EVERLAST®ROOFSKIN provides a permanent elastic, seamless sealing layer for long-term waterproofing of roofing systems on the following building types :
  • factory and storage sheds
  • office buildings, schools, hospitals, etc. ,
  • residential estates, bungalows, garages, annexes, etc.

Repairs of corrugated asbestos roofs

  • Full surface coating means that asbestos roof surfaces are completely and permanently sealed, putting an immediate stop to asbestos particles being washed away.
  • Carcinogenic asbestos fibres can no langer spread into the air, rain or ground water.

Repairs to bitumen roofing felt roofs:

  • Treatment with EVERLAST®ROOFSKIN liquid roofing system seals corroded areas,ruptures and hairlines cracks.
  • Any subsequent new cracks are reliably absorbed by the permanent elastic properties of the material.
  • Awkward details and penetrations i.e. all roof upstands, and projections such as hand rail posts, roof parapets and ducts are protected against water ingress .
  • Forming a seamless, elastic, crack bridging membrane EVERLAST®ROOFSKIN encapsulates the substrate and all details such as drains , industrial ventilation pipes and double T-supporting beams without difficulty
  • Seamless embedding of domed roof-lights especially for lightweight roofs that are prone to large thermal expansion movement.

Corrosion protection and waterproofing of concrete and sandstone structures.

  • Prevention of salt water corrosion with motor way bridges
  • Preservation of sandstone structures against acid rain in urban and industrial cites.
  • Insulation of shelters, supply areas and control engineering quarters in hospitals and military defense installations.

A silver-coloured viscous liquid which uses atmospheric moisture to trigger the curing process. This high performance elastomer can cure under ponded water withoutformation of gas and foam. Pail with 20 kg net content.

SUPERPRIMER: Yellowish low viscosity adhesion promoter, free from any styrene, toluene ,xylene or similar harmful materials. Uses atmospheric moisture to trigger the curing process.

ORIGINAL EVERLAST®ACRYLIC-FLEECE was specially developed for this job. It provides effective reinforcement at all points subjected to particular strain.ACRYLIC-FLEECE forms a strong bond with the EVERLAST®ROOFSKIN elastomer, which is impervious to weather or ultra-violet radiation - thanks to a special molecular structure of the elastomer molecule.ORIGINAL EVERLAST®ACRYLIC-FLEECE with its unique properties makes it possible to forecast a roof-service life in excess of 25 years .

TYPICAL CURING PROFILE EVERLAST®ROOFSKIN air-cures at any layer-thickness between 0.1 to 600 mm without problems.A coating of 1 to mm hardens overnight and can be further worked on the next day. During frost the total curing time may take up to 2 weeks.though this does not play a factor in the coating-quality of EVERLAST®ROOFSKIN.

SUPERPRIMER is applied in thin layers (150 bis 250 Gramm per square meter area). After 30 minutes to 1 hour they have air cured (sticky on finger ).

EVERLAST®ROOFSKIN was specially developed for difficult structional conditions and assures a permanent seal, even for hot, humid conditions or arctic ice.
Table 2
As you can see from the technical specifications, EVERLAST®ROOFSKIN is permanently waterproof but permeable to water vapour. Being highly elastic, EVERLAST®ROOFSKIN allows water to escape from the roof subsurface and thermal insulations function normally again!

Traditional plastic roof coatings rapidly lose the required elasticity when exposed to frost; they stiffen, lose their tensile strength and, in time, become brittle.This loss of ability to counteract constructional tension in the roof structure simply has to result in leaks and roof damage.

Experts know that there are very few plastic roof coatings that satisfy the technical demands set by construction engineers.They become brittle even under very slight frost. EVERLAST®ROOFSKIN has been "tailor made" for roofing conditions.Excellent low temperature flexibility has been obtained due to the specially planned molecular construction.
