|DIRECTIONS FOR USE
|Read me first:||EVERLAST® ROOFSKIN can be applied extremely easily, without the need special equipment. In order to guarantee success, we kindly ask you to read the following instructions carefully and to comply with them.
SUPERPRIMER.While the longterm adhesion capability of EVERLAST®ROOFSKIN to various substrates is excellent we recommend to apply SUPERPRIMER to all surfaces. This ensures a perfect bond under all circumstances.
ORIGINAL ACRYLIC FLEECE. This reinforcement is free from any harmful fibers and is used to ensure that any stress or movement from the roof is uniformly distributed and thereby guaranteing the sealing function of the EVERLAST®ROOFSKIN.
Tools and Equipment:
|Tools and equipment required Figure1
Rubber gloves, soft squeegees, sheepskin rollers, extension handles, knives, scissors, propane gas-torch, fire extinguisher, buckets, small trowels, shears, blister knife, stirring paddle with electric drill, sponge rubber roller for SUPERPRIMER, sticky tape.
|Storing and applying EVERLAST®ROOFSKIN||You can apply EVERLAST®ROOFSKIN the whole year round. EVERLAST®ROOFSKIN crosslinks due to the humidity of the air at temperatures of between minus 5°C and + 45°C from being a silver liquid to the silver high-performance elastomer with the superior qualities of a space suit. .
In order to obtain a uniform coating thickness and gloss, the contents of the EVERLAST®ROOFSKIN drums should have a temperature of between 20 and 25°C before application. In the cold season, please place the drums you intend to use in a warm room for three days before use, so that the required product temperature is obtained.
On site you can warm up cold EVERLAST®ROOFSKIN by opening the lid, agitating the contents with a mixer and by applying hot air to the lower third of the drum at the same time.
Do not allow naked flame to come into contact with EVERLAST®ROOFSKIN since liqiud EVERLAST®ROOFSKIN could possibly ignite under certain circumstances.
|A1. Mixing "Tacky" EVERLAST®ROOFSKIN||"Tacky" EVERLAST®ROOFSKIN is used for fleecing work at joints, upstands,absorbent surfaces, over substrate repairs and cracks.
By stirring in 0.25 kg of short fibre to half a drum of EVERLAST®ROOFSKIN , we produce the adhesive paste for fleecing work which we call "tacky" EVERLAST®.In addition to this, the tacky EVERLAST®ROOFSKIN can be used as a coating material for very absorbent surfaces.
|A2. Mixing EVERLAST®ROOFSKIN- PASTE (Trowelling mix)||EVERLAST®ROOFSKIN Paste (Trowelling mix) is used for additional coverage at details such as upstands, pipes, junctions and any area requiring a base of thick material in preparation for the two coats of liquid.By adding 2,5 kgs of short fibres little by little to half a drum of EVERLAST®ROOFSKIN produce the trowelling mix referred to as EVERLAST®ROOFSKIN Paste. This paste will not 'run' under its own weight and crosslinks perfectly to form an elastic mastic up to 600 mm thick. .
Figure4 , Figure 5 , Figure 5a
|B0-2. Surface Pre-Treatment:||WORK STAGE No. 1
Apply the first coat of "Tacky" EVERLAST®ROOFSKIN on the primed surface.
Embedd ACRYLIC FLEECE in the first coat of "Tacky" EVERLAST®ROOFSKIN
|At all joints or upstands ACRYLIC FLEECE is bedded in the fresh coating of "tacky"EVERLAST®ROOFSKIN applied at at rate of 1.0 kg/m2.
Ensure the fleece is well pressed into the liquid and that all air bubbles are removed by rolling and that all edges of the freece are secured into the coating. It is not permissible to use any other fleece or reinforcement. Allow to dry overnight.
All rounded roof upstands, projections such as hand rail posts, vent pipes and ducts must be reinforced with EVERLAST®ROOFSKIN Paste, trowel applied and smoothed over with a spreader, allow to dry for 3 to 4 hrs.
Right-angled protrusions in the roof
All right-angled protrusions in the roof, such as chimney stacks, light domes, abutments, roof walls, etc., are treated with "tacky" EVERLAST® ROOFSKIN plus ACRYLIC FLEECE as described above.
|B6. Application of the second and final top coat of EVERLAST®ROOFSKIN
||WORK STAGE No. 2
After drying overnight the second EVERLAST®ROOFSKIN coat can be applied.
Please mark an area approx. 8 x 5 (40m2) on the rooftop and spread a 20 drum of EVERLAST®ROOFSKIN evenly over this area with a soft squeegee, ensuring the top coating is well rolled into all areas, especially over uneven surfaces and any fleece reeinforcement. The entire roof should be coated in a similar way.
|B7. Expansion joints||It is essential for expansion joints to be let in, either as a trailing strip Figure 15 , Figure 15a or fill large overlaps or abutments with a spray foam filler first Figure 16 . or use a rubber plate in areas of high mechanical stress.Figure 16a
If the expansion joints are not immediately visible, the roof must be checked at the end of the winter season to look for cracks. If cracks are present, expansion joints must be subsequently let in at these points. .
|B8. Metal surfaces||Rusty sections on galvanised or steel sheet roof sections must be treated with EVERLAST®C.A.R.O.L anti-corrosion primer first before coating with EVERLAST®-ROOFSKIN. See www.everlast4steel.com
Thick rust must be removed swept away beforer treating the surface with EVERLAST®C.A.R.O.L. .
Coverage of EVERLAST®C.A.R.O.L on trapezium sheets approx. 150 g/m2. Coverage of EVERLAST®-ROOFSKIN on smooth surfaces: approx. 1 kg/m2
|B9. PU-in situ-foam surfaces||With in-situ PU foam roof surfaces, check to see if the PU foam is dry.
|B10. Corrugated sheeting||Corrugated asbestos sheeting must be dry and is always treated with SUPER PRIMER first.
Remove coarse dirt from roof surfaces before applying (sweep off). Remaining dirt, lichen, etc. is simply sealed in!
If necessary, the overlaps of the corrugated asbestos sheets can be foam sealed with single or dual component foam. (see manufacturer's instructions) or filled up with EVERLAST®ROOFSKIN Paste.
Figure 18 ,Figure 18a
Coverage of SUPER PRIMER: approx. 100 /150 g/m2
Coverage of EVERLAST ROOFSKIN ® (double coating) approx. 1 kg/m2 roof surface.
|B11. Airless Spraying||It is an advantage that EVERLAST®ROOFSKIN can be applied by spray when covering large areas.
Application details can be obtained by contacting EVERLAST COMPOSITE LTD
|C.Total coating thickness||The initial coating thickness of the hardenend EVERLAST ®ROOFSKIN film must be approx. 1,2 mm. The visible coating thickness of the EVERLAST®ROOFSKIN film nay change during its lifetime without affecting the waterproofing capability..
EVERLAST ® ROOFSKIN crosslinks perfectly in coatings up to 600 mm thick
|D.Storage stability||EVERLAST®ROOFSKIN remains stable and suitable for use for up to 12 months if unopened and stored in a cool place.
If EVERLAST® is stored for long periods in icy temperatures, the liquid product solidifies into a pasty condition.
Please store the product in this pasty condition in a warm room at 25°C to 35° C two to three days before use in order to reobtain the original liquid condition of the product.
Freezing and thawing has no detrimental effect on the quality and performance of EVERLAST®.
After opening the drum, stir the contents thoroughly before use.
|E. Manufacturer's Warranty for EVERLAST® ROOFSKIN||EVERLAST COMPOSITE LTD offers a guarantee of 12 years for the rain impermeability of the finished EVERLAST®ROOFSKIN coat in accordance with the terms and conditions of the EVERLAST®ROOFSKIN certificate.
Warranty claims will only be considered if an authorised certificate of acceptance has been issued for the finished EVERLAST®ROOFSKIN roof. In addition, the EVERLAST®ROOFSKIN work must be re-inspected by the contractor 24 to 48 months after completion of the work in order to check for hidden expansion joints etc. If subsequent tratment should be necessary, this will be done free of charge by the contractor.
The contractor is responsible for providing evidence that this subsequent inspection was carried out on the roof in question.
