Flowcrete Flowfast 101 Standard Primer Clear 20kg MMA Concrete Primer
Flowfast 101 Standard Primer
Flowfast 101 Standard Primer is a low-viscosity, colourless, 2-component reactive resin based on methyl methacrylate (MMA) designed for concrete and cementitious substrates. It will bond to surface dry substrates that have a Relative Humidity up to 95% (to BS 8204).
Uses
Flowfast 101 Standard Primer is used as a general prime coat for Flowfast floor coatings, including Deckshield Rapide and Flowfast resin toppings, on concrete, screeds and wood. It is normally used as supplied but may be thinned with Flowfast 407 VR to increase the penetration into certain types of cementitious substrates. For information on related products, please see the respective data sheets.
Note: We strongly recommend that with all Flowfast primers, curing and adhesion tests are conducted on the substrate prior to general use on site.
