Lesson Content/Board Summary

TECHNIQUES OF BUILDING PAINTING

Flat Painting

Flat painting is a basic technique where paint is applied evenly to a surface to create a uniform, smooth, and non-textured finish. It is often used as a base coat or for areas requiring a simple, clean look.

The following are common tools for flat painting:

Paint brushes
Paint rollers

Ragging

Ragging is a decorative painting technique that uses a crumpled rag to remove or apply paint, creating a soft, textured, and mottled effect on a surface. It gives an appearance of depth and movement.

The following are steps for ragging:

Apply a base coat of paint and allow it to dry.
Apply a contrasting glaze or thinned paint over the base coat.
While the glaze is still wet, gently dab and twist a crumpled rag over the surface to create the desired texture.

Sponging

Sponging is a decorative painting technique that uses a natural or synthetic sponge to dab paint onto a surface, creating a textured, dappled, or cloudy effect. It can add visual interest and depth.

The following are steps for sponging:

Apply a base coat of paint and allow it to dry.
Dip a damp sponge lightly into a contrasting colour of paint.
Dab the sponge gently onto the surface, overlapping the dabs to create a textured pattern.

Blow Lamp Method

The blow lamp method, often referred to as distressing or faux finishing with heat, is a technique used to create specific visual effects on wooden surfaces, such as accentuating wood grain or creating a burnt, aged look. It is typically used for decorative purposes on wood rather than general wall painting.

The following are safety precautions for the blow lamp method:

Work in a well-ventilated area.
Wear appropriate personal protective equipment (PPE) like safety goggles and heat-resistant gloves.
Keep a fire extinguisher or water source nearby.
Ensure the surface is free of highly flammable materials.

Spraying

Spraying is a method of applying paint by atomizing it into a fine mist and directing it onto a surface using a spray gun or machine. This technique provides a smooth, even, and professional finish with minimal brush marks.

The following are advantages of spraying:

Provides a uniform and smooth finish.
Faster application over large areas.
Can reach difficult-to-access areas.
Reduces brush marks and roller textures.

Instructional Procedures

Step 1: Introduction

Time: 5 minutes
Teaching Skill: Set Induction
Teacher’s Activity: The teacher greets the pupils and reviews the previous lesson on painting tools. The teacher then asks pupils to mention different ways they have seen paint applied to walls or furniture, leading them to the topic of painting techniques.
Pupils’ Activity: Pupils respond to questions and listen attentively.
Learning Point: Pupils recall prior knowledge and are introduced to the new topic.

Step 2: Flat Painting

Time: 8 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher defines flat painting and demonstrates how to apply paint evenly using a roller and a brush on a prepared surface. The teacher emphasizes achieving a smooth, uniform finish.
Pupils’ Activity: Pupils observe the demonstration and ask questions for clarification.
Learning Point: Pupils understand the concept and practical application of flat painting.

Step 3: Ragging

Time: 8 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher defines ragging and demonstrates the technique using a crumpled rag and two contrasting paint colours or a glaze. The teacher shows how to dab and twist the rag to create a textured effect.
Pupils’ Activity: Pupils pay attention to the steps and observe the resulting texture.
Learning Point: Pupils learn how to create a ragging effect.

Step 4: Sponging

Time: 8 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher defines sponging and demonstrates how to use a sponge to dab paint onto a surface, explaining how to achieve a dappled or mottled look. The teacher highlights the difference between ragging and sponging textures.
Pupils’ Activity: Pupils watch the demonstration and identify the unique characteristics of sponging.
Learning Point: Pupils learn how to create a sponging effect.

Step 5: Blow Lamp Method and Spraying

Time: 8 minutes
Teaching Skill: Explanation/Demonstration
Teacher’s Activity: The teacher explains the blow lamp method, emphasizing its use for distressing wood and the necessary safety precautions. The teacher then explains the spraying technique, showing a spray machine and discussing its advantages for achieving smooth finishes. (A brief, safe demonstration of the spray machine without paint may be done if feasible and safe).
Pupils’ Activity: Pupils listen to the explanations, note safety precautions, and observe the spray machine.
Learning Point: Pupils understand the blow lamp method and the principles of paint spraying.

Step 6: Practical Application/Pupil Activity

Time: 5 minutes
Teaching Skill: Practical Application/Supervision
Teacher’s Activity: The teacher provides small prepared boards, paint, rollers, brushes, rags, and sponges. The teacher supervises as pupils attempt to practice flat painting, ragging, and sponging techniques on their individual boards.
Pupils’ Activity: Pupils actively practice the demonstrated painting techniques.
Learning Point: Pupils develop practical skills in applying different painting techniques.

Step 7: Evaluation/Review

Time: 5 minutes

Teaching Skill: Questioning/Assessment

Teacher’s Activity: The teacher evaluates the learning by asking the following questions:

Define flat painting.
Mention two tools used for flat painting.
Explain the ragging technique.
Describe the sponging technique.
State two advantages of spraying paint.

Pupils’ Activity: Pupils answer orally and in writing.

Learning Point: Pupils demonstrate understanding of the lesson.

Step 8: Conclusion

Time: 3 minutes
Teaching Skill: Summarization
Teacher’s Activity: The teacher summarizes the key painting techniques discussed and demonstrated: flat painting, ragging, sponging, blow lamp method, and spraying. The teacher assigns homework, asking pupils to research other decorative painting techniques.
Pupils’ Activity: Pupils listen to the summary and copy the homework.
Learning Point: Pupils consolidate their learning and are encouraged to explore further.

Lesson Keywords

Flat Painting – Applying paint evenly for a smooth, uniform finish.
Ragging – A decorative technique using a crumpled rag to create a mottled texture.
Sponging – A decorative technique using a sponge to create a dappled or textured effect.
Blow Lamp Method – Using heat to distress wood or accentuate grain for decorative purposes.
Spraying – Applying paint as a fine mist using a spray machine for a smooth, even finish.

Differentiation

For pupils who grasp concepts quickly, the teacher can encourage them to experiment with combining different techniques or creating more complex patterns. For pupils needing more support, the teacher will provide closer supervision during practical sessions and offer simplified step-by-step guidance for each technique.

Note for teachers using this lesson plan

Ensure all materials are readily available before the lesson, especially for practical demonstrations. Prioritize safety during any demonstration involving a blow lamp or spray machine, ensuring proper ventilation and protective gear. Encourage active participation and hands-on practice to reinforce learning.
