I cannot not to react to this subjectbecause there is wider and wider price gap for sanding and painting of the floor on our market. From what I could find out there is the cheapest price for sanding and painting of the floor about 6,- € / m2 and the most expensive price I could found is 15,- € / m2. The price gap is more than 150%, isn’t that weird??? So let’s talk about this a little more.
Of course that for Slovak customer is price the priority and on contrary to all, 6,- € / m2 is price without competition. If you will decide for this variation let’s be honest then, you cannot expect miracles. The sanding of the parquet can go well but what I guarantee you is that only the cheapest protective paints available will be used in this case. What I found out last time thanks to my customer is that at his place was used just normal glazing paint and only in two layers. The main protective painting during the renovation of the floors is used for stopping the absorbency of the wood and to make the structure of the wood more apparent. This cheap basic paint do not have such fullness (or better said, filling ability) as the professional parquet protective paints have. So such cheap paint won’t create desired thickness of the protective layer. A floor painted in this way won’t have such utility attributes (i.e. abrasion resistance) as would floor painted with professional color has (1x main layer + 2x upper layer of paint). I can assure you from the experience that usage of 2 layers of basic glazing paint will not create such a thick protection as would one layer of professional paint that is designed as protective paint for parquet.
At the customer mentioned above I noticed that even the sanding was not as right as it should be. On the surface of the floor one could see the marks from the bands from the band-abrasive machine, which were visible in the reflection of the light falling on the floor. Possibly the worker who did this job was cheap when it comes to saving of the abrasive bands and he used the sanding papers that did already sand kilometers of floors before, or he ended the sanding with sanding paper with a thicker grading or he did not finish the polishing with the disc sander equipped with abrasive net (usually grading of 100-120).
One more jewel from my personal experience. Sometimes can someone bring protective paints on the dissolvent or amino acidic basis, etc. I am not saying those are the bad kind of paints, but for housing purposes I don’t recommend them. Mostly because of their long lasting stench even after drying and hardening and if you have small children it is especially not suitable. Last time I worked with such paint at one of my customers place (he desired to use such paint), he later regretted that he did not take my advice because his apartment smelled a bit bad even after one month.
The paints on dissolving basis are more suitable for big gyms used in schools or public places (because the renovation in school gyms are usually made during school holidays and the air will be cleared out there during the holiday period). In public places people tend to not stay so long, thus they don’t inhale the exhalation with such intensity.
Finally I would like to summarize some advices about what you should ask if you are looking for a real professional in the field of flooring renovation:
- What types of abrasive machines is he using (band-abrasive for the surface, side-abrasive machine for the sides and polishing machine for the finishing of the surface), are the machines of Professional grade and do they have vacuuming implemented
- If he is using professional protective colors (if you want ones without smell and ecological you should ask for paints on water basis and if you don’t mind this then ask for dissolving basis colors)
- If he is painting standardly with one basic layer and then 2 upper layer with professional protective colors
- If he is doing an „in between sanding“ after painting of the first upper layer (during the painting there will always be created a kind of wooden hair which will make the floor rough on touch- with the „in between sanding“ you will achieve a soft surface of your painted floor)
In the end of this article I suggest also these control questions which every experienced flooring professional can answer with no problems:
- When is the floor able to walk on after painting
- When does the protective paint final toughness and is ready for the burden to be putted upon it
- How can one take care of such painted floor
- If the manufacturer of the color offers also some products aimed for taking care of the floor painted by their color
- Will the color be mat, semi-mat or bright
- If there is possibility to pay more for higher grade of the color with better endurance
- If there is possibility of sealing the small crevices with the putty
- Will the putty hold in the gaps or can it crack and get out of the crevice
Ask more companies with these questions and I guarantee you that you will choose the right flooring professional and not regret your investment.
