RESIBLOCK F.R.I

On new work ensure RESIBLOCK F.R.I is installed concurrent with the installation of the kiln dried sand on a daily basis. DO NOT WAIT UNTIL THE CONSTRUCTION IS COMPLETED BEFORE APPLYING THE SEALER.

CONTAINER SIZES

RESIBLOCK F.R.I is available in 25 litre containers.

COVERAGE

First coat 1.8 m2/litre
Second coat 3.0 m2/litre

Coverage can vary depending on type of paver and depth of joint penetration. Accurate application rates are essential to achieve full technical benefits.

SUBSTRATE/SURFACE CONDITIONS

The surface should be clean and free from oil, algae, dust and traffic film. Temperature must be above 3o C and below 30o C. Application outside of this temperature range may be possible, but please refer to our technical department prior to application. Substrate and jointing sand must be dry. Jointing sand that contains moisture will prevent bonding and stabilisation of joints. Do not use if rainfall is forecast within 8 hours of project completion.

Ensure that the sand does not protrude from the base of the chamfers, if the sand is not properly removed, it may be picked up by the application tools.

PREPARATION

On new work all that is usually required is a good sweep with a stiff broom, however if the surface has become partially weathered or contaminated, low pressure wash to remove all debris. For very soiled areas or excessive weed infestation – see section "Refurbishment".

For successful use, optimum performance and maximum penetration ensure joints are well filled to the bottom of the chamfers with clean, compacted kiln-dried sand, complying with BS 6717 or equivalent. (See notes on substrate conditions re sand removal and moisture). Coarse jointing sand will significantly reduce spread rates.

RESIBLOCK F.R.I must be installed immediately following final compaction, however where this is not possible, or where there is an anticipated delay, paver joints should not be filled with kiln dried sand. This would allow final joint filling on the same day that the surface is to be sealed. The jointing sand thereby being completely dry, allowing for optimum absorption of RESIBLOCK F.R.I

Application to poorly prepared pavers particularly in respect of dampness can result in inadequate joint penetration, paver adhesion and discoloration.

REFURBISHMENT

Inevitably existing constructions will have severe weed infestation and traffic film build-up, which would need to be dealt with in the following manner.

The entire paved area is treated with commercial weed killer six weeks prior to cleaning. If necessary this process is repeated three weeks prior to cleaning (usually required if significant rainfall was apparent after the first application). Upon installation of traffic management systems, operatives would manually remove all dead weed and grass growth. (This work needs to be meticulous.)

The surface would then be pressure washed using a traffic film remover if necessary. At the end of the process once again the entire area would be treated with a commercial weed killer.

At this stage localised repairs to damaged pavers would normally take place. As soon as the substrate and jointing sand was dry (subject to weather conditions) application of the RESIBLOCK F.R.I sealer as detailed below can commence.

NB It should be noted that when contractors quote for this work they would normally expect the following two items to be supplied and paid for by the client:

(a) Traffic management.
(b) Supply and connection to water hydrant including standpipe key etc.

EQUIPMENT

RESI-ROLLERS and RESI-SCUTTLES.

METHOD OF APPLICATION

RESIBLOCK F.R.I can be used straight from the container without thinning or addition of a reactive agent; it must not be diluted. However being aliphatic based, it is temperature sensitive and as such if stored at temperatures below 10degrees C, the polymer may tend to settle out of the solvent, as such ensure contents of container are thoroughly mixed.

An area approximately 1m by 8m should be marked out and 5 litres of F.R.I applied by RESI-ROLLER. The material should be applied using the roller horizontally to the kerb. Sufficient material should be worked into the joints so it will initially fill the chamfers (ultimately to be completely absorbed). Surplus F.R.I should be rolled off the surface and into the joints to ensure maximum performance.

When the first coat has become palm-print dry a second coat is applied to the entire area, this time roller application should be vertical to the embankment. Using the roller in opposite directions in this manner will ensure that the entire area is properly covered.

METHOD OF APPLICATION FOR REFURBISHMENT

RESIBLOCK F.R.I is applied in the same manner as indicated in paragraphs 1, 2 & 3 above. However as the cleaning process would have inevitably removed the majority of the reflective Ballotini beaded surface, it will be necessary to use 'RESIBLOCK F.R.I HV' for the second coat. Being a high viscosity and hence more thixotropic material, it would allow a coating of Ballotini beads to be added to the majority of the white paved area, this is done simply using the broadcast method, whilst the F.R.I HV is still wet.

CURING PERIOD

Rapid initial cure will take place depending on ambient temperature, humidity and block porosity; 1-4 hours can be expected. Immediately the surface is dry the paved area can be opened to traffic but full catalytic cure must be allowed to take place (72 hours) if the pavers may be susceptible to vehicle overrun.

STORAGE

Containers should be stored under cover and be protected from extremes of temperature. Partly used containers should not be stored. Any remaining traces of material in used drums must be cured by leaving the containers open; and in dry conditions, by putting water into each container.

SHELF LIFE

RESIBLOCK F.R.I (unopened containers), has a shelf life of 6 months.

CLEANING TOOLS AND EQUIPMENT

RESIBLOCK F.R.I cures rapidly when exposed to atmospheric moisture, to give a film that can only be removed with great difficulty. For this reason it is recommended that all equipment be cleaned immediately using RESICLEAN. Do not use other solvents as unknown synergistic reactions may take place. Wash with water and detergent afterwards. RESICLEAN is also effective in the removal of splashes and spillages’ of uncured sealer

HEALTH AND SAFETY GUIDELINES

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

No smoking or naked flames 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 it can be considered innocuous. Do not clean hands with RESICLEAN as solvents tend to de-fat skin that can lead 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 and 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.
