DESCRIPTION

In the design of RESIBLOCK F.R.I. paving sealant the following specific considerations had to be made;

The Ballotini beaded surface of the pavers is exceptionally coarse, and as such easily retains traffic film and detritus, being particularly noticeable on white blocks. The epoxy/C.R.P. painted finish on the pavers greatly reduces the porosity normally found on standard concrete pavers, preventing the absorption/adhesion characteristic required by most paving sealers. The intensity of the white pavers dictated that any sealer had to be UV light stable. The joints on most roundabouts are filled with kiln dried sand which is either washed out by rainfall or, more usually retain moisture to provide an environment that encourages the growth of weeds and grasses. The sealant not only had to be strong enough to withstand traffic vibration but moreover it had to be able to be cleaned by a pressure washer without significant dislodgement of the epoxied Ballotini surface:

	Benefits.
•	Sand loss prevented by rainwater on the banked surfaces
•	Pavers protected from becoming stained by detritus and traffic film build-up
•	Inhibit weed and grass growth in the sand joints (which create a hazard by
	obscuring the chevron pattern)
•	Unaffected by water or ice
•	Firmly bonds the Ballotini beaded surface
•	Greatly increases safety as the pavers can be economically and frequently
	cleaned and hence maintain the reflective quality
•	Whilst designed specifically for all coloured epoxy resin/C.R.P. faced blocks
	RESIBLOCK F.R.I. can also be used on any standard concrete paver.
•	Greatly exceeds ASTM D2370 (elongation test)
•	Eliminate serious damage by freeze/thaw cycle
•	Prevent pavers from spalling, cracking and settling by heavy traffic after use
•	Unaffected by commercial de-icing salts
•	Hard wearing, durable and long lasting
•	Rapid drying characteristics
•	Ideal for both new and refurbishment projects
•	Applied by specialist contractors

	PRODUCT DESCRIPTION RESIBLOCK F.R.I. is a urethane based low viscosity prepolymer jointing sand stabiliser and surface sealer, designed specifically for Black/White Chevron block paved roundabouts. Its penetration and bonding comes about through solvent evaporation, polymerisation being effected by atmospheric moisture. It incorporates a completely unique moisture curing system eliminating the problems common to water based and solvent acrylic coatings. Its main function is to bind the particles of sand together and to the vertical faces of the paver. FEATURES • Single component - fast cure, ensures rapid re-use of the roundabout • UV stable. Ensures non-yellowing of White pavers • Penetration brought about by solvent evaporation • Can be applied all year round (see application information). • Suitable for all types of traffic islands and roundabouts • Manufactured under ISO 9002 • Greatly exceeds ASTM D 2370 (elongation test) - fully elastomeric. • Proven to withstand temperature in excess of 200 deg C • High degree of resistance to commercial chemicals. • Unaffected by commercial de-icing salts • Pavers can still be easily removed STRUCTURAL INTEGRITY JOINTING SAND REMAINS IN PLACE UNDER THE MOST ARDUOUS CONDITIONS, INCLUDING HIGH VELOCITY WATER FLOWS (DOWN GRADIENT/EMBANKMENT) AS WELL AS MAINTENANCE PRESSURE WASHING. RENDERS THE JOINTS TOTALLY BONDED AGAINST THE GROWTH OF WEED AND GRASS SPORES. MAINTENANCE ISSUES VIRTUALLY ELIMINATED.	THE SYSTEM Special Properties Maintains performance life of roundabout Yields significant whole life cost savings and reduces interim maintenance. Safety issues permanently addressed. Contributes to ‘Best Value’. Fuses seamlessly to all Interfaces. Virtually eliminates weed and grass growth in the joints. Ideal for use with pavers having:- Ballotini Beading Epoxy paints Chlorinated Rubber Paints Fields of Application ROUNDABOUTS TRAFFIC ISLAND PELICAN CROSSINGS KERBING CAR PARK DEMARCATION HIGH VISIBILITY PAVING DISABLED PRIMARY ROUTES Limitations of Use PIC, Engineering Bricks, Quarry Tiles and Marble GENERAL TECHNICAL DATA Coverage 1.8 m sq /l (first coat), 3.0 m sq /l (second coat) depending on joint width and paver porosity Cleaning of Tools RESICLEAN Drying Time 2 hrs @ 20 degrees C Storage Store under cover and protect from extremes of temperature. Being aliphatic based it is temperature sensitive, if stored at temperatures below 10 deg C, the polymer may tend to settle out of the solvent, as such ensure contents of container are thoroughly mixed.

RESIBLOCK 'F. R. I.' APPLICATION INFORMATION 1 Make sure the surface and jointing sand is THOROUGHLY DRY and free from dirt. 2 Ensure that RESIBLOCK F.R.I. is only applied when there is no risk of rain within the next 8 hours. 3 Do not apply in extremes of temperature (below 3o C or above 30o C). 4 Ensure paving is thoroughly swept and that no jointing sand remains in the chamfers. 5 Apply horizontally to the surface using a RESIBLOCK APPLICATION ROLLER. 6 Accurate application rates are critical to ensure full joint stabilisation ((typically 1.6 m sq /litre ).). 7 Wait until first coat is palm-print dry, then apply second coat vertically using a RESIBLOCK APPLICATION ROLLER. 8 Avoid walking on the sealed area for 3 hours after application and do not allow vehicular over-run for 48 hours. 9 ALWAYS WEAR PROTECTIVE GLOVES AND GOGGLES. NO SMOKING. WEAR A MASK WHEN WORKING IN CONFINED AREAS. Please refer to current MSDS. 10 11 All uncured spillages/splashes, and all tools must be cleaned immediately with RESICLEAN. SPECIAL NOTE. These application guidelines refer to newly constructed roundabouts only. Special application procedures and special materials (including RESIBLOCK F.R.I. HV) are required for refurbishment projects.

No smoking or naked flames to be allowed, as RESIBLOCK F.R.I. is FLAMMABLE. Ensure area to be treated is well ventilated. If public access is allowed, erect NO SMOKING signs and site fire extinguishers A mask of the recommended type is essential when using a paintbrush, working close to the surface or internally. Sabre or Martindale is recommended. Do not apply RESIBLOCK F.R.I. in the presence of foodstuffs. Once fully cured RESIBLOCK F.R.I. can be considered innocuous. Do not clean hands with RESICLEAN as solvents may de-fat skin leading to dermatological problems. Do not return unused material to original containers. DO NOT RESEAL or store partly used kegs. Material so stored may have poor adhesion, Carbon Dioxide may generate and put the drum under pressure, which might rupture the drum. Furthermore partial or total solidification of the sealant may occur.
