1 Atro Grip 6mm sip-resistant Sovent-free, epoxy finish Technica and instaation data sheet September 2016 Product description FeRFA type 4 Atro Grip 6mm sip-resistant variant is a muti-ayer epoxy resin system providing a textured surface. It can be used in heavy duty wet areas where there is an increased risk of sipping. The variant comprises Atro Fow 3mm standard variant in conjunction with Atro Grip aggregate C52 and cooured finishing sea coats of Atro Tect standard variant. Standard coours Atro Grip 6mm sip-resistant variant is avaiabe in 25 muti-cooured decorative finishes. Bespoke coour systems require a minimum ead time and acceptance of a sampe. In common with other epoxy resin finishes, pae coours may show some cosmetic discoouration on exposure to UV ight Typica areas of use Heavy duty wet areas Packing areas Workshop areas Warehousing Advantages Range of coours Good chemica and stain resistance Fuy bonded to the substrate Exceent impact resistance Provides seamess foor finish (substrate joints must be cut through) 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 Grip 6mm sip-resistance offers 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 screed. 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 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 Grip may be appied to a variety of substrates incuding, but not imited to, concrete, poymer-modified cementitious screeds, terrazzo, 25mm marine-grade pywood (consut Atro for further guidance). 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. The substrates shoud achieve 26N/mm² compressive strength (BS EN ) and surface tensie strength 1.5N/mm² (BS EN ). Substrates must incude an integra effective damp-proof membrane and contain residua moisture not greater than 5% by weight (75% R.H.) to BS 8203 (see Atro Proof for instaations above 75% R.H.). Because of their method of appication, synthetic resin foorings such as Atro Grip 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 the 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. 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 Grip foor system is designed to be aid at a nomina 6 mm thickness. Atro recommend that stainess stee mixing, aying and appication toos are used in this process. Meta transfer from mid stee toos may resut in discoouration of the screed which wi be unacceptabe to your customer. This wi be particuary noticeabe with pae coours, pease contact Atro for further guidance. 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 between 10 C and 25 C. It is not advisabe to mix and ay epoxy resin products outside of that range. 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 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 * Forced action mixer (stainess bades), such as RM65 * Stainess mixing vesse, such as RM65 drum * * A too number references reate to Refina Ltd Priming the substrate In order to achieve a uniform finish, prevent bubbes and maximise substrate adhesion a primer shoud be used. An Atro primer shoud be seected which is suited to the instaation, and appropriate for the nature and moisture content of the substrate (seek further guidance from Atro.) For substrates with greater than 75% RH BS 8203:1996 an effective damp-proof membrane shoud be aid such as Atro Proof. If Atro Proof is used this may be instaed instead of a primer coat. The appropriate Atro primer shoud be appied in accordance with the technica and instaation data sheet. Do NOT seed the primer with aggregate, experience shows that this can ead to pinhoes from entrapped air. Ensure that the substrate is we seaed and that a hungry areas are addressed before proceeding to insta the system. If the over-coating time period for the primer is exceeded, the surface shoud be ighty abraded and vacuumed before further coats are appied.

4 Product instaation Using a sow speed dri and padde, thoroughy mix the base coour for 30 seconds unti uniform. Pour a the hardener contents into the base bucket and mix thoroughy for a further 90 seconds. The aggregate shoud be added graduay into the pre-mixed binder, whist continuing the mixing action, and mix for a further 2-3 minutes. Excessivey vigorous mixing shoud be avoided as this can ead to undesirabe air entrainment. Care shoud be taken to ensure that any materia adhering to the sides, bottom and corners of the mixer is thoroughy bended in. Care shoud be taken to ensure the mixing vesse is kept free of any buid-up of contaminants which coud fa off and contaminate the foor. 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. Decant a of the contents of the mixing vesse onto the foor and spread to the desired depth using a cean stainess stee trowe or a pin rake set at the desired depth. Spike roer the area immediatey. Wearing spiked shoes immediatey fuy bind the wet Atro Fow with the aggregate. Care must be taken to competey obiterate the wet Atro Fow observing the aggregate guide coverage of 6kg/m 2 or unti the surface is fuy binded. Some of the aggregate wi be absorbed into the coating therefore more aggregate maybe required with changing substrate profies and temperature. When finished, go back and over bind areas where the aggregate has become overy absorbed into the Atro Fow. Care shoud be taken not to throw the aggregate too cose to the surface of the resin system in order to avoid unsighty cumping of the aggregate on the surface. The system must be seaed with two coats of Atro Tect standard variant, cooured coat. Ensure the surface of the resin is contamination free and a oose aggregate 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 variant from a paint tray taking time to work the coating into the surface. Ro the surface with a short nap synthetic roer. Faiure to remove excess may affect the sip resistance and appearance of the finished system. Leave to cure for not onger than 24 hours at 20 C. Mix and roer appy the finishing sea coat from a paint tray to eave a uniform cosed fim across the foor where a excess is removed. Do not food sea the Atro Grip variant. Faiure to remove the excess may affect the sip resistance and appearance of the finished system. 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, faiure to do so wi resut in ive cracks being refected through the resin finish. 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. 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 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. 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 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.

5 Ceaning guidance 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 1:10 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 Atro Cean 44 and Atro Unipads are avaiabe through the Resins Saes Desk.
