Worked Solution & Example Answer:A terrace of traditional houses is shown in the accompanying sketch - Leaving Cert Construction Studies - Question 9 - 2010
Step 1
Discuss two reasons why it is advisable to repair the existing wooden windows in these houses rather than replace them with new windows.
Answer
-
Conservation of Existing Features: Repairing wooden windows helps to conserve the original features, style, and craftsmanship of traditional houses. This ensures that the architectural integrity and historical value of the buildings are maintained.
-
Environmental and Economic Benefits: Repairing windows is more environmentally friendly, reducing waste and the need for new materials. Additionally, it is often more economical as it avoids the costs associated with full window replacements, including materials and labor.
Step 2
Describe, using notes and neat freehand sketches, the steps to be followed when replacing a broken pane of glass in one of the windows.
Answer
-
Window Frame Preparation: Begin by removing the broken glass and any broken pins or fasteners from the rebate.
-
Cleaning and Sanding: Clean the area and sand the rebate to ensure good adhesion for the new glass.
-
Setting the Glass: Apply a layer of glazing compound to the rebate to act as a setting bed.
-
Installing New Glass: Carefully insert the new pane of glass, aligning it properly within the rebate.
-
Securing the Glass: Insert new glazing pins or fasteners to hold the glass securely in place.
-
Finishing Touches: Apply glazing compound around the perimeter to seal any gaps, ensuring to shape and trim any excess compound for a clean finish.
Step 3
Describe, using notes and neat freehand sketches, the steps to be followed when removing the existing paint, preparing the surface and repainting a window frame in one of the houses.
Answer
-
Protecting the Area: Place a cloth underneath the window to protect the floor from paint drips.
-
Removing Existing Paint: Use a heat gun, chemical stripper, or scraper to carefully remove the existing paint from the window frame.
-
Preparing the Surface: Ensure all surfaces are clean and dry before priming. Sand the frame to create a smooth surface.
-
Priming: Apply a coat of primer to the surface to protect the wood and ensure better adhesion for the paint.
-
Final Painting: Once the primer is dry, use a brush to apply the final coat of paint, ensuring even coverage.
-
Cleanup: Remove any painter’s tape used and clean the brushes and tools thoroughly.
