Features & Benefits

• For professional use only
• Special two-component formulate developed in the MAPEI R&D laboratories
• Cures in 30 minutes
• When used with membranes from the Purtop range allows the waterproofing system to be applied in just one day
• Easy to apply with a roller, trowel or rake

Surface Preparation

• Surfaces to be treated with the product must be clean and sound with no crumbling or detached areas
• The level of moisture in the substrate must be a maximum of 4% and there must be no capillary rising damp
• Prepare surfaces with a suitable mechanical process (e.g. shot-blasting) to remove all traces of dirt, cement laitance and crumbling or detached areas and to create a slightly rough, absorbent surface
• Before applying Primer FT, remove any traces of dust from the surface with a vacuum cleaner
• Mix the two components that make up Primer FT together just before use with a suitable electric mixer at low speed to prevent entraining air into the mix, for around 2 minutes, or until thoroughly blended

Application

• Apply Primer FT with a roller, trowel or rake on the substrate prepared as specified, in one or two coats depending on its condition, so that it is completely saturated and all surface porosity is sealed
• If the maximum recoat time is exceeded, apply another coat of primer before applying the membrane from the Purtop range
• Consumption about 0.3 kg/m² per coat depending on the condition of the substrate (roughness, absorbency, temperature, etc.)
• Clean tools used to prepare and apply Primer FT immediately after use with thinners. Once hardened, the product may only be removed mechanically

Limitations

• Do not apply Primer FT on substrates with rising damp or with more than 4% moisture content
• Do not dilute Primer FT with solvents or water
• Do not apply Primer FT on dusty, crumbling or weak substrates
• Do not apply Primer FT on substrates with oil or grease stains or that are dirty in general
• Do not apply Primer FT on substrates that have not been prepared as specified
• Do not expose the mixed product to sources of heat
• The temperature of the substrate must be at least 3°C higher than the dew-point temperature
