Description
Description:
Colpor 200 is a cold applied, two-part elastomeric sealant designed as an efficient cost-effective sealant for joints in concrete paved areas.
The capability of accommodating repeated and pronounced cyclic movements is retained by Colpor 200 throughout extremes of climatic temperatures.
Colpor 200 is resistant to fuel, oil and hydraulic fluid spillage, will not harden in cold weather nor become excessively soft
or pick up in hot conditions. Colpor 200 provides a high level of sealing efficiency over an extended period, reducing
maintenance costs.
Uses:
For the sealing and maintenance of joints in concrete roads, runways and hard standings. The excellent fuel resistance of
Colpor 200 makes it particularly suitable for sealing areas where fuel and oil spillage might occur such as oil terminals,
airfield hard stands and garage forecourts.
Advantages
- Cold applied – no heating equipment required.
- Fuel, oil and hydraulic fluid resistance.
- Tough rubbery seal, tolerant of climatic variations.
- Improved sealing efficiency – less maintenance.
- High movement accommodation.
- Two grades (pouring – self levelling and gun grade).
Standard compliance
U.S. Federal Specifications SS-S-200E H:1984. British Standard 5212:1990 Types N, F and FB. DTp Specification for Highway Works Dec. 1991 Series 1000 Clause 1017.
Design criteria:
Colpor 200 has movement accommodation factor of 25% in butt joints. For optimum performance, consideration should
be given to the possibility that movement accommodation will not be evenly distributed between joints provided. To ensure
the sealant operates within its stated movement capacity of 25%, the width of sealing slots should be designed accordance with the recommendations of BS6093. In trafficked areas the maximum expansion joint width shouldbe limited to 30 mm.

Specification clauses:
Where so designated on the drawing, joints are to be sealed using Fosroc Colpor 200 pavement sealant, comply
with U.S. Federal Specification SS-S-00200E, H:1984, BS5212:1990 Types N, F and FB and DTp Specification for
Highway Works Dec. 1991 series 1000 clause 1017 manufactured by Fosroc. Joints shall be prepared, and the sealant mixed and applied in accordance with the manufacturer’s current data sheet.
Application instructions:
Joint preparation
Joint sealing slots should be accurately formed and must be dry, sound, clean and free from frost. Remove all dust and
laitance by grinding, grit blasting or wire brushing. 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 at the required depth to provide the seal dimensions specified. Before sealing insert a cord or bond breaker caulked tightly into the base of the sealing groove to prevent sealant adhering to the base of the slot.
Priming
Prime joint sealing slot surfaces with Fosroc Primer 20 and allow the solvent to evaporate before sealing. The surface
should be touch dry. This takes between 30 minutes and 2 hours depending on climatic conditions. Colpor 200 sealant
must be applied within the time period of 30 minutes to 2 hours after priming before the primer film has completely reacted. After 2 hours any primed surfaces must be reprimed before applying sealant, therefore, avoid priming more work than can be sealed in a 2-hour period.
Estimating
Packaging
Colpor 200 is available in 4 litre composite packs containing base compound and curing agent in separate tins marked
Part ‘A’ and Part ‘B’. Each outer contains two, 4 litre packs. 20 litre packs are also available for machine application.
Storage
Twelve months in original containers stored in cool, dry conditions i.e. not exceeding 25o C. Storage above this temperature may reduce storage life.
