Rubber Paint for Wooden Surfaces

Rubber Paint for Wooden Surfaces from SILK PLASTER is a flexible, waterproof and breathable coating that moves with the timber and protects fences, decking, cladding and other wooden surfaces. Below you will find surface preparation, application technique, coverage and long-term durability of Rubber Paint for Wooden Surfaces. Explore the full SILK PLASTER RUBBER PAINT range.

Wood is warm, attractive and environmentally friendly, but without protection it darkens, cracks and falls prey to fungus. SILK PLASTER RUBBER PAINT shields timber from moisture, ultraviolet light and biological attack while remaining elastic enough to move with the wood through seasonal humidity changes.

Where it works on wood

Wooden fences, gates and railings.
Decks, terraces and verandas.
Garden furniture and gazebos.
Soffits and roof eaves linings.
Wooden façades, tongue-and-groove cladding and timber imitation panels.
Outbuildings: sheds, wood stores, bath houses (external walls only).

Working with wood as a substrate

Wood breathes - it changes its linear dimensions as ambient humidity rises and falls. Rigid alkyd enamels split along the grain under such conditions. The elastic film of SILK PLASTER RUBBER PAINT absorbs that movement and stays intact.

The coating is vapour-permeable: moisture from the wood escapes freely instead of being trapped under the paint, which prevents blistering and rot.

Preparing the wood

Clean the surface of dust, dirt and flaking old paint. Sand off any grey, oxidised layer with medium-grit paper (P80-P120). Treat knots and resinous areas with an insulating primer to keep resin from bleeding through the new finish.

Fresh-sawn timber must dry to a moisture content of 12-15%. Always treat the wood with an antiseptic to protect it from mould, blue stain and insects. Once the antiseptic has dried, apply an acrylic primer formulated for wood.

Painting technique

Two coats are normally sufficient. The first may be thinned with 5-10% water - it sinks into the fibres and works as a binder. The second coat builds the colour and the decorative finish. Use a brush on profiled elements (balusters, mouldings) and a roller on flat boards.

Allow two hours between coats at +20 °C. Always work along the grain for a smoother appearance and to reduce the chance of patchy colour.

Conditions and limitations

Air and wood temperature should be between +5 °C and +30 °C, with relative humidity no higher than 80%. Do not paint wood that is still damp after rain, and avoid direct sunlight: a hot surface dries the paint too quickly and weakens adhesion.

Avoid use in areas where the wood is permanently submerged or in direct ground contact - those conditions call for dedicated oil-based impregnations.

Coverage and service life

Consumption is 200-400 g/m² in two coats; rough, unsanded wood takes more than planed timber. As a guide, 1 kg of paint covers about 5 m² in two coats.

Refreshing the finish does not require stripping the old paint: a light sanding and a fresh coat are enough. That makes wooden façades and decks much simpler to maintain.

Advantages for wood

Compared with translucent stains, rubber paint fully covers the grain and shields wood from UV, which helps protect the timber underneath. Compared with alkyd enamels, the coating does not split along the grain with seasonal movement and does not yellow in the sun.

The coating also forms a waterproof barrier, which matters most for garden furniture, fences and gazebos that stand permanently in the open.

Common mistakes on wood

Painting onto unseasoned timber (moisture above 15%) - leads to blistering and peeling.
Skipping the antiseptic - wood can still rot from within even under a paint film.
Ignoring knots and resin pockets - the resin bleeds through and leaves yellow stains. Use an insulating primer over these spots.
Painting across the grain - gives a less even texture and higher consumption. Always work along the grain.

Frequently asked questions

Can freshly sawn boards be painted? Only after they have dried to 12-15% moisture. Fresh-sawn timber takes three to six months to season depending on thickness.

Is the paint suitable for outdoor bath-house walls? Yes, for outer walls. Inside the steam room it is not used - the temperature and humidity are too high.

Can garden furniture be painted that people will sit on? Yes - once fully cured the coating is dry to the touch and does not transfer to clothing.

Do I need to strip a fence completely before repainting? Not if the old paint is firmly bonded. A light sanding and dusting are enough.
