Description
PRESENTATION
HYGIENIC PRIMER is a bi-component epoxy-resin with special additives in nano and microparticles, which give the primer ionizing and self-cleaning effects.
FEATURES
HYGIENIC PRIMER has been created in order to prepare floorings to the application of Hygienic Paint or Hygienic PAV and PAV AU in commercial sectors, hospitals, industrial and food sectors, meat processing places, cheese diaries, etc.
HYGIENIC PRIMER is used to prepare the surfaces to the treatment of the epoxy coating and floorings of the Hygienic line, in order to obtain the best adhesion between the two layers.
Moreover, when used for floorings, it waterproofs and blocks eventual water infiltrations which could compromise the adhesion of the epoxy mortar.
For vertical treatment before the application of Hygienic Paint, HYGIENIC PRIMER can be reinforced with 0.1 mm quartz according to the ratio 1/2 – 1/3, and then applied by roller.
As for treatment before the application of Hygienic PAV and PAV AU, HYGIENIC PRIMER can be reinforced with 0.3 mm quartz according to the ratio 1/2 – 1/3 and then applied by roller. Otherwise, while still fresh, 0.3 mm quartz can be spread on it to remove its surplus.
APPLICATION
a) Eliminate those parts which are not well anchored and all traces of oil and fats.
b) Check the support is flat and horizontal.
c) Check that the base is not humid and that it does not exude any water due to capillarity from underlying layers. Otherwise, apply a coat of HYGIENIC PRIMER, check there is no water infiltration, and remove the surplus quartz
as soon as you can walk on the surface.
d) If the surface is wet, apply a coat of HYGIENIC PRIMER with or without quartz, and follow the abovementioned indications.
e) Mix of HYGIENIC PRIMER: carefully mix 10 part of COMP. A with 5 parts of COMP. B. If you want to use quartz too, carefully mix it before application.
f) Any joints should be treated with HYGIENIC PRIMER to improve the adhesion of the elastic joint.
