When I took over my old farmhouse in 2016, whose foundation walls date back to 1888, I faced a massive structural task. An old house is a legacy of craftsmanship. Unfortunately, previous owners over the past decades didn’t always make the best decisions for the old masonry. Continue reading “Repointing Rubble Stone Masonry with Lime Mortar”
Sometimes it’s the everyday coincidences that give the decisive push for a new building project. During a bike ride through the neighborhood, Elisabeth recently noticed a small doll wardrobe that had been left outside a garden gate to be given away. The good piece was made of solid spruce wood and was completely untreated. Continue reading “Building a DIY Doll Bed”
When you renovate an old building, you know this moment: You enter a room on the ground floor that hasn’t been properly heated or ventilated for years. It smells earthy, slightly musty, and the cold literally creeps up your legs from below. During my restoration project, an old farmhouse from 1888 in Transylvania, I faced exactly this fundamental problem.

When I bought my old farmhouse from 1888 in Romania in 2016, I knew there would be a lot of work ahead of me. But only when I started knocking the layers of plaster off the walls did the true structural challenge of this project reveal itself. Beneath the crumbling plaster emerged a fascinating, yet building-physics-wise highly demanding structure: a solid mixed masonry consisting of hard, cool Saxon rubble stones and relatively soft, extremely absorbent field-fired bricks. Continue reading “Applying Lime Plaster to Mixed Masonry”
Anyone who has ever opened the massive, handcrafted softwood door of an old Saxon farmhouse knows the feeling. The heavy weight, the deep sound of the falling latch, and the inimitable patina of over a hundred years tell stories that no modern industrial door leaf could ever convey. When restoring historical buildings, I realize time and again: these doors are not just functional elements; they are the soul of the house. They were built by craftsmen who understood their trade from the ground up. Continue reading “Shaping and Restoring a Warped Historic Wooden Door”
Imagine standing in a room that has survived almost unchanged for well over a hundred years. The air smells of fine dust, dry wood, and the history of generations. That is exactly how I felt when I took over my house from 1888 and grasped the full dimensions of the ground floor for the first time.

When I was renovating my Transylvanian farm, it quickly became clear to me that I didn’t want to leave the property’s old water reserves unused. Continue reading “Using Well Water Sensibly: My Domestic Waterworks in the Transylvanian Farm”
An old well on your own property is much more than just a historical gem in the courtyard. It offers a tangible chance for a piece of independence and a self-sufficient water supply. But years or even decades of standstill leave their mark. Continue reading “The Revitalization of the Traditional Courtyard Well”
The hilly landscapes of Transylvania are characterized by a rugged, natural beauty. If you own or manage a property in this region, you are often faced with the challenge of securing the soil from slipping on slopes. Concrete walls are functional, but rarely blend harmoniously into the rural, historical picture and also seal valuable surfaces. A traditional and ecologically much more sensible alternative is the dry stone wall made of fieldstones. Continue reading “The Dry Stone Wall Made of Fieldstones”
When exposing old, hand-hewn oak beams in your home, you often face a major challenge: the beams have darkened significantly over the decades or centuries, they have often been painted – at best with easily removable limewash, at worst with stubborn oil paint – or they are simply extremely dusty. To fully bring out the rustic character of the hand-hewn beams indoors, they must be cleaned.
But which method is the right one for hand-hewn oak beams? In this article, I compare the most common approaches: low-pressure sandblasting, dry ice blasting, and mechanical sanding using a brush sander or a wire brush attachment for a drill or angle grinder.
Before you choose a method, there are steps and safety precautions that are absolutely essential. Old beams are often full of surprises and carry hidden risks.
Oak wood is beautiful, but its sanding dust is extremely dangerous and is considered carcinogenic. When sanding or blasting oak beams indoors, professional respiratory protection (at least an FFP3 mask) is absolutely mandatory. You must ensure powerful dust extraction (dust class M or H) and completely seal off adjacent living spaces to avoid endangering your health and that of your family.
My practical tip: Meticulously examine the wood for old, hand-forged nails, screws, or staples. A metal detector, more precisely a so-called pinpointer, does a great job here. Personally, I use the Garrett Pro-Pointer 2 for this task. Thanks to its handy shape, you can scan the beams centimeter by centimeter and accurately locate even deeply embedded metal parts that are often invisible from the outside.
Since it is extremely time-consuming to put down the tool after every find to pull the nail, I work in stages: Find the metal piece, make it visible, and simply mark the spot with a dot of spray paint. This way, you can complete the entire search first. In the second step, you take the tool and remove or countersink all marked nails in one go. In the third step, do a quick final check with the pinpointer. The sprayed paint will simply be removed during the subsequent cleaning (sanding or blasting) anyway. Take this preparation seriously: an overlooked nail can not only ruin your brush sander immediately, but it can also cause dangerous sparks or unsightly rust marks during blasting.
Hand-hewn wood is characterized by its uneven, wavy surface – the so-called axe marks. This is exactly the structure you want to preserve.
A brush sander with a nylon or brass brush is an excellent choice for DIY enthusiasts. The rotating brush adapts well to the unevenness of the hand-hewn wood without changing its basic shape. This gives you very good control over the material removal.
A very popular and inexpensive variant is the use of wire brush attachments (cup or wheel brushes) for the drill or angle grinder. This method is significantly more abrasive than the standard brush sander. This is particularly advantageous if you need to remove stubborn oil paint. In addition, narrow wire brushes are excellent for reaching into large cracks and deep joints in the wood. But beware: the rotating wire bristles can be extremely aggressive and leave deep grooves in the wood if too much pressure is applied.
In low-pressure blasting, a fine abrasive (such as glass beads, walnut shells, or special sand) is blown onto the wood with relatively low pressure. This method cleans deep into the tightest crevices and wormholes that you would never reach with a brush. The result is often very uniform.
A particularly gentle premium alternative is dry ice blasting. Here, frozen CO2 pellets are shot at the wood, blasting away dirt or stubborn oil paint upon impact, and then immediately dissolving into gas. No abrasive is left behind, only the removed dirt. This method is extremely gentle on the historical wood structure, but usually more expensive as it is almost always carried out by professionals.
Mechanical Sanding (Brush Sander & Wire Brush): Lower initial costs (approx. 100 to 300 euros, wire brush attachments are even cheaper), ideal for smaller areas and individual rooms. Good for limewash, but soft brushes smear quickly with tough oil paint, which is where the wire brush shows its strengths. However, the time required is enormous, and the work is very physically demanding.
Low-Pressure & Dry Ice Blasting: High costs for renting a compressor and blasting equipment or hiring a specialist company. However, these methods save an extreme amount of time for large areas and thick layers of paint.
Warning: Proceed carefully with all methods! Too aggressive removal (especially with coarse wire brushes) destroys the historical patina and the unique axe marks of the oak beams. Once sanded away, this historical character is irretrievably lost.
To ensure your project is a success, you should proceed systematically:
