DIY Cosmetic Renovation: A Step-by-Step Guide for Beginners

A cosmetic renovation is the most affordable way to change how your apartment looks without big expenses or months of chaos. Painting walls, new wallpaper, fresh skirting boards and new flooring are within reach even of people who have never held a roller. The key is proper preparation and sequence. This guide covers everything you need for a professional-looking result.

What a Cosmetic Renovation Includes

A cosmetic renovation doesn't touch utilities or structures. It usually means:

• painting or wallpapering walls;
• refreshing the ceiling;
• replacing flooring;
• replacing skirting boards, architraves and door handles;
• renewing sealant in the bathroom and kitchen;
• replacing light fittings, sockets and switches (electrical work — following safety rules or by an electrician).

If you need new wiring or pipes, wall leveling with plaster or moving partitions, that's a major renovation. For that, see our apartment renovation guide.

Step 1. Plan and Budget

1. Walk through the apartment with a notebook and write down what you want to change in each room.
2. Measure areas of walls (minus windows and doors), ceilings and floors.
3. Choose materials and calculate quantities with a 10–15% margin.
4. Set the order — from dirty to clean work, top to bottom: ceiling → walls → floor → skirting and hardware.
5. Keep a reserve of 10–15% for unexpected costs.

Renovate room by room — that way the apartment stays livable.

Step 2. Tools

A basic kit:

• rollers (medium nap for walls, with an extension pole for ceilings) and a tray;
• brushes of various widths for corners and edges;
• spatulas (wide and narrow), sandpaper and a sanding block;
• masking tape and protective film;
• a level and tape measure;
• a utility knife with spare blades, scissors;
• a stepladder;
• for flooring — a saw or jigsaw, a square, spacers;
• protective gear: goggles, a respirator, gloves.

Step 3. Preparation Is 70% of Success

Clear and Protect the Space

Move furniture out or into the middle and cover it with film. Cover the floor. Remove socket and switch covers (with the circuit switched off) and tape skirting boards, window frames and door frames.

Prepare the Walls

• strip old wallpaper — soak it with warm water and a little detergent or a special solution;
• remove flaking paint and plaster;
• fill cracks and holes with filler and sand once dry;
• remove grease and soot stains;
• if there's mold, treat it with an antiseptic and find the cause of the damp (see mold and damp prevention);
• apply primer — it evens out absorption and improves paint or adhesive bonding.

Watch out for old paints. Buildings constructed decades ago may contain lead-based paint. The US Environmental Protection Agency (EPA) recommends not dry-sanding such surfaces and protecting your lungs, especially if children or pregnant women live in the apartment.

Step 4. The Ceiling

Paint the ceiling first, since drips inevitably land on the walls.

1. Clean it and fill cracks if needed.
2. Prime.
3. Cut in corners and edges with a brush.
4. Apply the first coat with a roller in strips parallel to the window, the second perpendicular.

Choose matte paint for ceilings — it hides imperfections.

Step 5. Walls: Paint or Wallpaper

How to Choose Paint

• Living rooms — matte or eggshell acrylic or latex paint.
• Kitchen, hallway, children's room — washable paint with a high scrub resistance class.
• Bathroom — paint for humid rooms with antifungal additives.

Pay attention to the content of volatile organic compounds (VOCs). The EPA notes that paints and solvents are a source of indoor air pollution (EPA: indoor air quality). Choose low-VOC paints and ventilate well.

How to Paint

1. Stir the paint and thin if needed according to the instructions.
2. Cut in corners and edges along the ceiling and skirting with a brush.
3. Apply paint with a roller in W-shaped strokes, spreading it evenly.
4. Paint a wall in one go without stopping midway — otherwise you'll see lap marks.
5. Apply the second coat after the first has fully dried.

How to Hang Wallpaper

• Non-woven — easiest for beginners: paste goes on the wall and the sheets don't stretch.
• Vinyl on non-woven backing — durable and washable, suits hallways and kitchens.
• Paper — cheap but needs experience.

Process: mark a vertical line for the first strip with a level, cut sheets with 5–10 cm extra, butt the joints, smooth out air from the center to the edges, and wipe off excess paste immediately with a damp sponge. Avoid drafts while hanging and drying.

Step 6. Flooring

The easiest DIY floors are click-lock types:

• laminate — affordable and hard-wearing;
• vinyl flooring (SPC, LVT) — water-resistant, suits kitchens too;
• engineered wood — a natural look, but more expensive.

The subfloor must be level and dry. Laminate goes on an underlay. Leave an 8–10 mm expansion gap at the walls and stagger end joints in adjacent rows. How to choose flooring for each room is in our flooring guide.

Step 7. Finishing Touches

• Skirting boards — fit after the floor, covering the expansion gap.
• Sockets and switches — replacing cover plates is easy, but only work with the circuit switched off. If wiring is old or sparks, call an electrician — see apartment electrical wiring.
• Sealant in the bathroom and kitchen — remove the old bead, degrease the joint and apply sanitary silicone.
• Lighting — new warm-light fittings change how a space feels. LED bulbs use much less energy.
• Textiles and decor — curtains, cushions, plants.

How to Choose Colors

Wall color affects how a space feels more than any furniture. A few proven rules:

• Light warm shades — milky white, beige, light gray with a warm undertone — make a room look bigger and suit most furniture.
• Cool shades — light blue, gray-green — suit sunny south-facing rooms and feel calming.
• Dark colors — graphite, deep blue, olive — feel cozy but "eat" space; use them on a single accent wall.
• The 60–30–10 rule: 60% main wall color, 30% secondary (furniture, textiles), 10% accents.
• Test the color on the wall. Paint a 50×50 cm patch and look at it morning, afternoon and evening — color changes with the light.

Small rooms benefit especially from the ideas in small apartment design.

How to Refresh a Kitchen Without Replacing It

Replacing a kitchen is expensive, but cosmetic changes make a noticeable difference:

• paint the fronts with special furniture paint after degreasing and priming, or cover them with quality film;
• replace the handles with modern ones — the cheapest way to update the look;
• update the splashback — washable paint, a glass panel or tiles over the old ones with suitable adhesive;
• replace the faucet and the lights over the worktop;
• renew the sealant around the sink and worktop.

If the kitchen needs full replacement, plan it with the tips in kitchen renovation.

Safety First

DIY work is satisfying, but a few rules prevent injuries and expensive damage:

• always switch off the circuit at the panel before touching sockets, switches or light fittings, and check with a tester;
• use a stable stepladder and don't overreach — move the ladder instead;
• wear goggles and a respirator when sanding, stripping or working overhead;
• keep solvents and paints away from heat sources and children;
• ventilate during and after painting until the smell is gone;
• don't drill blindly near sockets and switches — cables usually run vertically and horizontally from them.

How Long It Takes

Roughly, for one 15–18 m² room:

• preparation — 1–2 days;
• ceiling — 1 day plus drying;
• walls — 2–3 days;
• floor — 1 day;
• finishing — 1 day.

That's about a week per room if you work on weekends and evenings.

How to Save

• Buy materials from one batch to avoid shade differences.
• Compare prices in DIY stores and online.
• Reuse existing furniture by updating fronts or hardware.
• Paint walls instead of buying expensive wallpaper.
• Don't skimp on primer and tools — they affect the result.

Common Mistakes

• Skipping primer — paint goes on patchy and wallpaper peels.
• Painting over dust or greasy stains.
• One thick coat instead of two thin ones.
• Laying laminate without an expansion gap — in summer it buckles.
• Working at low temperatures or high humidity — drying is disrupted.
• Buying materials "by eye" without a margin.

Renovating for Sale or Rent

A cosmetic renovation is the most effective way to prepare an apartment for sale or rent. Neutral colors, washable paints and hard-wearing floors increase appeal and speed up the deal. More ideas in renovation for rental and how to sell an apartment fast.

Frequently Asked Questions

Can I paint over old wallpaper? Not recommended: the wallpaper can soak and come away, and its texture will show through the paint.

How many coats of paint do I need? Usually two. For a dramatic color change — three, or a tinted primer first.

Do I need to notify the condominium association? No, but warn neighbors about noisy work and respect quiet hours.

When should I call a professional? If walls are very uneven and need plastering, if there are electrical or plumbing problems, or if you don't have time. How to choose one is in how to choose a renovation contractor.

Can I renovate in winter? Yes, if the apartment is warm (at least +10…+15 °C depending on manufacturers' requirements) and humidity is moderate. Ventilate in short bursts so walls don't cool down.

What do I do with construction waste? Don't leave it next to household waste bins. Agree removal with the condominium association or manager, or order a skip from a specialist service.

Conclusion

A DIY cosmetic renovation means real savings and the satisfaction of the result. Prepare surfaces carefully, follow the "ceiling — walls — floor" order, choose quality low-emission materials and don't rush the drying. Your refreshed apartment will please you for years.
