Surface Preparation Techniques
Knowledge check
Q1. What is the main purpose of sanding a surface before painting?
- A. To add color to the surface
- B. To smooth rough areas and help the paint adhere better ✓
- C. To make the surface waterproof
- D. To remove the need for primer
Why: Sanding removes roughness, bumps, and loose material, creating a smooth, even surface that allows paint to bond properly and produce a consistent finish.
Q2. Which tool is most suitable for removing old, flaking paint from a wooden window frame?
- A. A paint roller
- B. A paint scraper ✓
- C. A paint brush
- D. A spray gun
Why: A paint scraper is designed to lift and remove loose or flaking paint layers from surfaces such as wood, making it the right tool for this task.
Q3. Why should you clean a surface with a degreaser before painting a kitchen wall?
- A. Grease can prevent paint from adhering and cause it to peel ✓
- B. Degreasers make paint dry faster
- C. Grease makes paint more glossy
- D. Degreasers are needed to thin the paint
Why: Grease and cooking residue create a barrier that stops paint from bonding to the wall, so removing it with a degreaser helps prevent peeling and poor adhesion.
Q4. What should you do with small holes and cracks in a wall before painting?
- A. Ignore them, as paint will hide them
- B. Fill them with filler, let it dry, then sand smooth ✓
- C. Cover them with tape
- D. Paint over them with extra coats
Why: Filling holes and cracks with a suitable filler, allowing it to dry fully, and sanding it flush creates an even surface so defects do not show through the finished paint.
Q5. Why is it important to allow a freshly prepared surface to dry completely before applying primer or paint?
- A. Wet surfaces make paint more expensive
- B. Moisture can cause paint to blister, peel, or fail to adhere ✓
- C. Drying makes the surface harder to sand
- D. Paint only works on dry wood by law
Why: Trapped moisture can push paint off the surface or cause blistering and peeling, so the surface must be fully dry for the coating to bond and last.

- A. To mix paint colours together
- B. To protect floors and furniture from paint splashes and debris ✓
- C. To help paint dry faster
- D. To thin the paint before application
Why: Dust sheets protect floors, furniture and fittings from drips, splashes and dust created during preparation and painting.
Q4. Which material is most appropriate for priming bare plasterboard before applying emulsion paint?
- A. Gloss paint
- B. Varnish
- C. A plasterboard primer or sealer ✓
- D. Wallpaper paste
Why: A dedicated plasterboard primer or sealer is designed to seal the porous surface and ensure even paint absorption and adhesion.
Q5. Why should you use masking tape with clean, sharp edges when painting window frames?
- A. It makes the paint thicker
- B. It keeps paint off the glass and adjacent surfaces, giving crisp lines ✓
- C. It speeds up drying time
- D. It removes old paint automatically
Why: Good quality masking tape creates a neat barrier, protecting glass and surrounding surfaces and producing clean, sharp paint lines.

Q1. Which type of paint is most commonly used for interior walls because it is easy to clean and resists moisture?
- A. Distemper
- B. Emulsion (latex) ✓
- C. Gloss oil-based paint
- D. Limewash
Why: Emulsion, also called latex paint, is water-based, dries quickly, has low odour, and can be wiped clean, making it the standard choice for most interior walls and ceilings.
Q2. What is the main difference between water-based and oil-based paints?
- A. Water-based paints are always more expensive
- B. Oil-based paints use water as a solvent and clean up with soap
- C. Water-based paints use water as a solvent and clean up with water, while oil-based paints use mineral spirits or white spirit ✓
- D. Oil-based paints cannot be applied to wood
Why: Water-based paints use water as the thinning and cleaning agent, whereas oil-based paints require solvents such as white spirit or mineral turpentine for thinning and cleaning brushes and tools.
Q3. What does the term 'gloss level' describe in paint?
- A. The colour intensity of the paint
- B. How much light the dried paint film reflects ✓
- C. How thick the paint is when applied
- D. How long the paint takes to dry
Why: Gloss level describes the amount of light a dried paint surface reflects. Flat or matt finishes reflect very little light, while gloss finishes reflect a lot, which affects both appearance and durability.
Q4. Which paint finish is generally best for kitchens and bathrooms because it is the most washable?
- A. Flat matt
- B. Eggshell
- C. Satin or semi-gloss ✓
- D. Chalk paint
Why: Satin and semi-gloss finishes have a smooth, slightly reflective surface that is more durable and easier to scrub than flat or matt finishes, so they suit high-moisture, high-wear areas like kitchens and bathrooms.
Q5. What is the purpose of a primer before applying topcoat paint?
- A. To change the colour of the topcoat
- B. To make the paint dry faster
- C. To seal the surface, improve adhesion, and provide a uniform base for the topcoat ✓
- D. To remove old paint from the surface
Why: Primer seals porous or bare surfaces, promotes adhesion of the topcoat, and creates an even base, which helps the finish look consistent and last longer.

Colour Theory and Planning
Knowledge check
Q1. Which three colours are considered primary colours in traditional paint mixing?
- A. Red, green, and blue
- B. Red, yellow, and blue ✓
- C. Orange, green, and purple
- D. Yellow, green, and black
Why: Red, yellow, and blue are the primary pigment colours because they cannot be made by mixing other colours together, and they can be combined to create all other colours. Red, green, and blue are primary colours for light (RGB), not for paint.
Q2. What colour do you get when you mix blue and yellow paint?
- A. Purple
- B. Orange
- C. Green ✓
- D. Brown
Why: Blue and yellow are primary colours, and mixing them together produces green, a secondary colour. Purple comes from red and blue, and orange from red and yellow.
Q3. Which term describes a colour's lightness or darkness?
- A. Hue
- B. Saturation
- C. Value ✓
- D. Temperature
Why: Value refers to how light or dark a colour is. Hue is the colour name itself, saturation is its intensity or purity, and temperature describes whether it feels warm or cool.
Q4. Which colours are considered warm colours on the colour wheel?
- A. Blue, green, and purple
- B. Red, orange, and yellow ✓
- C. Black, grey, and white
- D. Brown, cream, and beige
Why: Warm colours include red, orange, and yellow, which are associated with sunlight, fire, and energy. Cool colours such as blue, green, and purple tend to make a room feel calmer and more spacious.
Q5. What is the purpose of a colour wheel when planning a decorating scheme?
- A. To calculate the cost of paint needed
- B. To show how colours relate to each other and help choose harmonious combinations ✓
- C. To measure the moisture level of a wall
- D. To determine how many coats of paint are required
Why: A colour wheel shows how colours relate to one another, such as complementary colours opposite each other, and helps decorators choose schemes that work well together before any paint is bought or applied.

Application Methods and Finishing
Knowledge check
Q1. Which tool is best suited for applying paint smoothly to the edges and corners of a room before using a roller on large areas?
- A. A paint roller with a long nap
- B. A paintbrush (cutting in) ✓
- C. A spray gun
- D. A paint pad
Why: Cutting in with a paintbrush allows precise paint application along edges, corners, and where walls meet ceilings or trim, before the roller fills in the large open areas.
Q2. What is the main purpose of applying a primer before a topcoat of paint?
- A. To make the paint dry more slowly
- B. To seal the surface, improve adhesion, and provide an even base for the topcoat ✓
- C. To change the final colour of the paint
- D. To remove old paint layers completely
Why: Primer seals porous surfaces, improves paint adhesion, helps block stains, and creates a uniform base so the topcoat looks even and lasts longer.
Q3. When using a roller, in which pattern should you apply paint to help avoid visible lap marks?
- A. Random zigzags across the wall
- B. Small circles in one spot
- C. A W or M shape, then filling in while the paint is still wet ✓
- D. Straight vertical lines only, from top to bottom in one pass
Why: Rolling in a W or M pattern spreads paint evenly, and filling in while the edge is still wet (keeping a wet edge) prevents visible overlap or lap marks as the paint dries.
Q4. Why should you stir paint thoroughly before use, even if it was recently mixed in the shop?
- A. To add air bubbles for a smoother finish
- B. To make the paint thicker
- C. To ensure pigments and binders are evenly distributed, giving a consistent colour and finish ✓
- D. To speed up the drying time
Why: Pigments and solids settle during storage. Stirring thoroughly redistributes them so the colour, sheen, and consistency are uniform across the whole batch.
Q5. Which finish is generally most suitable for a bathroom or kitchen wall because it is easy to wipe clean and resists moisture?
- A. Flat (matt) emulsion
- B. Limewash
- C. Eggshell or satin ✓
- D. Distemper
Why: Eggshell and satin finishes have a slight sheen that makes surfaces more durable and easier to wipe clean, which is ideal for areas exposed to moisture, grease, and steam.

Module 7: Clean-Up and Final Inspection
Clean-Up and Final Inspection
Knowledge check
Q1. After completing a painting job, what should be done first with leftover paint that is still usable?
- A. Pour it down the drain to dispose of it
- B. Seal the lid tightly, label the can, and store it in a cool, dry place ✓
- C. Leave the can open so it dries out completely
- D. Mix it with water and store it in a plastic bottle
Why: Leftover paint should be sealed, clearly labeled with the colour and location used, and stored cool and dry so it can be used for touch-ups later. Pouring paint down the drain is harmful to the environment and often prohibited.
Q2. Which tool is most suitable for removing dried paint splatter from a window pane during final clean-up?
- A. A wire brush
- B. A razor blade scraper held at a shallow angle ✓
- C. A steel wool pad
- D. A coarse sandpaper block
Why: A razor blade scraper held at a shallow angle removes dried paint from glass without scratching it. Wire brushes and steel wool would scratch the glass, and coarse sandpaper would leave permanent marks.
Q3. During the final inspection of a painted room, what is the best lighting condition for spotting missed areas, drips, or uneven coverage?
- A. Direct overhead light only
- B. Bright sunlight from directly in front of the wall
- C. Raking light, where light strikes the wall at a low angle ✓
- D. Complete darkness with a torch
Why: Raking light, which strikes the surface at a low angle, casts shadows that reveal roller marks, missed patches, drips, and uneven sheen that are hard to see under direct, flat lighting.
Q4. Why should masking tape be removed soon after the final coat of paint is applied, while the paint is still slightly tacky?
- A. Tape removal is easier when paint is wet and it prevents the paint from pulling away ✓
- B. Paint dries faster when tape is left on
- C. Tape adhesive hardens the paint permanently
- D. The tape must be removed before the primer is applied
Why: Removing tape while the paint is still slightly tacky, typically within an hour or so depending on conditions, gives a clean edge and prevents the paint film from peeling or tearing when the tape is lifted after it has fully cured.
Q5. Which method is the correct way to clean brushes at the end of a job when using water-based (latex) paint?
- A. Soak them in paint thinner overnight
- B. Rinse thoroughly in warm soapy water until the water runs clear, then reshape the bristles and dry them flat or hanging ✓
- C. Leave them in the paint tin to keep them soft
- D. Wash them in boiling water to dissolve the paint
Why: Water-based paints clean up with warm soapy water. Rinsing until the water runs clear removes residue, and reshaping the bristles before drying keeps the brush in good condition. Paint thinner is for solvent-based paints, and boiling water can damage bristles and handles.
