Packing

2 & 10 litre

Area of Application

• It is effective for masonry structures as well as porous construction materials.
• for old structures, monuments and in areas having high water table.

Method of Application

• The area for grouting should be identified and marked for inserting the nozzles for the rising dampness
• The spacing of holes will depend upon the absorption capacity of the building material i.e. lower the absorption; lesser will be the spacing
• Using 12 mm to 15 mm diameter drill bit, drill holes at an inclination of 45o the extent of ½ to ¾ the wall thickness.
• The holes can be drilled either in the internal side or the external side of the wall.
• Dr. Fixit Dampfree creates a damp proofing course and therefore, should be injected in the lowest possible point almost touching the defective damp proofing course.
• The placing of the holes may be done at 300 mm c/c, vertically staggered. The vertical distance may be placed between 150 mm to 200 mm.
• Fix 10-12 mm diameter nozzles or as specified into the drilled holes. Place the nozzles in such a way, so as to leave sufficient gap at the inside end for inflow of the grouting liquid. Seal the nozzles inside the drilled holes with suitable material and allow it to set at least for a day before grouting.
• Depending upon the severity of dampness and the materials used in the wall & in its construction, Dr. Fixit Dampfree (as supplied) is diluted by 1 part with 5 parts of potable water.
• A hand pump sufficient to create pressure of approx.. 2 kg/cm2 must inject Dr. Fixit Dampfree through pressure grouting machine. Inject the diluted liquid by pumping till the point of return of liquid is felt.
• Allow it to remain for sometime before moving to the next nozzle.
• Observe the area for 24 hrs. Remove the extended / protruding nozzles and seal the holes with suitable compound.
• The treated areas should be washed thoroughly.

Precautions & Limitations

• Dr. Fixit Dampfree should be diluted depending upon the severity of the dampness. For advice, please consult Dr. Fixit.
• For damproofing to be fully effective, it generally takes 6 to 12 months.
• In view of alkaline nature, the material should not be handled or applied over aluminum or hot alloys.
• All old plaster and paint must be removed.
• The treated areas may be re-plastered using waterproofing additive or with suitable water repellent system.
• The consumption depends upon the absorption capacity of the building materials.
