PRODUCT DESCRIPTION

RESIBLOCK ULTRA is a UV stable urethane based low viscosity pre-polymer surface sealer and jointing sand stabiliser designed specifically for concrete block paving. Its penetration and bonding comes about through solvent evaporation, polymerisation being effected by atmospheric moisture. It incorporates a completely unique moisture curing system. Its main function is to provide a wet-look, colour enhancing, anti-detritus coating with a high order or resistance to Ultra Violet light.

FEATURES

Single component - fast cure, ensures rapid re-use of the facility
Provides significant colour enhancement
Highly attractive sheen is imparted to surface
Anti detritus coating allows for economic removal of chewing gum, food & beverage stains etc.
Penetration brought about by solvent evaporation
Polymerisation effected by atmospheric and residual moisture
Can be applied all year round (see application information
Suitable for most types of semi-drycast block paving
Demonstrates outstanding UV tolerance
Greatly exceeds ASTM D 2370 (elongation test) - fully elastomeric.
Proven to withstand temperatures in excess of 200 degrees C

HIGH QUALITY AESTHETICS ENHANCED

JOINTING SAND REMAINS IN PLACE UNDER THE MOST ARDUOUS CONDITIONS, INCLUDING HIGH VELOCITY WATER FLOWS (GRADIENT/EMBANKMENT) AS WELL AS MAINTENANCE PRESSURE WASHING. RENDERS THE JOINTS TOTALLY BONDED AGAINST THE GROWTH OF WEED AND GRASS SPORES.

THE SYSTEM

Special Properties
Maintains performance life of pavement.
Yields significant whole life cost savings and reduces interim maintenance.
Cleaning 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:-
  • Wide joints
  • High porosity
Use in high visibility situations
Fields of Application
HOTELS
GOLF CLUBS
LUXURY VILLAS AND RESIDENCES
PAVING REQUIRING FREQUENT CLEANING
HIGH PROFILE SHOPPING MALLS
PRESTIGE RESTAURANTS
AESTHETICALLY SENSITIVE AREAS
Limitations of Use
Clay pavers, PIC, Engineering Bricks, Quarry Tiles and Marble. May reduce SRV to an unacceptable level (accordingly the use of an anti-slip aggregate should be considered).

GENERAL TECHNICAL DATA

Coverage
2.5 & 5.0 sq. mtrs litre per coat (2 coats required) 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 degrees C, the polymer may tend to settle out of the solvent, as such ensure contents of container are thoroughly mixed.
Flash Point
45 degrees C
Can Sizes
5l cans and 25l kegs
RESIBLOCK ULTRA

APPLICATION INFORMATION

1 Make sure the surface and jointing sand is THOROUGHLY DRY and free from dirt.
2 Ensure that RESIBLOCK ULTRA is only applied when there is no risk of rain within the next 12 hours.
3 Do not apply in extremes of temperature (below 3o C or above 30o C). For temperatures above this range please consult our Technical Dept for specific application procedures
4 Ensure paving is thoroughly swept and that no jointing sand remains in the chamfers.
5 Apply to surface using the RESIBLOCK ROLLER
6 Allow first coat to become palm print dry and immediately apply the second coat (the same day)
7 Accurate application rates are critical to ensure full surface and joint sealing .
8 For surfaces that are considered to be a critical safety issue, RESIBLOCK ULTRA can be specified having an anti-slip aggregate added between the coats
9 A MINIMUM of 3 hours and a MAXIMUM of 24 hours between the first and second coats must be allowed.
10 Avoid walking on the sealed area for 3 hours after application and do not allow vehicular over-run for 48 hours.
11 ALWAYS WEAR PROTECTIVE GLOVES AND GOGGLES. NO SMOKING. WEAR A MASK WHEN WORKING CLOSE TO THE SURFACE. Please refer to current MSDS.
12 All uncured ULTRA on tools should be cleaned immediately using RESICLEAN.

HEALTH & SAFETY

PVC gloves and protective clothing/face shield must be worn, plus use of a barrier cream on exposed areas of skin, as uncured RESIBLOCK ULTRA may be considered a hazardous material.

No smoking or naked flames to be allowed, as RESIBLOCK ULTRA 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 ULTRA in the presence of foodstuffs. Once fully cured RESIBLOCK ULTRA 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.
