surface is treated with products that create a protective film and remains spotted, with marks of cloudiness here and there.
This happens when the manual installer rubs with a generally circular movement on the surface that is so vigorous that its heats up the surface and causes the area in ques- tion to cloud. Laboratory analysis is some- times performed on samples of material for infrared inspection
that easily confirms the presence or absence of calcium carbonates. Oil-finished floors al- so frequently present problems caused by the presence of bond- ing adhesive.
As shown in the photo below, for example, af- ter the presence of car- bonates in the grain was confirmed, the at- tempt to remove the blemish only led to the creation of another flaw. Rubbing only re- sulted in additional light-colored marking, as two different types of damage were the re- sult of two different er- rors in working.
In conclusion
After all the inspec- tions conduced, we can say that the amount of time allowed to pass from when laying ad- hesive accidentally drips onto the floor un- til the moment the at- tempt is made to re- move it certainly plays a big part in its success. The concentration of inert fillers such as cal- cium carbonate in the chemical adhesives used to bond wood floors in the pores of the wood, especially in planks with Stan- dard tangential grain is the prime cause of complaint. Clumsy at- tempts at removing
glue residue only spread it more widely over the wood surface. If the floor has been pro- vided with particular brushing treatment, the problem is even worse. The color of the wood also makes a greater or lesser contri- bution to the extent of the problem. When the surface is in its natural state, the visual impact will probably be insignificant, even if the anomaly is there just the same. s
