Worked Solution & Example Answer:Wooden fencing and the entrance gate to the front garden of a house are shown in the accompanying sketch - Leaving Cert Construction Studies - Question 9 - 2009
Step 1
Outline two environmental reasons why wood is the preferred material for the fencing and gate.
Answer
-
Sustainability: Wood is a renewable resource that can be replenished quickly, reducing the ecological footprint compared to non-renewable materials.
-
Energy Efficient: The production of wood involves less energy and lower carbon emissions than materials such as steel or concrete. This contributes to a smaller overall environmental impact.
Step 2
Choose a suitable homegrown wood for the fencing and give two reasons for your choice.
Answer
- Larch: This type of wood is ideal for outdoor use due to its natural durability.
- It is preferred for posts as it is less likely to rot compared to other softwoods.
- Larch also has a long lifespan and a beautiful finish.
Step 3
Recommend a suitable applied finish to help preserve the wooden fencing from the weather. Using notes and neat freehand sketches, describe the steps involved in applying the finish to the fencing.
Answer
A suitable applied finish is Wood Preservative. The steps involved in applying the finish are as follows:
-
Preparation: Ensure the wood is clean and dry by removing any dirt or old finishes. Sand the surface lightly if necessary.
-
Apply the Preservative: Using a rolled brush or spray, apply the wood preservative evenly across all surfaces of the fencing. Avoid thick layers to prevent drips.
-
Drying Time: Allow the preservative to dry completely as per the manufacturer's instructions. This ensures effective penetration.
-
Coats: Apply two to three coats of preservative for optimal protection, ensuring to lightly sand in between coats for better adhesion.
-
Final Touches: Inspect the finish for any missed spots or uneven areas and touch up where necessary.
