Floorcoat has years of industry experience when it comes to timber flooring. Our services include timber floor sanding, floor preparation, application of protective coatings, and ongoing upkeep and maintenance.

 

Timber Floor Sanding

Timber floor sanding is done with specialised sanding machines. The floor is then finished with the desired protective coating; oil or polyurethane etc.

What is Timber Floor Sanding?

Wooden floors are sanded down with a large belt or drum sanding equipment. The majority of the material is removed by these sanders. The areas where the large sanders cannot reach, such as edges, corners, and stairs, are sanded by an edger/hand tool. A finishing machine is then used for the final floor sanding.

First stage of floor sanding is the preparation

Preparation is the first stage of the floor sanding process. All nails which protrude above the boards are punched down. Nails can severely damage the sanding machines which are being used. Staples or tacks used to fasten previous coverings (if any) have to be removed to reduce the possibility of damage. Adhesives that have been used to secure floor coverings will have to be removed. These adhesives can clog the papers and running gear of the machines used, and some can even make sanding impossible. Other machinery like grinders may need to be used.

Second stage of wooden floor sanding

Sanding begins after the floor is properly prepared. The first cut is done with coarse-grit papers (typically 16 to 40 grit) to remove old coatings and to make the floor flat. The differences in height between the boards are removed. The areas which cannot be reached by the large sanders are sanded by an edger. If filling of holes or boards is desired this is the stage where it would usually do. The process is then repeated for the second cut using finer sandpaper, typically 60 to 120 grit. A disking finishing machine is then used to create the final finish.

Third and final stage of floor sanding, the coating

The sanded floor can be coated with polyurethane, oils, stain, or other sealants to give the end finished result and to protect the floor.

The usual process is the use of polyurethane to bring out the best in your floor sanding. 3-4 coats are required to give great results with disking and cleaning between each stage. Different levels of sheen are available, from low sheen to full gloss. Scroll down this page to read more about choosing the right coating.

Looking after your sanded floors

Maintenance coats will be required around 2-5 years later. These are crucial to the long life of the floor, known in the industry as a ‘reglaze’, cost is minimal. If proper maintenance is not kept then these coatings will be compromised, which will lead to a re-sand of the entire floor. There are only 6-8 sands on a floor before it needs to be replaced.

General cleaning is best performed by a micro-fiber static mop for day-to-day cleaning. This keeps the dust levels down which prevents premature wear and tear on the top coat. Weekly or monthly cleaning is best done by washing the floor. Please check up on what is best to clean your floors before cleaning with something you have found from the supermarket.

Choosing the Right Polyurethane for Your Timber Floors

To keep your timber flooring looking its best it’s important to select the correct polyurethane – this can seem a daunting task and one we are often asked at Floorcoat NZ. Polyurethane is a type of finish applied to timber and hardwood flooring. Once applied it helps protect, rejuvenate, enhance, and maintain the natural beauty of the timber. It comes in both solvent and water-based types.

Think of it as a synthetic resin coating that dries to a hard and durable finish.

Both solvent-based polyurethane and water-based polyurethane have their pros and cons, and the best choice will depend on your specific needs and preferences.

We’ve compared the two types to help make your choice easier. Please click on the options below for more information.

SOLVENT BASED POLYURETHANE - Click for more info.

Solvent-based, or “oil-based” polyurethane is the traditional type of finish – they’ve been around for decades.

Solvent-based polyurethane finishes are high in VOCs (volatile organic compounds) and have a strong odour when applied which can last for some weeks. You’ll need good ventilation during and after the application.

So, what are VOCs? Volatile organic compounds are chemicals released into the air or atmosphere as a product dries and cures. VOCs are used in many household products like paints, varnishes, and cleaning products. The lower the VOCs – the healthier it is for you and the planet.

Solvent-Based Polyurethane Products:

  • Solvent-based finishes are naturally slightly yellow and will darken in time to a slight amber hue.
  • Any sections of flooring protected from the daylight will maintain their original colour, while any sections exposed to the daylight will yellow – think under carpets or under furniture. If rugs or furniture are re-arranged or removed in the future, these areas will have a distinct colour difference from the areas exposed to daylight.
  • Its application brings up and enhances the colour of the timber.
  • It’s very durable – consider it for high-traffic areas or those that require a high-shine finish. Maintenance recoats won’t be as often.
  • Available in gloss, semi-gloss, and satin finishes. It can be very glossy when compared to water-based products.
  • The product contains harsh chemicals which give off fumes and odours.
  • With high scratch resistance properties, it is considered the most durable finish.
  • One or two coats per day can be applied. You can walk on the floors within 24 hours and move furniture back into the room within 72 hours, they take longer to dry than water-based.
  • These finishes are not able to be recoated. This means that the next time when your floor needs to be redone you will need to fully re-sand and re-polish your floors.

WATER BASED POLYURETHANE - Click for more info.

There are many advantages to selecting water-based polyurethane products for your floors. Water-based polyurethanes are considered a better choice for the environment and for the health of your family and pets because they contain fewer harmful compounds (VOCs) than solvent-based products.

These products are popular because of their safer application, and quick drying properties, and they don’t emit strong fumes while curing or hardening. When the finish is applied the water evaporates and the polyurethane forms a film. Once it hardens the finish is waterproof and durable. The look and protection of your floors are like that of a traditional finish.

Water-Based Polyurethane Products:

  • Are low in odour and VOCs, give off fewer fumes during application, an eco-friendly option
  • Are easy to maintain and apply
  • Will maintain the natural colour of the timber
  • Are available in different sheen levels – gloss, semi-gloss, satin and matt finishes
  • Are highly durable
  • Do not yellow over time or with exposure to sunlight
  • Has good scratch resistance, and produces a clear finish that can easily be changed or repaired down the track.
  • Up to 3 coats can be applied in a day. Flooring can be used 24 hours after the final coat is applied, it is faster drying than solvent-based.
  •  These finishes can be re-coated which means they will save you money in the long term. You may simply apply another coat of the same product on top of the existing coating.

In general, solvent-based polyurethane is known for its durability and longevity, while water-based polyurethane is known for its quick drying time, environmental benefits, and low odour.

We recommend vacating your house for at least 24 hours following the application of any polyurethane finish and ventilate well on your return.

When choosing what type of polyurethane to use, a solvent-based option is the cheaper alternative initially. Upgrading to a water-based finish is better for your health and the environment and although will add to the initial outlay it will save you money in the longer term.
