Resiflow Chemical Grade is a one coat, high build, self-levelling epoxy resin finish, which leaves a smooth, exceptionally high gloss surface, which is both attractive and easy to keep clean. This high performance formulation is usually applied at 1-2mm thick, but can be applied up to 5mm in one application. It is an ideal floor covering for durability and appearance.

Resiflow Super Gloss has very good general chemical resistance, but this has been enhanced to ‘Excellent’ for Resiflow Chemical Grade.

If slip resistance, as well as excellent chemical resistance is important, apply one coat of Watco Protecta-Coat Anti Slip (62 PTV), a clear, glossy, polyaspartic resin, over the top.

Both grades now carry CE Mark EN1504-2 and have impressive test results for hardness, abrasion, scratch and impact resistance, as well as for adhesion and flexibility, and they have an A+ VOC emissions rating with a low level of VOC.

Surface Preparation

Bare Concrete – remove surface laitance, dust and any light dirt or grease deposits using Watco Etch & Clean. Watco Etch & Clean also etches smooth, bare concrete surfaces to provide a key. Flush with clean water and allow the surface to dry. For the removal of heavier deposits of oil and grease we recommend Watco Concroff, again, flush with clean water and allow the surface to dry.

New Concrete – as a guide, new concrete should be left for eight weeks to dry; (if the application must go ahead before this, use Watco New Concrete Primer). The surface should then be prepared using Watco Etch & Clean and thoroughly rinsed away and left to dry prior to applying this coating.

Painted surfaces – abrade to remove any weak or loose paint. Check remaining paint is well bonded. Very smooth, glossy paint should be lightly abraded to provide a key. Watco Bio D can be used to remove grease and oil from painted surfaces. Watco Concroff is a very powerful degreaser for contaminated bare concrete, (do not use on a previously painted surface since it can soften paint).

Repairs – Chips and small holes in concrete which may reflect through Resiflow can be quickly repaired using Watco Concrex Fine Filler. Watco Concrex can be used for isolated bigger holes and damage. If the concrete has a generally rough surface, it would be more economical to first resurface it with Watco Flowtop rather than trying to achieve a smooth surface with layers of Resiflow.

Priming – use Watco 4 Hour Epoxy Primer on open textured, or very porous high suction surfaces, such as sand and cement screed. This provides a uniform finish and prevents air entrapment bubbles. Very smooth or power floated concrete should be primed with Watco Powerfloat Primer.

Metal – remove any rust and flaking material by disc grinding or wire brushing. Apply Resiflow immediately after preparation to the clean metal surface. Grease or oil can be removed using Watco Bio-D. Allow the metal to dry before coating.

Galvanised Metal – Watco Galvaprime must be used to prepare galvanised metal.

Mixing

• Remove all three components from the outer bucket
• Stir the contents of the coloured resin tin thoroughly, and then do the same for the clear curing agent, (scrape around the inside of the tins to remove any residue)
• Pour the resin into the outer bucket, and using a mixing blade (available from Watco) fitted to a slow speed electric drill, (do not use a high speed drill as this will pull too much air into the mix and encourage air bubbles to form)
• Start to mix while slowly adding the curing agent
• When thoroughly mixed add the fine powder blend, mixing for 2-3 minutes until uniform in colour and consistency, ensuring that all material at the sides and base are thoroughly blended together
• It is possible to hand mix small quantities, but great care must be taken
• The mixed components must be used immediately
• To assist with mixing and application, we recommend 1 person to mix continuously, whilst the other gradually adds the powder blend
• Important - once the contents of the pack have been mixed, a chemical reaction takes place which creates heat. The product should therefore be used straight away

Application

• Best results are obtained in warm (minimum of 15°C), dry conditions with good ventilation
• Application on cold surfaces can reduce the product’s ability to flow
• Working in sections of approximately 5m², pour the mixed components onto the prepared surface in ribbons and spread evenly to the desired depth of 1-2mm using a Watco Resiflow Applicator, or similar notched trowel
• The applicator has a built in depth guide which makes it easier to achieve the required thickness
• The product will naturally self-level
• Use a spiked roller to remove air bubbles and repeat a few minutes later and thereafter if air bubbles continue to form
• Application within the 5m section needs to be completed within 15-20 minutes maximum
• Do not spike roller for longer than 20 minutes or track marks will be left on the surface
• Spike rollering should extend into the previously applied section, but ensure that this has not hardened to such a degree that spiked rollering is not possible
• If a knife cut in the wet surface heals quickly, the surface is still safe to roller
• Spiked shoes, should be worn if you need to walk across the wet floor
• Do not wash or allow water to lie on the surface for at least 7 days
