensure all areas that have ﬁ ller are dry

and sanded before applying any paint. If you install the

moulding and then ﬁ nish it, protect the area around the

moulding by masking it off with tape. Carefully remove

the tape immediately after ﬁ nishing to prevent its drying to

the ﬁ nish. Painting is recommended for moulding surfaces

already coated with a primer. In most applications a

semigloss coat for durability, washability, and appearance

is recommended. Please ensure that only higher quality

paints with high solids content are used. We recommend

two ﬁ nish coats for top quality durability and appearance.

Mouldings with a pronounced wood grain are better suited

to stain or varnish to enhance the naturally occurring grain.

Other mouldings such as hemlock can be stained to

virtually any tint, but also provide a high quality surface

for paint as well when primed. The Following list shows

the recommended ﬁ nishing.

What Tools Do I Need?

HANDY TIP

Using a compound mitre saw and a compressed air

brad nailer will not only make all stages of installing

decorative mouldings easier but it will also speed up

the process considerably.

NOTE: Always wear eye, ear and respiratory protection

when doing any home improvement project.

How Much Do I Need?

Take careful measurements of walls, windows etc. and

round up to the nearest foot. Add 10% extra for cutting

and waste.

Which Proﬁ les Do I Need?

For windows and doors use casings, for ceilings use

crowns, for ﬂ oors use baseboards, and for walls use chair

rails, panel moulds etc. Use the Moulding & Millwork

Catalogues or Charts to choose the right proﬁ le numbers

to suit your needs and decor.

How Do I Mitre a Moulding?

Most moulding mitre joints are at a 90° angle (Fig.1)

and consist of 2 pieces of moulding cut at opposing

45° angles. When ﬁ tted together they should form

a tight right angle. For tight mitre joints, nail and glue

at joint as shown. (Fig.2)

How do I do a return?

A return is where the proﬁ le of a moulding is carried

from the front of the proﬁ le around to the wall to give the

ends an appealing and ﬁ nished look. This is commonly

done on door and window headers, chair rails, mantels,

and handrails. To do a return, measure the overall width

of the header etc, then cut both outside edges at 45°

angles back toward the header. Then cut your return

pieces at opposite 45° and then trim them to the correct

thickness to return to the wall.

To fill nail holes, repair scratches, dents, and gouges, simply sand the affected area lightly with a fine or extra fine sandpaper using a sanding block (see Sanding). Always use a non-shrinking filler. A light weight Spackle or Shur-Patch is best. Follow the manufacturer’s directions to achieve best results.
