British Standard 5212 :1990 — types N, F and FB.
U.S. Federal Specification SS-S-200E :1984.
Colpor 200PF retains its movement accommodation of 25% on butt joints throughout the extremes of temperature, it does not harden in cold weather nor become excessively soft or pick up in hot conditions.
In trafficked areas the maximum expansion joint width should be limited to 30 mm. It is necessary to recess the level of the sealant 5 to 8 mm below the pavement surface dependent on the time of year and temperature prevailing at the time of sealing.
The width/depth ratio of the Colpor 200PF seal should be 1: 1 to 1½:1 subject to a minimum 10 mm depth of sealant (example, contraction joint: 15 mm wide x 13 mm depth; expansion joint: 25 mm wide x 20 mm depth).

Joint sealing slots in concrete should be accurately formed and must be dry, sound, clean and free from frost. Remove all dust and loose material by grit blasting or grinding. Avoid polishing the joint sides when grinding. The prepared sealing slot should be blown out with dry, oil-free compressed air.
Ensure that any expansion joint filler is tightly packed in the joint and insert a bond breaker or cord caulked tightly into the base of the sealing groove to prevent sealant adhering to the base of the slot and provide the specified depth of sealant.
Concrete joint faces should be primed with Fosroc Primer 20 or Primer 19.
Decant sufficient primer into a clean dry tin for the days usage. Do not return unused primer to the supply tin at the end of the day. Prime the joint faces with a thin uniform coat of primer and allow solvent to evaporate before sealing. This takes between 30 minutes and 2 hours depending on climatic conditions. If sealant is not applied within 2 hours the joint face should be reprimed.
Where concrete joints are exposed or subject to conditions of prevailing damp or where the concrete is unusually dense or porous, (e.g. in parts of Scandinavia and Northern Europe) the use of Primer 19 is recommended. Contact the local Fosroc office for further details.
Empty the entire contents of the Primer 19 hardener tin into the base tin, and replace base tin lid. Mix thoroughly by shaking tin for 2 minutes. Prime the joint face using a clean dry brush. Avoid over application of primer causing puddles in the bottom of the joint. Colpor 200PF should be applied between 30 minutes and 4 hours after priming. If the joint is not sealed overnight the primer film should be removed by grit blasting and the joint reprimed. The mixed Fosroc Primer 19 should be applied within one working day. Do not split packs of Fosroc Primer 19.
Drain totally the contents of the curing agent tin into the large base component tin. Using a hand held, slow speed drill (300 to 500 rpm) fitted with a Fosroc paddle blade stirrer mix for 1 minute. Stop and scrape around the top of the tin to remove any remaining curing agent. Continue to mix for 3 minutes until the material is thoroughly mixed.
In cold weather, Colpor 200PF mixes more easily if stored overnight at room temperature.
Pour mixed sealant into a Fosroc G Gun after removing the nozzle end cap, pulling back the plunger rod and replacing end nozzle. In joints of 25 mm and above, the mixed sealant may be poured directly from the tin by bending the side to form a pouring lip. Apply mixed sealant so that the finished level of the seal is recessed below the trafficked surface as specified.
Clean equipment immediately after use with Fosroc Equipment Cleaner. Remove mixed material from the hands with ‘Swarfega’ or similar industrial hand cleanser.
