The best way to sand and repaint my eventing fences at home

Keeping a set of home eventing fences presentable is part of maintaining a useful training space, but the job is about more than making poles look fresh. Good preparation removes splinters, exposes weak timber, improves visibility and helps paint withstand rain, mud, horse traffic and the occasional enthusiastic brush against a rail. A neat fence can also make schooling feel more like a competition day for both horse and rider.

At home, I want Archie to read each obstacle clearly without creating a surface that is slippery, brittle or unnecessarily harsh. The best approach is a slow cycle of inspection, sanding, repairs, priming, painting and curing. Australian conditions make the timing important too: a hot, dry afternoon in inland New South Wales behaves very differently from a damp winter day in Melbourne or a humid summer morning in Queensland.

Start with a complete fence inspection

Before picking up a sander, I take every rail, filler and upright out of the training area and inspect it in good daylight. I look for rotten ends, deep cracks, raised fibres, loose fixings, bent brackets and sharp corners. Timber that feels soft when pressed with a screwdriver is not a painting problem; it needs replacing. The same applies to poles with structural splits or rails that have been weakened by repeated knocks.

I also check the way each obstacle is assembled. A painted plank may look sound while its support blocks are loose, and a decorative filler can become unstable if water has collected underneath it. Jumps should remain easy to move and should not have nails, screws or wire projecting into the horse’s path. Any breakaway components used for cross-country-style schooling should be checked separately and kept in working order.

This is a good time to separate equipment by material. Wooden rails, treated pine wings, plywood fillers and galvanised metal parts need different preparation. I avoid sanding anything that may contain old lead-based paint until I have identified the coating and chosen a safe removal method. Older properties and second-hand jumps can carry several layers of unknown paint, so a test kit or advice from a qualified professional is worthwhile.

Choose a dry Australian day

Paint manufacturers usually specify a suitable temperature and humidity range, and those instructions matter more than a convenient weekend. I aim for a dry, mild day with light wind, not the hottest part of summer. In western Sydney or Adelaide, a rail can become hot enough to affect paint flow surprisingly quickly. In Brisbane, humidity can leave timber damp overnight even when the afternoon feels warm.

The timber needs to be properly dry before sanding and coating. If the fences have been rained on, I give them several days under cover with plenty of airflow, checking shaded ends and the underside of rails. A moisture meter is useful, although a simple delay after wet weather is better than sealing dampness beneath fresh paint. Painting over moisture often leads to blistering, peeling and mould stains.

Shade is preferable while the coating dries, but the area should not be enclosed without ventilation. I place rails on trestles or clean supports so air can reach all sides, leaving enough room to turn them safely. A calm autumn day around Canberra can be ideal, while a windy rural property may need the work postponed because dust, leaves and insects quickly become part of the finish.

Remove loose paint before sanding

I begin with a stiff brush or scraper to remove flaking paint, mud, cobwebs and loose fibres. The aim is not always to strip every old layer back to bare timber. Sound, well-adhered paint can usually remain, provided its edges are feathered smoothly and the surface is clean. Complete removal takes much longer and can damage soft timber if done aggressively.

For ordinary timber poles, a random-orbit sander makes the work faster, but I use it carefully around edges and avoid creating flat spots on round rails. Coarse paper is useful for lifting damaged paint, followed by a medium grit to smooth the transition and a finer grit for the final surface. Hand sanding is safer around corners, joints and narrow decorative pieces. I keep the sander moving because holding it in one place can gouge pine.

Dust control is important around horses and people. I work outdoors, wear safety glasses, hearing protection and a properly fitted respirator suitable for the dust and coating involved. Dry sweeping spreads fine particles across the yard, so I collect sanding dust with a suitable vacuum or use damp cleaning methods after the dust has settled. Horses stay well away until the sanding, cleaning and painting have finished.

Repair and prime the timber

Once the old coating has been removed, I inspect the bare areas again. Small non-structural holes can be filled with an exterior timber filler, then sanded flush after curing. I do not use filler to disguise a split rail or repair a rotten wing. Those pieces are replaced, because a cosmetic patch cannot restore the strength needed when a horse hits or leans on a fence.

For outdoor eventing jumps, I choose a coating system made for exterior timber rather than an indoor enamel. An exterior acrylic can be practical because it dries relatively quickly and is available in strong colours, while a suitable water-based decking or outdoor trim product may work for particular components. I check the label for compatibility with the primer and for use on previously painted timber. Paint from Bunnings, Mitre 10 or a rural supplies shop is only useful when it matches the preparation and weather exposure.

Primer is particularly valuable on fresh timber, exposed end grain and areas where the old finish has been sanded away. I seal cut ends carefully, since they absorb water readily. Two thin primer coats are generally easier to control than one heavy coat. I allow the stated drying time rather than relying on touch-dryness; cool evenings and high humidity can leave the lower layers soft.

Use colour for visibility and discipline

Bright, contrasting colours help a horse distinguish the rails, especially when schooling in changing light. White, black, green, blue and red are common choices, but I prefer combinations that stand out against the background of my arena. A white rail in front of pale sand can disappear at a distance, while dark green may blend into trees. Testing a small painted section from the normal approach can reveal this before the whole set is coated.

I use masking tape for clean stripes and mark measurements before opening the tin. Consistent widths make a home course look orderly and help me set a repeatable exercise. On Archie’s rails, I favour several light coats rather than loading the brush until paint runs down the sides. A mini roller can give a smooth finish on broad plywood fillers, while a good exterior brush reaches end grain, corners and textured areas.

The visible finish should never be allowed to create a slippery contact surface. I avoid painting the top of a rail immediately before use and never add glossy products that could make a wet pole difficult to grip or read. If a manufacturer recommends a particular recoat interval, I follow it closely. Paint that feels dry on the surface may still be soft underneath, especially in a closed shed.

Allow enough time for curing

Freshly painted fences need more time than the label’s minimum handling period when they will return to an active arena. I leave rails supported off the ground and turn them so every side can breathe. The obstacle is not ready simply because it can be lifted without leaving a thumbprint. Heavy poles, stacked fillers and damp timber can retain moisture for days.

I keep horses away from the work zone while the coating cures and remove all tape, rags, abrasive paper and empty containers before reopening the area. Paint flakes and solvents are obvious hazards, but small screws, staples and broken brush handles are just as easy to miss around a jump storage area. Used rags and leftover products are stored or disposed of according to the label and local council requirements.

Before the first schooling session, I run a gloved hand over each rail and inspect every edge. I look for rough patches, lifted fibres, runs that have hardened into sharp ridges and fittings that have loosened during handling. I then move the fences back into position without jumping them, checking that the wings sit firmly and that the rails remain easy to remove.

Maintain the finish between competitions

A repaint should form part of a regular maintenance routine rather than a once-a-year rescue job. After wet weather, I clear mud from the lower sections and let the equipment dry before stacking it. Rails last longer when they are stored off the ground with space between them. Leaving timber in long grass or against a damp fence line encourages rot at the ends.

I inspect the obstacles before each busy training period and touch up small chips before water reaches the timber. Touch-up paint should be feathered into the surrounding surface, not brushed over dirt or loose flakes. If a rail starts splitting, I take it out of use immediately. Keeping a few spare poles is often less expensive and safer than trying to extend the life of damaged wood.

Competition standards still apply when a home fence is used for serious training. A painted obstacle that looks like a cross-country fence may not have the correct construction, dimensions or frangible safety features for an official event. I use home jumps to practise lines, rhythm and confidence, then check the relevant Equestrian Australia or event organiser requirements before assuming a design is competition-compliant. With that distinction clear, a clean, well-maintained set of fences gives Archie a consistent schooling environment and makes every repainting session worthwhile.
