Burgundian "dalles"

Burgundian “dalles”
Antique Burgundian limestone/sandstone “dalles”, or sandstone “dalles” create a rustic atmosphere in your house. Originally, they were laid in free-length widths. However, Burgundian “dalles” may also be presorted in equal widths and laid in strips. Burgundian “dalles” or sandstone “dalles” are available in different sandstone tints, depending on the region they come from.

Origin of Burgundian “dalles”
Antique and new Burgundian “dalles” come from France, more precisely from the Burgundy region. The region has various stone quarries. The Burgundian “dalles” may be white, yellow, cream or light brown. Some are softer or harder than others. Burgundian “dalles” should be distinguished from antique bluestone “dalles”. The latter are made of Belgian bluestone, a harder type of stone, also known as freestone. Bluestone “dalles” are grey, whereas Burgundian “dalles” are slightly cream-coloured or sandy-coloured.

Recovery of Burgundian “dalles”
Antique and new Burgundian French stone or Belgian bluestone “dalles” are on sale at the building materials antique dealer ‘t Achterhuis in Udenhout. ‘t Achterhuis has either recovered or bought them from French and Belgian knackers. The old “dalles” are becoming scarcer and are more expensive than the new ones because they need to be detached and re-sorted. Since there are still stone quarries in France, new models are also available. In many cases, the Burgundian “dalles” are distressed to give them an old, antique or rustic appearance. Sometimes it is hard to detect the differences, but ‘t Achterhuis may provide expert advice if desired. 

Antique staircases

If you would like to build a house and incorporate old elements, it is advisable to start off early. An antique staircase, for instance, needs to be fully measured and sketched in. Imagine finding the antique staircase of your dreams and realising afterwards that it does not fit and that it cannot be used. An antique staircase can be built in in the same way as your current staircase.

Restoration of antique staircases
An antique staircase can be restored quite easily. Generally, the antique staircase is fully disassembled, broken pieces are replaced and all components are cleaned separately. Afterwards all components are glued together again. The restoration process gives the antique staircase a new look.

Are antique staircases more expensive?
Antique staircases are not necessarily more expensive than new ones. If you compare the price of an antique staircase with the price of a new similar model, you will be surprised at the difference. Few people know that the difference in price is that striking. An antique staircase is not only less expensive, but also gives your entrance hall a unique touch.  

Background of cast-iron clawfoot bathtubs

Cast-iron clawfoot bathtubs have been around for a long time. Bathing used to be a hygienic necessity, but this changed towards the end of the nineteenth century due to a number of technical inventions such as sewerage, gas and the water supply system.
The first bathtubs were made of brass, afterwards of zinc. Later, cast-iron clawfoot bathtubs were created.

New cast-iron clawfoot bathtubs
We have various new cast-iron clawfoot bathtubs in stock. They are equipped with an enamelled coat on the inside. Contrary to traditional beliefs, the water remains warm for a long time when the cast iron has warmed up. The exterior may be painted in any colour. This applies to all cast-iron clawfoot bathtubs, including the “Marseilles”, “Nice”, “Bordeaux” and “Paris” models. We also have cast-iron bathtubs without feet: the beautiful, taut “Monaco” bathtub. We kindly invite you to visit our show room.

Rustic building

Rustic building is becoming increasingly popular. The term is employed when a new house is built using old, antique and rustic building materials. This creates the effect of building an old house: a rustic appearance combined with present-day comfort. Rustic building fans can go a long way in using old, antique and rustic building materials.

Rustic building: both inside and outside

Rustic building can be applied both inside and outside. You can build the outside with facing bricks such as Ijssel stones, brick baked in open ovens, Waal brick, etc. and use an old porch with an antique front door. You can also use recovered wall clamps and/or old thresholds and windowsills. Inside old oak beams, old boarded or tiled floors, antique fireplaces, old sinks, old inner doors, antique white tiles, etc. can be employed. Rustic building does not imply that you should solely incorporate old and recovered materials. Rustic or old materials can also be integrated perfectly.

Rustic building: high-quality materials?

We can reassure those who doubt whether the old materials employed for rustic building are strong enough to be reused. These (recovered) materials are given a second life through rustic building. They have already proved their quality and solidity in an earlier life. “These bricks look porous,” some people say. Actually, they are very solid. They have already been used in another building, have survived demolition, have been chipped with a chopping-knife or hatchet and are still intact. This also applies to antique tiled and boarded floors. Therefore, we can guarantee you that the old and antique materials offered for sale for rustic building are as solid as new ones. Obviously, they look different, aged. But that is what rustic building fans are looking for. 

Laying and Maintenance Advice

How to install your Achterhuis tile floor 

Tiles can be fixed onto most floors. The surface must be properly prepared, suitably level, sound, clean, dry, and free of dust, grease or any loose material.

Old, and antique tiles are usually put "under the wire", in cement.

So the top the tiles against the bottom of a wire to keep the differences in thickness underneath and the surface straight.

Some could possibly be put in special glue/thick-bed adhesive when the differences are small. One example of such product is Strasser Egalfix Plus.

All tiles should be well mixed before instalment. Installing means all parties are satisfied with the colour and quality.


Usually a smaller tile will be a little bit less thick than a bigger one. With under floor heating one should take the height of the tubes into consideration.

Before you put in the grout/joints make sure the tiles are wet as otherwise the joint will dry too quickly making it possible they crack. Especially antique terracotta tiles and other porous tiles will drain the water out of the grout/joint if not wet.

To keep the tiles clean it's recommended to do small areas at a time and carefully sponge them with clean water to prevent the cement of attaching to the tile too much.


Work height = total thickness of tile + cement, for smaller tiles ± 4cm and for bigger ones ± 5cm.

Grout joint about 10 to 15mm for 'rougher' tiles and about 5mm for straight, neat ones.

The size of the tiles, when calculating the amount per m², is measured including the grout joint.

If the desire is to install the tiles with smaller grout joints we recommend to install them "in a running bond" (also known as brick- or offset pattern). With some extra sorting it's possible to even put terracotta tiles with smaller grout joints but remember that you'll need more tiles thus more m².


How to treat your tile floor

1) After the tiles are installed they must be cleaned carefully but thoroughly before you seal them or treat them with a natural soap (this depends on the material). Don't cover the tiles as they need to dry prior to sealing them.

2) After the tiles are cleaned you'll need to wait until the tiles are 100% dry. You can easily check this by putting a piece of plastic on the floor at night and check for condense in the morning. When the tiles are completely dry you can seal them with pure Superfix (liquid wax, available at ‘t Achterhuis). For Belgian bluestone you normally just mob them with a natural soap, see bottom text.
The Superfix should be used only on a dry, clean floor. (The best result is obtained by a good even distribution) Depending on the porosity of the tile you might need to apply a second or even a third layer. Please make sure there's 8 hours between every layer. Afterwards Superfix is also usable as a maintenance substance to upkeep the protection. Just put a coffee cup full of this Superfix in a bucket of clean water and mob the floor with it. For cleaning you best use a natural soap. Superfix will provide the floor with the satin gloss again where it's worn out.

3) When many years have past and you want to give the floor a big overhaul you could strip it with a good cleaner and reapply the Superfix.

4) When the floor is extra porous (like antique Burgundy dalles or some terracotta tiles) you best start with one or two layers of a more permanent saturation substance like PN before you put layers of Superfix on it.

5) For really hard stones like Belgian bluestone you best use our abbey/monastery soap or dilute Superfix with water. Don't put Superfix on such tiles pure.
Abbey/monastery soap is cleaning and protection in one.


Laying and maintenance advice wooden floors


When receiving the wooden boards it sometimes is hard to imagine that this

will make for the same floor as seen here in our showrooms.

If desired we could introduce an installer of wooden floors or you could contact

us for information regarding instalment of your floor.

For treatment of the surface you can choose a lot of different methods these

days. Oil, wax, lacquer or other coatings are all possible. Some coatings are

prepared so that you can clean your wooden floor with a moist cloth or mob

making it really easy to keep it clean.


Only install a wooden floor in a dry room (measure this with a hygrometer).

You best put the wooden boards (back) in plastic when it won't be installed

immediately. All cementfloors should be measured upfront. Residual moisture

must not be over 2%.

Possible ways of installation
1. Permanent: glued on a 12mm thick underfloor of chipboard. Preferably use

    a PU-glue and nails.

2. Floating: loose on a suitable under floor.

Floor boards that come already treated have no need to be sanded. The other

floor boards should be sanded before they are colored/treated.

By sanding the floor you remove all the dirt and open fibers. This way the surface

gets a good preparation for the treatment of oil, wax, lacquer etc.

Usually sanding is done in different fases. First with a large grain, then with a

finer one.


Rules of thumb for sanding
1.            Sand as much as possible in the direction of the wood grain.

2.            When in doubt about the coarseness of the sand paper, opt for a fine rather than a rough

                coarse grit. Start with grain 40, then grain 80 and if needed end with grain 120.


Colours of the floor
First, always do a test on a sample until the desired result is achieved.


1.            Can be removed with a damp cloth.

2.            Silk gloss, matt or extra matt.

3.            For example trea-lyx parquet lacquer or 2 component PU lacquer.
Lacquering with the roller:

Use a roller on a long handle and a special roller tray. Always start with the shortest     

side of the room floor and always start from the same side. Apply the lacquer at a perpendicular angle on the wood grain direction and roll in the same direction as the wood grain. Multiple layers are necessary for a good result. Consumption ± 1 litre on 10m².

Wax or oil:
1.            Easy to update (e.g. with polisher or cloth).

2.            In different colour shades.
