To restore old garden furniture, deep-clean, repair, prime, and refinish with weather-ready products matched to the material.
Sun, rain, and grime wear down outdoor chairs and tables fast. The good news: most pieces bounce back with a clear plan and a weekend of steady work. This guide walks you through cleaning, repairs, primers, paints, oils, and topcoats for wood, metal, plastic, wicker, and fabric. You’ll also see tools, drying times, and simple tests that keep the finish looking sharp through the seasons.
Restoring Old Garden Furniture—Step-By-Step Plan
The workflow stays the same across materials: assess, wash, remove failed finish, fix, prime, coat, and cure. Follow the steps below, then jump to the material-specific sections for exact products and extra tips.
Quick Workflow
- Assess: Check for rot, loose joints, rust, cracks, UV chalking, or mildew. Photograph trouble spots.
- Wash: Use a bucket of warm water with mild detergent. Rinse and let parts dry fully.
- Remove Failures: Lift peeling paint, scrub rust, or sand weathered wood to a sound surface.
- Repair: Tighten fasteners, replace missing screws, plug holes, glue rungs, fill pits.
- Prime: Match primer to the substrate and chosen topcoat.
- Finish: Brush or spray coatings suited to outdoor use; follow recoat windows.
- Cure: Give full cure time before heavy use or stacking.

Safety Checks Before You Sand Or Strip
Old paint on benches or metal frames may contain lead. If the piece dates near the 1970s or earlier, use wet methods, capture dust, and follow lead-safe setup. The EPA’s lead-safe steps for DIYers outline testing, containment, PPE, and cleanup that keep dust out of living spaces.
For timber finishes, guidance from the Forest Products Laboratory shows how species, surface prep, and finish type change durability outdoors. Their wood finishing handbook explains film-forming vs. penetrating products, sanding ranges, and maintenance schedules.
Deep Clean: The Reset Every Piece Needs
Dirt and sunscreen form a sticky film that blocks primers and stains. Mix a few drops of dish soap in warm water and scrub every surface. Rinse well. Let parts dry to the touch; then wait longer. Moisture trapped under coatings blisters paint and clouds varnish.
Skip harsh bleach on bare wood unless you’re removing mildew stains; if you do use it, neutralize with plenty of water and allow extra dry time. Mildew loves shaded slats, fabrics, and end grain; target those zones first.
Wood: From Silver-Grey To Showpiece
Choose The Right Finish
Film finishes (exterior enamel, spar varnish) form a shell that sheds water and blocks UV. They look polished and clean easily. Penetrating finishes (deck oils, semi-transparent stains) soak into fibers, show grain, and are simple to refresh. The Forest Products Laboratory notes that species and surface texture change finish life; smoother planed boards hold film coats longer when prep is thorough.
Prep Steps
- Sand to remove grey fibers and loose finish. Stop at 120–150 grit for better mechanical key.
- Vacuum dust, then wipe with a barely damp cloth.
- Spot-fill checks or dings with exterior epoxy filler. Shape while green; sand flush after cure.
Finishing Options
- Exterior Enamel: Smoothest look and strong color. Use a bonding primer first. Two light coats beat one heavy flood.
- Spar Varnish (Marine Urethane): Tough film with UV absorbers. Multiple thin coats with light sanding between.
- Deck Oil / Penetrating Stain: Fast application and easy upkeep. Wipe off excess to avoid sticky spots.
Assembly And Hardware
Loose rungs and wobbly arms often need better joinery, not just screws. Reglue mortise-and-tenon joints with exterior-rated adhesive and clamp square. Swap rusted screws for stainless or coated deck screws. Add felt pads under feet to keep moisture off patio slabs.
Metal: Stop Rust, Lock Down Paint
Strip Back To Sound Material
On steel or iron, lift blisters with a scraper, then wire-brush to bright metal. Feather the edges of remaining paint with 120–180 grit. For pitted areas, a rust converter creates a stable base before primer. Follow label times before coating.
Prime For Grip And Corrosion Control
- Etch/Bonding Primer: Best for aluminum and powder-coated frames.
- Rust-Inhibiting Primer: Contains pigments that block moisture and oxygen.
Finish Coats
Use exterior metal enamel in satin or gloss. Spray gives an even skin on tubular frames; brush works well on flat strap seats. Multiple thin passes prevent sags and lap marks. Let the frame cure fully before bolting on slats or cushions.
Plastic And Resin: Renew Color And Sheen
Chalky plastic comes back with a scrub and a plastic-safe cleaner. Scuff glossy areas lightly with a grey pad. Use a primer labeled for plastic, then coat with an exterior paint approved for plastics. For white resin chairs, a careful clean and a color restorer or protectant spray often does the trick without paint.
Wicker And Rattan: Gentle Prep, Thin Coats
Vacuum dust from every weave. Tighten loose wraps with small dabs of exterior glue and clothespins as clamps. Spray paint is easier to snake into crevices than a brush. Keep passes light to avoid bridging that cracks later. For natural rattan under cover, a penetrating oil-varnish blend gives a warm glow with minimal buildup.
Fabrics: Fresh Sling Seats And Cushions
Wash removable covers as directed, then air-dry flat. For fixed sling fabric, scrub with a soft brush and a mix of water and gentle detergent. Rinse well. Sunbrella-type acrylics accept fabric-guard sprays once dry, which helps repel stains and dew.
Prime And Paint Like A Pro
Surface Temperatures And Weather Windows
Coatings need the right window to bond. Aim for a dry day with mild temps and low wind. Keep pieces in shade while you work; hot sun skins paint too fast and traps solvents.
Brush, Roll, Or Spray
- Brush: Best control on edges, carvings, and slats.
- Foam Roller: Fast coverage on flat arms and table tops; tip off with a brush.
- Rattle-Can / HVLP: Smooth finish on wire backs and tubes; more masking needed.
Test Pieces And Recoat Timing
Do a small test panel on the underside. If the film wrinkles, the old finish is solvent-sensitive—switch to a gentler primer. Obey the recoat window printed on the can; late recoats can cause poor adhesion.
Durability: Match Finish To Use And Care
Choose the finish based on how you use the set and how much upkeep you’re willing to do. The matrix below compares common paths across materials and maintenance habits.
| Material | Finish Choice | Typical Upkeep |
|---|---|---|
| Softwood | Exterior enamel over bonding primer | Wash each spring; touch up chips as they appear |
| Hardwood (Teak, Iroko) | Penetrating oil or clear sealer | Light clean mid-season; refresh oil once or twice a year |
| Steel/Iron | Rust-inhibiting primer + metal enamel | Inspect seams; spot-prime and spray small chips quickly |
| Aluminum | Etch primer + enamel, or clean and wax | Wash grime; wax mid-season to boost shine |
| Plastic/Resin | Plastic primer + exterior paint (if painting) | Clean quarterly; avoid strong solvents |
| Wicker/Rattan | Light spray coats; oil-varnish for natural | Vacuum dust often; small touch-ups each spring |
Common Problems And Fast Fixes
Peeling Paint On Arms And Seat Slats
That zone sees sun, skin oils, and sliding plates. Spot sand to a dull, even scratch, prime just the bare spots, then blend in topcoats. Feather edges so you can’t feel a ridge.
Rust At Welds And Under Feet
Moisture creeps into seams. Pop the plastic feet, dry the ends, treat rust, prime, and reinstall with new caps. Add small pads to keep legs off wet stone.
Sticky Varnish
Usually from heavy coats or cool temps. Scuff with a fine pad and give a thin coat. Let it cure in a dust-free corner with steady airflow.
Grey Wood That Turns Blotchy
Grey fibers must come off cleanly. Sand to fresh wood, wipe dust, and flood on the first oil coat evenly. Wipe all excess after 15–20 minutes.
Storage And Care So Work Lasts Longer
- Raise Off Ground: Pads or plastic glides keep water from wicking into feet.
- Cover Smart: Use breathable covers with tie-downs; avoid tarps pressed tight to wood.
- Mid-Season Wash: A bucket, mild soap, and a soft brush stop grime from chewing at the finish.
- Winter Plan: Store indoors or under a vented shelter. The RHS advises treating timber structures only in well-ventilated conditions and using legal, modern preservatives; older creosote types are not allowed in many regions. See their seasonal guidance on timber maintenance.
Material-Specific Mini Guides
Softwood Benches
Pine and similar species move with humidity and dent easily. A filled, primed, and painted system shields the fibers best. Keep edges thin with each coat so the film hugs the profile without drips.
Teak And Other Oily Hardwoods
These woods contain natural oils. Wipe with solvent just before coating to boost adhesion. If you like the honey tone, use a UV-blocking oil or clear sealer and refresh on a schedule. If you prefer silver, leave bare and clean once a year.
Cast Iron Details
Remove flaking paint, treat rust, and prime with a metal primer. For ornate scrolls, a small artist’s brush helps push primer into tight corners. Finish with two thin coats of enamel.
Powder-Coated Aluminum
Wash, scuff lightly, and spot-prime chips with an etch or bonding primer. Blend color with light spray passes. Wax can add gloss and make cleanup easy.
Resin Chairs
UV chalking wipes onto your hand as a white film. Clean, scuff, and restore with plastic-safe paint or a restorer spray if you’re keeping the original color.
Testing Your Finish Before You Sit
- Scratch Test: Press a fingernail in a hidden area. If it dents deeply, the film needs more cure time.
- Water Bead: Drip water on a flat. Tight beads mean good repellency; spread means the film needs refresh.
- Tape Pull: Stick painter’s tape on an edge and pull. If color lifts, the substrate needed better prep.
Project Planner: A Weekend Timeline

When To Call A Pro
If testing confirms lead in old coatings or if complex cast pieces need blasting, bring in certified help. The EPA RRP program lists rules and training for safe work on painted surfaces in older buildings and child-occupied spaces.
Final Checks Before You Move It Back Outside
- Wait for full cure, not just “dry to touch.”
- Pad contact points and tighten hardware.
- Log the product names and dates so touch-ups match later.
