1 Atro Mosaic standard matt, Atro Mosaic standard goss, Atro Mosaic vertica matt and Atro Mosaic vertica goss Muti-coour decorative foor finish system Nomina thickness 1-1.5mm Technica and instaation data sheet September 2016 Product description FeRFA type 4 Atro Mosaic is a sovent-free epoxy resin combination system that encapsuates decorative acryic fakes in Atro Tect standard cear epoxy resin. Seect from two distincty different systems, one offering a vibrant gossy finish the other a subte gazed smooth appearance. Atro Mosaic standard goss - Uses a base of high buid cooured epoxy, Atro Tect standard cooured with a fu scatter of muticooured paint fakes seaed with two coats of Atro Tect standard cear to eave a textured high goss finish. Atro Mosaic matt - Atro Tect standard cooured with a fu scatter of muti cooured paint fakes seaed with three coats of Atro Tect standard cear and a fina sea of Atro Sea water based matt, to eave a gazed matt finish. Standard coours Atro Mosaic variants are avaiabe in a range of 15 standard coours with options for bespoke coours. Sustainabiity Atro s steps to sustainabiity program seeks to optimise our performance with respect to the panet s resources. Pease refer to for further information. Typica areas of use Medium duty areas Communa areas Wakways Corridors Reception areas Atria Advantages Low odour Good chemica resistance Good abrasion resistance (to genera ight traffic) Optiona finishes Ease of ceaning Chemica Resistance Atro Mosaic variants offer good resistance to a range of commony used chemicas. However, premature or proonged contact with chemicas (incuding water) during the curing process may give rise to discoouration, staining and variation in goss. In a cases of chemica spiage, it is essentia that the spiage be immediatey removed and the surface washed down with cean water, removing water by wet vacuum after operation. Athough some chemicas may cause discoouration, this may not affect the durabiity and integrity of the resin coating. Pease refer to Atro, and FeRFA Guidance Note No.3 for further information.

Priming of porous substrates wi improve the coverage rates. Pae coours may require additiona coats to cover a dark substrate. Athough stringent quaity assurance processes are empoyed, when coour consistency is essentia a singe batch must aways be used where possibe. Storage Ensure that the product is received in good order and store in a dry, frost-free environment, ideay between 15 C and 20 C for at east three days before aying. Excessivey high and ow storage temperatures wi affect the aying performance of the product. Suitabe substrates The Atro Mosaic variants can be appied to a variety of substrates incuding, but not imited to, concrete, poymermodified cementitious screeds and terrazzo. For a proprietary subfoor systems refer to the manufacturer for recommendations and seek further guidance from Atro. FeRFA, The Resin Federation, does not recommend Cacium Suphate, Anhydrite or Hemi-hydrite screeds for overayment with synthetic resin surfaces. Substrate requirements Substrates shoud be dry, structuray sound and free from contamination, friabe materias or aitance which may affect either the adhesion or penetration of the resin system. A residues of od paint coatings and dust must be removed. Substrates to achieve 26N/mm² compressive strength (BS EN ) and surface tensie strength 1.5N/mm² (BS EN ). Substrates must incude an effective damp-proof membrane and contain residua moisture not greater than 5% by weight (75% RH) to BS 8203:2001 (see Atro Proof for instaations above 75% R.H.). Variabe porosity and profie of the substrate wi affect both coverage rates and fina appearance. Pease consut Atro or FeRFA Guide to the Specification and Appication of Synthetic Resin Fooring for further information.

3 Substrate preparation Surface preparation is the most vita aspect of resin fooring appication. Inadequate preparation wi ead to oss of adhesion and faiure. The substrate in question wi dictate the method of preparation. In the case of a concrete foor, preparation by dust encosed diamond foor grinder may be appropriate, or if of a sufficient area for economic reasons, shoud be ighty shot basted to eave a textured surface free from contamination. If the foor has been treated with a cementitious surface improver, then the surface shoud be prepared in accordance with the manufacturer s recommendations, or abraded with an STR machine foowed by thorough vacuuming. Treatment of oca repairs such as cracks and hoes, improvement or modification of eves and remova of high spots, shoud be undertaken prior to the fooring instaation. Thin coatings wi refect the surface texture. High spots may ead to oca premature wear. Excessive profies as a resut of inappropriate surface preparation may significanty affect appication, coverage and performance. Pease consut Atro or FeRFA s Guide to the Specification and Appication of Synthetic Resin Fooring for further guidance. Panning Before proceeding with the instaation, carefu consideration shoud determine the best way of instaing the Atro system, and optimise the open time of the product (ie minimise the distance between mixing and aying). It is best to aso consider the effect of externa infuences on the fina instaation (i.e. direction of ight from windows etc). Time spent at this stage wi be invauabe towards the success of your instaation. Appication The foowing appication guide is based on aboratory and simuated site conditions. However, when instaations conditions differ appreciaby from those detaied by Atro, the performance characteristics of both mixing and aying may not be as expected. To achieve the best resuts at a times pease endeavour to estabish the correct conditions which in turn wi aow the materias to be aid effectivey, and meet your customer s expectations. Instaation conditions Appy in we ventiated areas. Both the sab and air temperature shoud be greater than 10 C and rising, up to 25 C. It is not advisabe to mix and ay epoxy resin products outside the range 10 C to 25 C. Ambient conditions shoud be maintained at east 3 C above dew point or beow 75% RH during the initia stages of cure. At site temperatures beow 10 C cure times wi be substantiay increased uness some form of externa heating is used. It must be recognised that the concrete sab temperature wi generay be ower than the air temperature, often as much as 10 C, and this wi govern the rate of cure. As the resin fooring cures, in condensing conditions moisture vapour may condense onto the surface and cause booming, a permanent couding of the surface. Cod, wet or humid conditions, and imited air fow, can resut in condensation on the part cured foor. The workabiity, open time, cure deveopment and return to traffic wi be significanty affected by ambient conditions. Mixing equipment Sow speed dri ( rpm), such as MM17 * Mixing padde, such as MR2 60B * * A too number references reate to Refina Ltd The Atro Mosaic system is designed to be aid at a nomina mm thickness.

4 Product instaation Using a sow speed dri and padde thoroughy mix the base coour for 30 seconds. Pour a of the hardener into the pre-mixed base and mix for a further 2 minutes. Excessivey vigorous mixing shoud be avoided as this can ead to undesirabe air entrainment. If the mixing area is not adjacent to the aying area the time required to transfer the mixed materia wi reduce the open instaation time. Remember to aways use the correct PPE. Pour a the mixed materia into roer tray. Using either a ow-oss medium pie synthetic roer, or dense foam rubber squeegee, distribute the materia eveny and uniformy to fuy coat the surface. Finish using a roer to ensure that a uniform and even coverage is achieved. Fuy pre-mix the fakes unti they are uniformy distributed, prior to binding the foor. Wearing spiked shoes immediatey fuy bind the wet Atro Tect with the fakes. Care must be taken to competey obiterate the wet Atro Tect with the knowedge that as this is high buid coating some of the fakes wi be fuy absorbed into the coating. When finished go back and over bind areas where the fakes have become overy absorbed into the Atro Tect. NOTE it is very difficut to scatter fakes across a foor eveny; a fu bind is the ony way to get even coverage of fakes. Aow the system to cure for a minimum of 18 hours at 20 C, but no onger than 24 hours at 20 C. Remove a excess fakes by brush and vacuum. Take care at this stage to fuy remove any oose fakes. The system must be seaed with Atro Tect standard cear. Ensure the surface of the resin screed is contamination free and a oose fakes are removed and thoroughy vacuumed as necessary. Pour the contents of the hardener into the base unit, and using a sow speed dri and padde thoroughy mix the contents for 2 minutes. Appy the Atro Tect standard cear to the system using a dense poypropyene foam squeegee or short nap roer, taking time to ensuring that a the fakes are covered. Ro the surface with a short nap synthetic roer to remove a excess and eave to cure for not onger than 24 hours at 20 C. Mix and roer appy the foowing Atro Tect standard cear coat(s) to eave a uniform cosed fim across the foor where a excess is removed. Faiure to remove excess may affect the sip resistance and appearance of the finished system. The Atro Mosaic standard matt and Atro Mosaic vertica matt variants incorporate a third coat of Atro Tect standard cear and a fina Atro Sea water based matt to achieve a cosmetic matt finish. The appication of a singe coat of Atro Sea water based matt can be appied not more than 24 hours at 20 C foowing the fina sea. Pour the contents of the hardener into the base unit, and thoroughy mix using a sow speed dri and padde for 2 minutes. Appy a very thin coat using a short nap synthetic roer appying the product to the foor from a paint tray. Heavy appication of this sea wi resut in an opaque appearance of the finished foor; therefore care is required in its appication. Ensure good air-fow and ventiation to assist with cure. Enough time shoud be given to aow the Atro Sea water based matt to reach its fu chemica cure. Physica drying of the surface aone is not indicative of the fu cure properties incuding wear and chemica resistance. Joints The spacing of movement joints must be determined by the design of the subfoor. A ive movement joints in the subfoor must be continued through the resin fooring. In a instances the type and positioning of movement joints shoud be agreed at the design stage between a parties concerned. Pease refer to Atro or FeRFA s Guide to the Specification and Appication of Synthetic Resin Systems for further guidance. A joints shoud be fied with Atro Expand fexibe jointing compound. Pease see Atro Expand datasheet for further information. Protection Whist of an extremey durabe nature these foor systems must be thoroughy protected from the rigours and abuse that exist during the ongoing contractua works. The resin foor shoud reach fu chemica cure in 7 days at 20 C. Untreated fet paper wi suffice as protection from ight traffic, however if protection is required from other trades then the foowing protection option shoud be considered. Where heavier access is required then a more suitabe medium to take the oadings, such as shuttering py or Correx by Cordek, shoud be paced on top of the untreated fet paper. The resin system shoud have cured for at east 48 hours prior to pacing the protection. No poyethyene sheets, inseed-treated hardboard, print or dyed card shoud be paced in contact with the resin surface. A joints in the protection medium shoud be taped, and a accidenta spiages shoud be recovered immediatey by remova and reinstatement of the protection. Damage wi occur to the system if ignored.

5 Ceaning (during instaation) A toos and equipment shoud be reguary ceaned using Atro Sove EP to reduce buid up and maintain the quaity of the instaation. Avoid contamination of the resin surface with sovent as this may cause ocaised boom to occur. Ensure that the correct PPE is worn at a times. Disposa Due diigence must be adopted if accidenta spiages occur. Recover using inert absorbent granues, transferring into a suitaby marked container. Disposa of a empty containers and accidenta spiages shoud be in accordance with the oca waste disposa authority. Ceaning guidance Optimum sip resistance can ony be maintained with reguar ceaning. The texture of the surface wi require mechanised ceaning with an Atro Unipad or the use of a ong-handed scrubbing brush; mop ceaning wi not be effective. Steam ceaners and / or hot pressure ceaners shoud not be used on the foor or was. A cod / ambient pressure washer may be used if required, but the pressure shoud not exceed 1400psi. Warm water wi offer improved ceaning, but the water temperature shoud not exceed 60 C. Sweep or vacuum the foor to remove debris For norma ceaning, diute an akaine detergent such, as Atro Cean 44 or simiar, by 1:40 in cean water Aternativey, diute by 1:20 for infrequent heavy ceaning Liberay appy the water and detergent soution to the foor, scrubbing with a deck scrubber or sow-speed (< 400rpm) scrubbing machine and Atro UniPad or simiar Pay particuar attention to areas where residues may accumuate, such as interna corners of perimeter coves and around coumns etc If possibe, aow the detergent soution to remain on the foor for severa minutes to break down deposits, but not sufficienty ong to aow the soution to evaporate Remove the soution by wet vacuum recovery and foow this with a fresh water rinse, or rinse the soution into drains if permissibe It is important that a detergent residue is removed from the textured surface of the foor. Detergent may become sippery which affects safety, or sticky which attracts and hods more dirt AtroCean 44 and Atro UniPads are avaiabe through Resins Saes Desk.
