ONLY apply fiberglass strip"horizontally (ACROSS the piping sump, not up and down.) <br /> The completed glass job should be air-free, seamless and ripple-free as shown in Fig. H.9.3. <br /> Fig. H.9.3 <br /> Fig. H.9.1 Fig. H.9.2 <br /> Roll over the fiberglass mat many times with a Chamfer roller (provided) on the OUTSIDE JOINT <br /> to make sure it is cleanly adhered to the fiberglass piping sump walls. Run the roller up and down to <br /> force any air out from under the fiberglass strip. (Fig. H.9.2) <br /> H.10 - Repeat Steps H.4 to H.9 and apply fiberglass strips to the INSIDE JOINT of the piping <br /> sump. (Fig. H.10.1) For the INSIDE fiberglass strips use a Barrel roller to apply the strips to the <br /> curved surface. (Fig. H.10.2) <br /> Fig. H.10.1 Fig. H.10.2 Fig. H.11 t <br /> H.11 - Use a Chamfer roller to carefully rollover the applied fiberglass strips to run out any air <br /> bubbles. (Fig. H.11) <br /> H.12 - Allow at least 4 hours at 75 Degrees to cure. During this time, continue on to other sumps. <br /> H.13 - When all fiberglass applications have cured, sand them down Fig. H.13 <br /> lightly with air-sander or roughly with coarse 40 - 60 grit sandpaper all <br /> the way around the piping sump to knock down all excess fiberglass 'hair' " <br /> and material. (Fig. H.13) <br /> H.14 - Mix resin and apply with paint roller, completely covering the <br /> fiberglass material all the way around the piping sumps. Roll resin generously <br /> with paint roller. DO NOT USE PUTTY KNIFE or other scraping tool.The resin needs to be applied generously and evenly. (Fig. H.14) NJ <br /> H.15 - Now install any other equipment in the piping sump(s) that was not <br /> installed yet.
