Useful tips

consumption on the package may be for us only a guide - minimum.Manufacturers determine the numerical value of the parameter is calculated on the upscale professional plasterer.If the work is done "mere mortals", the applied layer so thin, it is implied, will never succeed. Practice has shown, as determined purchase amount, it is necessary to increase the composition of the recommended flow rate of not less than 15%.

must also specify the release date and mix.As with any such composition, "Rotband" is characterized by a period of fitness.

What is the meaning?In the production of the stamp "fills" the machine, and time changes constantly above it.And if it is on all packages is the same, there is no doubt - the warehouse of finished products went to "Uncle Bob" and stamped "left and right" indiscriminately.

on bags licensed manufacturers certainly put proprietary hologram.And it is necessary to pay attention to.
