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.

STRUCTURE OF THE COATING: From the foregoing it should be clear that only the application of the three structural elements:

ADHESION (=> by means of SUPERPRIMER )
STRESS DISTRIBUTION (=> by means of the rot-proof ACRYLIC FLEECE)
SEALING (=> by means of the longlasting, high-performance elastomer EVERLAST®ROOFSKIN )

guarantees the long term weatherproofing of the felted or mastic asphalt roofs.This is why we prime the surface with SUPERPRIMER first, apply a coat of EVERLAST®ROOFSKIN with embedded ACRYLIC FLEECE and finally topcoat with a second layer of 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.
Figure2 ,Figure3


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
  • B0. All surfaces must be swept clean of all debris and loose materials including any surface finish chippings, using mechanical means if required.Any excess moisture must be dried from the surface.Figure 6 Repair all areas of damage and blisters with EVERLAST®ROOFKIN Paste , trowelled into place and smoothed over with a spreader.
  • B1.Felted or Mastic Asphalt roofs: Any blisters in the existing waterproofing must be star cut and the roof felt rolled back from the centre to expose the bitumen. The bitumen in the blister is then heated with a gas torch, and the blister edges are tapped back flat again. Figure 7 ,Figure 7a
  • B2. To prevent migration of tar oils and plastisicers from the existing surface into the EVERLAST®ROOFSKIN layer ALL AREAS must be barrier coated (primed) using SUPERPRIMER at a rate of 0,15 kg /m2. Allow the primer to dry one hour.Figure 8
    On all new bitumen-felts : Apply SUPERPRIMER and let dry overnight!



Apply the first coat of "Tacky" EVERLAST®ROOFSKIN on the primed surface.

  • B3. 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® can be used as a coating material for very absorbent surfaces.Figure 2, Figure3
  • B4.The first batch of "tacky" EVERLAST®ROOFSKIN is prepared and - where necessary - ,an approx. 1 mm thick coat applied with a sheepskin roller on the primed surface.Coverage is approximately 1kg/m2 for this work stage. In practise apply a strip of approx. 20 to 30 cm wider than the strip of FLEECE so that an overlap is created.
    Figure 9 , Figure 9a



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.
Figure 10 , Figure 11 Figure 11a


Rounded protrusions
Reinforcement of all upstands, projections etc is carried out before or during work stage no. 1

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.

EVERLAST®ROOKSKIN Paste is made by mixing 2,5 kg of SHORT FIBER , little by little, with approx. 12 kg (half a drum ) of EVERLAST®ROOFSKIN to form a trowelling paste.(See details above under section A2) .
Figure 4 , Figure 5 , Figure 5a

This paste is applied around the rounded section in a cavetto-type form (a concave wedge).
Figure 12 , Figure 12a , Figure12b , Figure12c , Figure12d , Figure12e , Figure12f , Figure12g
Coverage approx. 1,6 kgs EVERLAST®ROOFSKIN plus 0,4 kg SHORT FIBER per meter


Right-angled protrusions in the roof
Reinforcement of all upstands, projections etc is carried out before or during work stage no. 1

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.
Cover with ACRYLIC FLEECE to a height of at least 20 cms and 20 cm surrounding the object. The ACRYLIC FLEECE acts as a reinforcement of points subjected to extreme loads or movement.

Do not forget to treat all surfaces first with SUPERPRIMER!
Figure 13 , Figure 13a , Figure13b , Figure13c , Figure13d


B6. Application of the second and final top coat of EVERLAST®ROOFSKIN

After drying overnight the second EVERLAST®ROOFSKIN coat can be applied.

Coverage in this work stage no. 2 is approx. 0,5 kg/m2.Thus the total coverage of EVERLAST®ROOFSKIN (first plus second coat) is approx. 1,2 kg/m2

When all preparatory work from step no.1 has been done and the existing joints, expansion joints, etc. have dried then the second coat EVERLAST®ROOFSKIN is poured on and spread left and right with a soft squeegee. to obtain a uniform thickness, the surface is rolled crosswise with a sheepskin or lambs-wool roller immediately afterwards.Figure 14, Figure 14a

At least 0.5 kg/m2 of EVERLAST®ROOFSKIN must be applied during this work stage.

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

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.
  • 1st possibility: The PU roof surface is still smooth, i.e. no moisture has yet been absorbed by the upper layer .In this case, the whole PU roof surface must be coated with SUPER PRIMER. SUPER PRIMER is applied with a sponge rubber roller.

    Coverage of SUPER PRIMER: approx. 150 g/m2.

    After this pretreatment one ACRYLIC FLEECE reinforded coat of "tacky" EVERLAST®ROOFSKIN is applied plus one top coat of pure EVERLAST®ROOFSKIN

  • 2nd possibility: The PU roof surface is rough, i.e. the upper layer is already absorbing moisture.
    Then the surfaces are not primed with SUPER PRIMER, but EVERLAST®ROOFSKIN is thickened by adding 2-3% of short fibre and this so-called "Tacky" EVERLAST®ROOFSKIN is directly rolled onto the PU roof. By thickening it with short fibre, the Roof Skin cannot sink into the fine cracks in the roof surface.

    After this pretreatment one ACRYLIC FLEECE reinforced coat of "tacky" EVERLAST®ROOFSKIN is applied plus one top coat of pure EVERLAST®ROOFSKIN

    Figure 17


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.

Figure 19 ,Figure 20 ,Figure 20a ,Figure 20b ,Figure 20c ,Figure 20d

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.
