Two or three coats

3

What main characteristic of vinyl and aluminum siding must you be aware of during installation?

Vinyl siding is very sensitive to temperature changes and must be allowed to expand and contract.

4

Where is flashing used?

Flashing is used at all horizontal joints of exterior components, except where the upper surface overlaps the lower.

5

When is flashing installed?

Flashing is installed first so the building paper or house wrap that is installed over it will carry water onto the flashing.

6

Why is soffit vented?

Must be vented to allow air flow into the roof space.

7

Exterior finishes that are adversely affected by moisture must be kept how high above finished grade?

200 mm above finished grade.

8

List 4 steps in the preparation for siding installation.

1. Install flashing
2. Install sheathing membrane
3. Install trims, dividers and corners.
4. Calculate exposures (e.g., a storey pole)

9

Define exposure as it relates to siding.

The exposure is the amount of siding visible after the overlapping of courses.

10

When installing vinyl corner posts, where does nailing start?

Nailing starts at the top of the top nailing slot so the posts are hung from there.

11

Where is J-channel used?

J-channel is used as trim around windows and doors, around any items that project through the wall and where the siding meets another exterior finish.

12

What allowances should be made when cutting vinyl or aluminum siding panels that will meet windows, doors, and corner posts?

Allowances should be made to keep the siding panels 6 mm (1/4") from corner posts and channels to allow for expansion and contraction.

13

Of what are siding nails made?

Aluminum, galvanized or stainless steel. Large head, 3 mm shank, and are 38 mm long for standard applications.

14

How long should the nails be that are used for fastening vinyl siding to sheathing?

Nails must be long enough to penetrate the sheathing and must not be nailed tight.

15

Describe the depth and placement of nails for vinyl and aluminum siding.

Nails should be placed in the centre of slots. They must not be nailed tight, but must be kept 1 mm from the siding to allow movement due to expansion and contraction.

16

How should the butt joints between siding panels be placed as siding progresses up the wall?

Joints should be vertically staggered.

17

When is undersill trim used?

Undersill trim is used any time the top or bottom locking strip has been removed.

18

Where is the most common place to start installation of vertical siding?

Vertical siding is installed from the centre of the wall.

Name 3 methods of finishing the outside corners of wood siding?

1. Mitred corners
2. Metal caps
3. Constructing a corner post

20

Describe what must be done to prepare for the first course of bevel or clapboard wood siding.

Siding styles such as bevel or clapboard need to have furring installed in order for the first course to have a similar slope to the remaining courses.

21

Where should joints in wood siding occur?

Joints in siding courses should occur over framing, using a scarf joint.

22

What must be done to the wall to prepare for vertical wood siding that is not required for a horizontal application?

Support must be added for the fastening of vertical siding in the form of blocking between studs or strapping.

23

When is it most efficient to install soffit and fascia?

Before the wall finish, but it is common to delay it until the wall finding progresses to the final courses so that scaffold can be set up once for both operations.

24

What finishing is required for an open cornice?

Installation of blocking and a notched frieze board to close in the space between rafters.

25

What is the cornice return?

Junction between the rake and horizontal soffit.

26

What must be done at joints between aluminum siding and brick?

Aluminum will react with the lime in concrete products, so these must always be separated by a dividing material or by a space and caulking.

27

What makes wire stucco lath self-furring?

Mesh has bumps on it to make it self-furring (keeps it 6 mm (1/4") away from the wall surface).

28

What must be done to building corners prior to stucco application?

Corners must be reinforced by installing a strip of expanded metal mesh to extend 6" (150mm) on both sides of the corner.

29

Name and briefly describe the 3 coats necessary for stucco application.

1) first coat is called the scratch coat because the surface is scored or scratched to provide better bonding for the next coat.

2) the second coat is the brown coat, which is lightly roughened and dampened to accept the final coat.

3) the third coat is the finish coat

30

Coats of stucco must be kept at what temperature and for how long?

Stucco must be maintained at a temperature of 10 C for 48 hours after application.

32

List 3 methods of support for masonry veneer?

33

In brick veneers, how much air space must be left behind the brick to allow for drainage and ventilation?

25 mm (1")

34

How is brick veneer attached to the framed wall?

The brick veneer must be tied to the framed wall with corrosion-resistant ties nailed to the framing and embedded in the mortar joint.

How will the junction between veneer and soffit be finished?

A frieze board must be installed at the top of the wall. This board is fastened
