Self-cleaning & deodorizing cool paint
Inspired by the Japanese word Kirei that simultaneously means clean and beautiful, SurfaPaint Kirei is a functional and intelligent paint that has the ability to self-cleaning, remaining as new. Dirt, bacteria, fungi and mould are decomposed to carbon dioxide and inorganic material just by the energy of light.
SurfaPaint Kirei is a photocatalytc cool paint with self-cleaning propertes. By harnessing the power of surrounding light, ttanium dioxide nanopartcles decompose organic substances. When applied on exterior surfaces SurfaPaint Kirei decomposes organic stains, polluton and prevents mould growth and reflects more than 94% of the incident InfraRed (IR) radiaton, saving energy and reducing building heatng/cooling costs. Reflectance values are further enhanced by the photocatalytc, self-cleaning effect and remain unchanged for a longer period of tme when compared to a conventonal paint as it is a weather resistant paint with exceptonal coverage, opacity and resistance to UV radiaton. Therefore, the original, fresh look of a newly painted surface remains long afer applicaton.
When SurfaPaint Kirei is applied on interior surfaces, artiﬁcial light activates it and sterilizes airborne or surface-bound microorganisms, deodorizes and improves indoor air quality. The paint is white and can be tinted as pal colour (only with inorganic dyes). SurfaPaint Kirei is a Cool Coating, certified by the European Cool Roofs Council (ECRC).
SurfaPaint Kirei can be applied Exterior or interior wall surfaces: masonry, concrete, plaster, drywalls, and wherever emulsion paints are applied.
Applicability: SurfaPaint Kirei can be applied directly on interior or exterior wall surfaces (masonry, concrete, plaster, drywalls), and wherever water based, acrylic paints are applied. New substrates from cement or masonry should have cured for more than 3-4 weeks before primer application. For better results apply SurfaMix P as a primer. Adverse conditions during or immediately after application may aﬀect the coating's properties.Contact NanoPhos () for instructions on industrially adding SurfaPaint Kirei Paste to conventional paints or refer to the Product Data Sheet herein.
Preparation: Ensure all surfaces are clean and dry prior to application. Remove any dust and dirt.
Application note: Stir well before application. Do not dilute for bridging gaps and hairline cracks of up to 0,5 mm. For cracks bigger that 1mm, ﬁll the gap with a suitable putty. If thinning is required add up to 10% water by volume. Application temperature should be between 8 - 35oC. Apply 2-3 even coats using a good quality brush, roller or by spraying with a tip of a diameter 1,4mm or more. Do not over-brush. Ensure corners and edges are adequately covered. Additional coats should be applied 4-6 hours after the previous application.
Spreading Rate: 10-12 m²/L.
Drying Time: Typically 1 hour depending upon coat thickness. Low temperatures and high humidity will lengthen drying times.
