A. Cement Floors. ·The mortar should have a humidity level less than 2% MC, following the Magnesium method. When using artificial drying methods to dry the surface, this can cause the lower layers to retain moisture which will, in time, rise to the surface. You should allocate a sufficient period of time for drying out before undertaking any work. ·The drying time of the base floor will depend on the thickness and atmospheric conditions of the area. As a guide, you can estimate that in conditions of 20ºC and 50% humidity, drying time can be calculated using the following formula: t = 2s2 where “t” is time (in days) and “s” is the tickness of the base floor (in centimetres).
B.··On base-floors where wooden flooring has already been fitted, we recommend that you remove some of the perimeter of the old flooring to allow proper ventillation.· The new flooring should be laid at right angles with the old flooring, and never in the same direction.
G. ·If the foundation floor is directly over the subsoil and in a glazed area, exposed to sunshine, we recommend that you fit sheets of 10 mm expanded polythene with a density of at least 35 kg/m3 in order to protect the product from sudden and successive temperature changes, due to the cooling caused by the humidity of the base-floor and the heat from the sun.
DUE TO ISOLATION, ACOUSTIC AND ANTI MOISTURE. ALWAYS PLACE THE UNDERLAY .
We recommend that you lay the flooring in the same direction as the main source of light
Use separating wedges to make sure that a 10 mm gap is left between the walls and entire perimeter of the flooring. This gap will be hidden once the skirting board and profiles have been fitted, and will give the product the space necessary for expansion and contraction..
In doorways, a 30mm gap should be left (10 mm for the width of the product and 10 mm for each length) where the expansion profiles will be placed to separate the different rooms..
-FIRST BOARD OF THE SECOND ROW: Use a section of the board you have just cut for the final board of the last row to start the next row. This board must be at least 30cm long. If it is too short, start the row with a new board, cut to 1/3 its usual length. Always make sure that the joints of the first and last boards are staggered by at least 30 cm.
-CONTINUE LAYING THE FLOORING: 1) Place the next board flat, parallel to the board of the adjoining row, raise the panel at an angle of approximately 15º, push forwards and downwards lightly and the boards should automatically interlock.
2) Place the short end of the next board opposite the board just installed, push forwards and downwards lightly. Make sure that it is close to the adjoining board, and proceed to lock it together with the previous piece.
3) Lift the board, creating an angle of approximately 15º (along with the previous board of the same row), push lightly forwards and downwards so that the boards lock into the length sides of the previous row.
- TO LAY THE FINAL ROW: measure and cut the board. Leave a 10mm gap with the wall for expansion.
Finfloor and Purefloor surface is protected to give a long life and high wear resistance. It's a finished product, however, we must take into account a number of recommendations and instructions for maintenance and cleaning.
-The ideal conditions for avoiding changes in the board’s dimensions are 50-70% relative humidity and approximately 20ºC. If neccessary, use a dehumidifier.
-The use of doormats at exterior door entrances is recommended in order to prevent dirt, dust, gravel, etc... coming in from the street.
-The ideal conditions for avoiding changes in the board’s dimensions are 50-70% relative humidity and approximately 20ºC. If neccessary, use a dehumidifier.
-Special care should be taken in areas of domestic animals. (Urine can damage the laminate flooring).
