Why strip wooden furniture?

Give your furniture a makeover


alt

Stripping a piece of wooden furniture is great for giving your pieces a fresh lease of life or a new look to chime in with the rest of your interior.

Apply a fungicidal or insecticidal treatment

Furniture can fall victim to wood-eating insects. It's not uncommon to find a cupboardinfested byfurniture beetles or a shelf filled with wood worms or mites. Stripping your furniture will help to offer greater protection. This will allow products to penetrate the material more effectively as varnishing or painting furniture creates an airtight seal. If you want to treat the wood properly, you must start by preparing your surface.

Different methods of stripping wood

There are three main ways to strip a piece of wooden furniture. We'll cover these techniques below as well as a fourth method which often proves effective and offers an excellent finish.

With more than one way to strip wooden furniture, your decision will come down to a few criteria.

  • The type of furniture: is your furniture partially upholstered? Does it have any glazed surfaces? Any moulding? Is it made up of large, flat surfaces? Is it curved? Are you dealing with a chair? Or a wardrobe? A table?
  • The size of the surface you want to strip: you may need to invest in specialist tools, depending on how large your surface is.
  • Your choice of stripping products : for example, there's no point in applying strong chemicals if you're only looking to strip wax.
  • The number of layers you want to strip: some furniture items have been painted and repainted so much that you'll find yourseld stripping away three layers rather than one.
  • The type of finish you want: your choice of tools and products will depend on your standards and the amount of time you're willing to spend.
  • The types of tools you have at your disposal: for example, do you have a compressor? Or just some nylon paint brushes? What about a heat gun? Are you planning to use this project as an excuse to invest in some new tools?

You'll soon realise that some stripping jobs should only be started if you have the right tools at hand; otherwise, you run the risk of ending up with a less than satisfactory result. There are several different stripping techniques.

  • Sandblasting: this will require the use of an air compressor, a sandblaster gun and some sand.
  • Thermal blasting: requires the use of a heat gun and the right nozzles for your surface.
  • Chemical stripping: involves applying a chemical stripper or some caustic soda with a nylon paint brush (while wearing personal protective equipment).
  • Sanding: using the right type of sander for your surface. While you can strip a surface by sanding alone, this is also an essential part of the three techniques described above (preferably using a fine grit sandpaper).

Removing wax from a piece of furniture is considered a separate process to stripping.

3 essential steps to stripping furniture

1. Examine the material you want to remove


alt

Before you start stripping, you will have to determine whether you are working with wax or varnish. To do so, wet a cloth with some rubbing alcohol and wipe it against part of the furniture. If the cloth takes on the colour of the furniture, the piece is coated in wax; if the cloth doesn't change colour, it has been varnished. You can also carry out a similar test using fine grit sandpaper: if the paper gets clogged up, it's wax; if you get dust, it's varnish.

2. Stripping your furniture


alt

Your choice of stripping technique depends on your tools, the type of furniture you're working with, the surface you aim to strip and the type of finish you want. You can keep your job environmentally friendly by choosing eco-friendly products. Safety goggles, gloves and a protective mask will be required.

3. Sanding



alt

Whether you've decided to sandblast, heat blast or chemically strip, you simply have to rid your surfaces of all wood paint, lacquer, wax, gilding, varnish, walnut stain or bleaching agents such as oxalic acid (also known as wood bleach).

Stripping with a sandblaster

Sandblasting is a very effective stripping technique and provides impeccable results. It is best done outdoors or in a well-ventilated space indoors. Under no circumstances should you attempt to sandblast your dresser while it's still in the living room next to the TV! Sandblasting allows you to strip every last corner with ease; you can tackle corners, moulding, cornices and sculpted wood with no trouble at all. Finish by giving your furniture a once over with a fine grit sandpaper and your work is done!

  • Tools required : compressorsandblastersandblasting kit or handheld sandblasting gun, sand.
  • PPE: safety goggles, noise-cancelling headphones and mask with respiratory protection.

Applying a chemical stripper

Stripping wooden furniture using a chemical stripper is effective but does require more time and isn't usually the most environmentally friendly option. Chemical strippers should be applied using a nylon paint brush in a well-ventilated area. The ground should be protected with a tarp, old cardboard boxes or newspaper. You must apply your stripper according to the manufacturer's instructions. This usually involves applying a lot of product to match the number of paint layers you are attempting to remove.

Two applications may be necessary for furniture covered with a thick layer of paint. You will then have to wait for the stripper to take effect (this can take a few minutes or a few hours) before scraping off the paint using a scraper tool that matches your surface in terms of both size and design.

  • Tools: paint brush, scraper tool, cloth, floor protection, stripper.
  • PPE: safety goggles, respiratory protection (important), protective gloves (recommended).

Stripping using caustic soda

Just like with chemical stripping, caustic soda must be used outdoors or in a well-ventilated room. The caustic soda should be applied using a paint brush; this should be done very carefully as this is a highly corrosive product. Apply the product according to the number of paint layers you have to strip and wait for it to take effect.

  • Tools: paint brush, scraper tool, cloth, floor protection, caustic soda.
  • PPE: safety goggles, respiratory protection, protective gloves (essential).

Heat stripping your furniture

Using a heat gun is an effective and environmentally friendly to strip furniture. Be sure to choose your nozzle to match the surface you are stripping. This process should not take too long. In fact, you can end up darkening the wood if it is heated too much. You will then have to finish the job by using a scraper tool suited to the surface you want to strip. A large, flat scraper can be use for flat surfaces while a pointed one is best for working into ridges, corners and so on.

  • Tools: heat gun, cloth, scraper.
  • PPE: safety goggles, respiratory protection, protective gloves.

How to remove wax

Removing wax from furniture is a similar process to chemical stripping, except for the fact that wax remover is generally a much less corrosive product. Apply a generous layer using a brush. After waiting from the wax remover to get to work, you simply need to wipe down your furniture using some steel wool, working in the direction of the wood grain. To deactivate the wax remover, you will have to apply some 95% rubbing alcohol with cotton wool. Awood brightener can then be applied, followed by more alcohol, if you plan to re-wax your furniture. Otherwise, you can simply sand down your furniture using fine grit sandpaper.

  • Tools: paint brush, steel wool, cotton wool, cloth, floor protection, wax remover, wood brightener, fine grit sandpaper, 95% rubbing alcohol.
  • PPE: safety goggles, respiratory protection, protective gloves.

Stripping by sanding


Metabo SXE 3150 230v 150mm Random Orbit Disc Sander

Using a sander to strip is perhaps the most popular technique, but it may not be the most suitable – especially if your paint is thick (you'll find your sandpaper quickly gets clogged up). You can sand using an orbital sander (ideal for curved surfaces), a random orbital sander (for large, flat surfaces) or a sanderwith a 1/4 sheet or triangular base (great for corners).

Sanding by hand

Depending on the size of your surface, you can also sand by hand using a sanding block. Any detailed parts should be sanded by hand or using a sander with a triangular base or a multi-purposeDremel-type tool. Whether you're working by hand or using a sander, you should always go from the coarsest to the finest grit and always move with the wood grain.
Sanding should be done after any stripping method and once you've finished, the piece should be dusted off with a blow gun or wiped with a cloth. There should be no dust left on your surfaces when you come to applying a new coat of varnish, lacquer or wood paint.
