1 Atro Coat standard, Atro Coat sip-resistant, Atro Coat vertica Water dispersed epoxy coating Nomina thickness 180 microns Technica and instaation data sheet September 2016 Product description FeRFA type 2 Atro Coat standard is a twin-pack water-miscibe, moisture toerant epoxy coating with a sik finish. It has been designed to toerate construction moisture and is ideay suited for use onto newy instaed cementitious substrates. With greaty reduced substrate drying time, Atro Coat variants provide a fast-track, cost-effective soution, permitting the passage of moisture vapour from the substrate, whie sti providing a barrier against contamination from operations above. It is avaiabe in a wide standard coour range with options for bespoke coours. Atro Coat sip-resistant has a the benefits of Atro Coat standard and in addition provides a degree of sip resistance through the incorporation of a micaceous minera which ighty textures the surface. Atro Coat vertica has a the benefits of Atro Coat standard and is specificay formuated for use on vertica surfaces such as coving, was and stair risers. Standard coours Avaiabe in 26 standard coours and cear, with options for bespoke coours. In common with other epoxy resin finishes, pae coours may show some cosmetic discoouration on exposure to UV ight. Non standard coours Safety Yeow, Safety Red. Safety Red, Safety Yeow and Back are intended for ine marking and sma areas of demarcation ony. Bright ighting and dark coours in particuar back wi highight any defects such as roer ines scratches and marring. For safety coours, ight or vibrant cooured coatings, a white undercoat shoud be used and additiona coats may be required. Safety Red, Safety Yeow and white are not incuded in Atro resins standard coour range. Bespoke non-standard coours wi be subject to additiona ead time and possiby increased cost. Typica areas of use Typica areas of use incude: Light to medium duty areas New buid fast-track Warehouses Storage areas Custodia areas Pant rooms Advantages Easy to appy Cost-effective Low odour Good chemica resistance Ease of ceaning 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. Chemica resistance Atro Coat variants offers good resistance to a range of commony used chemicas. However, premature 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.

Materia usage is dependent upon temperature, surface profie and porosity; the stated coverage rates shoud be referred to for guidance ony and cannot be reied upon to determine exact quantities. 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 shoud 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 Atro Coat may be appied to a variety of substrates incuding, but not imited to, concrete, poymer-modified 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 free from standing water, 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 integra damp-proof membrane and contain residua moisture not greater than 80% R.H to (BS 8203.) High and variabe substrate reative humidity wi affect the drying, hardening and goss eve of the Atro Coat. Because of their method of appication, synthetic resin foorings such as Atro Coat wi inevitaby foow the profie of the underying substrate. This wi affect the appearance and wear. 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. Efforts shoud be made to minimise day joints and optimise the open time of the product (i.e. 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. The Atro Coat system is designed to be aid at a nomina 180 micron thickness in two coats. 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% R.H. 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 airfow, 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 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 two 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 a arge roer tray. Using a ow-oss medium pie synthetic roer, distribute the materia eveny and uniformy to fuy treat the surface. Begin on the side of the main ight source and work away from the ight. Finish using a roer in the direction of the ight source to ensure that a uniform and even coverage is achieved. The area shoud not be retouched after 10 minutes as this may resut in variations of the finish. Aow the system to cure for a minimum of 18 hours at 20 C, but no onger than 24 hours at 20 C before overcoating with the second coat. If the overcoating time period is exceeded, the surface shoud be ighty abraded and vacuumed before further coats are appied. Ensure good air-fow and ventiation to assist with cure. High temperatures, strong drafts and substrate porosity can affect the apping time and can cause roer marks.

4 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 data sheet for further information. Protection Whist of an extremey durabe nature these foor systems must by 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. No poyethyene sheets, inseedtreated 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 the guidance is not foowed. 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. Ensure that the correct PPE is worn at a times. Disposa Due diigence must be adopted if accidenta spiages occur. Recover using absorbent granues, transferring into a suitaby marked container. Disposa of a empty containers and accidenta spiages shoud be in accordance with the oca waste authority. Ceaning guidance Optimum sip resistance and appearance can ony be maintained with reguar ceaning. The sip-resistant variant wi require mechanised ceaning 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. Entrance matting wi reduce ceaning requirements and shoud aso enhance the ongevity of the foor, when combined with correct maintenance.

5 Reguar ceaning regime 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 soft-briste brush or sow-speed (< 400rpm) ceaning machine with a white soft-medium pad for smooth, goss foors, or using a deck scrubber or scrubbing machine for textured foors 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, it shoud be agitated by brushing / scrubbing during this time 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 Atro Cean 44 and Atro Unipads are avaiabe through the Resins Saes Desk.

However, where Atro has no contro over the seection of its products for particuar appications, it is important that any prospective customer, user or specifier, satisfies him / hersef that the product is suitabe for the intended appication. In this process, due regard shoud be taken of the nature and composition of the background / base and the ambient conditions both at the time of aying / appying / instaing / curing of the materia and when the competed work is to be brought into use. However, as site conditions and the execution of the work are beyond our contro, we accept no resutant iabiity. Atro s poicy is one of continuous research and deveopment and we reserve the right to update our products and information at any time without prior notice. In some circumstances the customer may decide to use a high soids acryic-emusion surface dressing as a barrier ayer to ease ceaning and / or maintain goss. It shoud be noted that this wi aso reduce the surface texture and therefore the sipresistance of the foor finish. This contro of sip-resistance, in such cases, rests with those who determine ceaning regime and the appication of surface dressings.
