Finishing

Chestnut Finishing Oil is Chestnuts' version of Danish Oil* and uses Tung Oil as its base but with the addition of solvents and driers. This aids the drying of the product and speeds it up dramatically, so that it’s dry within eight hours. It has a pale amber colour and dries to a hard yet flexible film which is very hardwearing and water resistant. For a high gloss finish apply several coats with a light rub down between coats; after 5 or 6 coats a good sheen should be visible. Finishing Oil is normally applied by cloth but on larger areas a brush can be used very successfully.

Tung Oil, or Chinese Wood Oil as it’s sometimes called, is a natural oil derived from the seed of the nut of the tung tree. The jury is out as to whether it can spark a nut allergy. Tung Oil air dries to form a tough, hard film that has a fairly strong amber tint. Because it doesn’t have any solvent or driers in it it can take a while to dry, and dependant on conditions this can be up to a week although 48 hours is more common. As with most finishes a thinner coat will dry quicker. Normally applied with a brush or cloth.

If you’re looking for a finish that won’t change the colour of your timber, won’t overpower the natural beauty of the wood with a high gloss but will still protect the timber and smell nice, well, you’re in the right place! Lemon Oil is a clear, low build finish. By that we mean that it’s a very thin liquid with a very low solids content, so no matter how much you apply it’s not going to build up to a discernible visible film on the surface. Instead it soaks in and seals the surface, offering a level of water resistance and protection against handling. Normally applied with a brush or a cloth it’s very  easy to use and covers well and doesn’t usually show overlaps, so it’s ideal for large areas which often look better without a high gloss. And as you might expect, it has a pleasant lemon aroma too, although this does fade after a while.

If you need to get away from the smell and flammability of our cellulose based lacquers this is an ideal option. This water based lacquer has virtually no smell and is totally non-flammable. Don’t be fooled though, this product is extremely hard wearing and gives a full gloss finish. Being water based it is slightly slower drying, taking about twenty minutes to be touch dry. If you want to apply a second coat it should be left two hours before doing so, although a wax can be applied if required after about thirty minutes. This product can be sprayed if suitable equipment is available, or can be applied by cloth or brush. We recommend foam brushes for application as this keeps the foaming action of acrylics to a minimum.  

Confusingly, French Polish refers to a range of polishes (which would include Button Polish, White Polish, Garnet Polish etc) and also to a specific polish, French Polish. Chestnuts' French Polish is a traditional blend of solvent (methylated spirit) and a top quality unbleached shellac which is very similar to a Button Polish in colour. Applied either to bare timber or over a Shellac Sanding Sealer it is built up in many layers which have been described as being the thickness of a cigarette paper! French Polish gives the rich amber glow found on fine antique furniture and requires a very specific technique for application that is time consuming and laborious, but the final effect has to be seen to be believed and the satisfaction of achieving it is its own reward. A French Polish finish is not very hard wearing and is recommended for items that are going to be cared for.

This creamy liquid has a very mild abrasive within it which acts like ‘liquid sandpaper’ on finished surfaces, cutting back and cleaning the finish and elevating it to a glossier, brighter finish. It can be used to smooth Cellulose Sanding Sealer prior to applying wax or Friction Polish, or, after allowing a suitable time to dry, on any of the lacquers, Friction Polish, Finishing Oil or Hard Wax Oil. A deep finish can be achieved using Burnishing Cream on a coat of Melamine Lacquer, then a coat of Friction Polish and finally the Burnishing Cream again. Use it sparingly so as not to over lubricate the surface and be sure to shake the bottle before use. It is not advisable to use a lacquer on top of a surface that has had Burnishing Cream used on it.

Cut’n’Polish is a blend of two waxes with a fine abrasive held in suspension within them. This is a soft wax designed to stay ‘wet’ slightly longer during application, allowing it to lubricate the abrasive to give a very fine cut to the timber and also to collect any dust generated during use and some subsequent sanding, preventing it from entering the workshop atmosphere. On bare wood; sand to 240 grit as normal, apply a coat of Cut’n’Polish with the lathe stopped, then switch on the lathe and buff to a soft sheen whilst smoothing the timber at the same time. On sealed wood apply after the sealer in the same way, polishing to a slightly higher shine. Cut’n’Polish dries almost immediately and can be overcoated with Friction Polish or any Chestnut waxes for a higher shine.

Chestnut Products’ Microcrystalline Wax is a blend of high quality waxes rich in microcrystalline wax – a wax derived from the petroleum refining process and known for the fineness of its crystals. This is mixed with a special solvent to create a firm wax which, when dry, knits down to form a very dense coating making it very water resistant, meaning that it is ideal for any items that are likely to come into contact with water for short periods of time. Microcrystalline waxes also have a higher melting point than other waxes traditionally used to make polishing waxes, the benefit of which is that repeated handling of items finished in Microcrystalline Wax won’t finger mark in the same way, as the melting point is higher than normal body temperature. Microcrystalline Wax should be used over one of the Chestnut Products’ sanding sealers and allowed to dry (about 20 minutes) before buffing to a shine. For best results apply a very thin coat, spreading the wax evenly over the entire surface. Microcrystalline Wax can also be used on the buffing wheel system. In this situation use the A and B Wheel as normal, then apply the Microcrystalline Wax to the item you are polishing. Allow 20 minutes for the wax to dry then buff and normal using the C Wheel. You can use the same C Wheel for both Microcrystalline Wax  and the Carnuaba Wax Stick.  Microcrystalline Wax has been tested to the EN71 Part 3 regulations regarding coatings used on toys.

If you don’t have access to spraying equipment, this aerosol lacquer will give you a great finish quickly and easily. A spray application is particularly relevant when trying to achieve the best gloss finish possible. Acrylic Gloss Lacquer is a high build water based lacquer specially adapted to give the best delivery through the nozzle (chosen to give excellent results without spitting, spotting or clogging in normal use) without, of course, the use of CFCs. The lacquer itself dries quickly to give a high gloss finish straight from the can which has the benefit of being extremely hard wearing and durable – so much so that it can be used on items that will be kept outdoors or used in areas where moisture could damage other finishes. Acrylic Gloss Lacquer is touch dry and tack free in around five minutes and hard dry in twenty minutes, ready for a second coat if needed after a light rubdown with a fine abrasive. The sheen level can be increased if required by using Burnishing Cream (which will not affect the durability) or, after allowing 24 hours to ensure it is completely hard dry, by using it in conjunction with the Buffing Wheel Kit.

When you need to protect your work but don’t want an overpowering shine on it, Acrylic Satin Lacquer is an ideal choice. With the benefit of an easy aerosol application, especially useful on awkward shapes, this is a hard wearing water based lacquer that will protect whatever it’s put onto, leaving an attractive satin sheen. Acrylic Satin Lacquer is touch dry and dust free in about five minutes and hard dry about 20 minutes, ready for a second coat if needed after a light cut back with a fine abrasive. For best results it should be used over either Cellulose Sanding Sealer or the Acrylic Sanding Sealer aerosol. If you have a change of heart on the finish the lacquer can be brought to a gloss by using either Burnishing Cream or the Buffing Wheel Kit. Or you can simply apply a coat of Acrylic Gloss Lacquer!

Woodturners stick wax is a mixture of beeswax and carnauba wax it is slightly softer than the Carnauba Wax Stick and therefore slightly easier to apply and there are no concerns about it marking softer woods. Applied over a sanding sealer, simply hold the stick against the revolving work and allow the heat generated to melt the wax onto the wood. Buff up straight away using Safety Cloth, using the cloth to ensure an even coating.

This is a solid block of carnauba wax, popular with woodturners. It gives a bright gloss finish and is also very hard wearing, able to withstand a medium amount of handling without showing finger marks. Apply over a sanding sealer by holding it against your work at it revolves on the lathe. Do not press too much – the wax is very hard and can scratch softer woods – the idea is to generate enough heat for the wax to melt slightly and transfer onto the wood. (This is easier than it sounds!). Use sparingly, and use the polishing process (using safety cloth) to ensure the wax is spread evenly. Buffing will produce a high gloss finish.

End Seal is an emulsified paraffin wax used the seal the ends of freshly cut timber to slow down the drying process and reduce the risk of the timber splitting. It can also be used on work-in-progress that is being left unfinished where there is a risk of the timber splitting. Apply it liberally, normally by brush but it can be sprayed if needed, usually to the smallest surface of the timber which will normally be the end grain where moisture is most likely to escape from. Sealing the surface will encourage the moisture to escape via the larger areas which will result in a slower exit.

Safety Cloth is a thick, non-woven paper cloth. Designed to stay wet longer to assist the transfer of finishes to your chosen surface, it also tears very easily if it gets caught in revolving parts thus avoiding the danger of fingers being dragged into machinery. The texture of Safety Cloth ensures that a thin, even coat is applied and the thickness means that it retains it’s strength and the same piece can be used several times with the same finish. Safety Cloth is not a replacement for common sense and good safety practise.

The finest of Steel Wool, very low crumble and virtually oil free to ensure there is no contamination of your work. Use it after sanding with abrasive sheets to give an ultra smooth surface, or to apply waxes to smooth the timber whilst applying a thin coat. Steel Wool burns very quickly and easily; keep it away from sources of combustion (i.e. sparks etc). Always use a knife or scissors to cut Steel Wool
