PENNTROWEL 250 SB (Slurry Broadcast) and SBR (Slurry Broadcast Reinforced) Flooring Systems are multi component chemical resistant floor lining systems designed for fast installation in moderately demanding chemical service, especially where thermal shock is a concern. PENNTROWEL 250 SB and SBR may be used for renovating old concrete floors and as an overlay for new concrete floor protection. The system is ideal to protect flooring subjected to chemical spillage, fork lift traffic, impact, and abrasion. A dry inert aggregate is added to a catalyzed premium epoxy binder to yield a semi- flowable consistency. This mixture is then poured onto a suitably prepared concrete substrate and spread to 3/16 in or 1/4 in thickness, followed immediately by seeding to excess the fresh surface with a dry inert filler.
As an alternate upgrade, a 1 oz chopped strand glass mat reinforcement can be specified to be added into the primer layer to provide membrane type reinforcing under the 3/16 in or 1/4 in top wear layer. For this application, specify the SBR (Reinforced) system. A top coat may be applied if desired to either the SB or the SBR system. A non slip texture can be incorporated into the topcoat if desired by adjusting the coarseness of the broadcast sand in the topcoat. Consult specification CES-294 for complete installation details.
If the surfacing system is to be exposed to hydrofluoric acid, fluoride salts or hot caustics, a carbon aggregate filler is to be used.
