Description
ISOCRYL is a one component, high performance liquid-applied, pure acrylic, waterproofing material with a new fiber reinforced formulation for extra durability. Presents excellent resistance to weather conditions. It is suitable for weatherproofing old and new building surfaces. Forms an elastic seamless vapor permeable membrane without joints with excellent resistance to humidity as well as high temperatures and UV rays.
ADVANTAGES
- Elastic, seamless, vapor permeable membrane without joints
- Excellent elasticity up to 400% and ability to follow substrate expansion
- Fiber reinforced
- Highly reflective to sun UV rays offering thermo insulation advantages
- Superior adhesion on most building surfaces
- Maintains its mechanical properties over a temperature span of -15oC to +70oC
- Excellent resistance to water & ageing
- Bridges small joints – gaps
- The waterproofed surface can be walked on
- User and environmentally friendly - waterbased
- Easy to apply (one component – ready to use material)
APPLICATIONS
- Waterproofing of rooftops and terraces
- Waterproofing of gutters, domes, cornices, ondulated panels, flowerbeds, planter boxes etc
- Waterproofing bitumen and polyurethane hard foam surfaces
- Suitable for concrete surfaces, bitumen material, wood, stone, brickwork, PVC, polyurethane foam, plaster, plasterboard, metal etc

Instructions for use
Substrate preparation
Careful surface preparation is very important for optimum finish and durability.
- The surface needs to be clean, dry, sound and free of any contamination that may harmfully affect the adhesion of the membrane.
- Maximum substrate moisture content should not exceed 6%.
- New concrete structures need to dry for at least 28 days.
- Old, loose coatings, dirt, fats, oils, organic substances and dust need to be removed by mechanical means such as a sanding machine. Possible surface irregularities need to be smoothened.
Repair of cracks
The careful sealing of cracks and joints before the application is extremely important for long lasting waterproofing results.
- Carefully clean cracks and joints from dust, grease, loose debris.
- Capillary and small cracks up to 3mm must be primed with ISOCRYL PRIMER DUR AQUA waterbased primer or ISOCRYL PRIMER DUR solvent-based primer and allow drying. Apply a layer of ISOCRYL. Immediately apply on wet surface polyester fabric (capillaries) or fiberglass tape (small cracks) 30 – 60 gr/m2 respectively and again two more successive layers of ISOCRYL.
- Cracks from 3mm to 20mm and expansion joints are primed with PRIMER PU 900 and then sealed with polyurethane sealant BONDFLEX 290LM.
- Larger cracks and holes are closed – smoothed with the fiber-reinforced repair cement mortar ISOMIX MECHANIC R4 and after the cement has dried apply polyester fabric and two layers of ISOCRYL.
- Assembly points such as water heater bases, air conditioners, stairs, antennas, etc. must be sealed with a thick layer of ISOCRYL REPAIR thixotropic, fiber reinforced roof coating and allow drying before proceeding with the application of ISOCRYL.
Priming
- Prime absorbent surfaces like concrete, cement screed, wood with solvent-based primer ISOCRYL PRIMER DUR, or water-based primer ISOCRYL PRIMER DUR AQUA. Allow drying for 2 – 4 hours.
- Prime non-porous or difficult surfaces (metal, ceramic tiles, plastics) with EPOXITE DUR AQUA.
Application
- Stir product well before use.
- Pour the ISOCRYL diluted 10% with clean water onto the primed surface and spread it using a roller or brush, until all surface is covered. You can use airless spray allowing a considerable saving on labour cost. Allow drying for 8 – 24 hours.
- Apply a second layer of ISOCRYL crossways to the first layer, diluted up to max 5%.
- For extra protection or where required a third layer may be applied.
- Surfaces can be walked on at least after 48 hours. New treated surfaces exhibit a tackiness at the beginning, which disappears in due time.
- Application of ISOCRYL must be avoided at temperatures below 8oC and above 35oC and when frost or rain is expected.
RECOMMENDATION: We recommend reinforcement of the entire surface, with fiber cloth, by applying one coat before the reinforcement and 2 coats after. On surfaces with frequent pedestrian traffic, apply a layer of DRYMAX POLYURETHANE TOPCOAT after ISOCRYL to increase abrasion resistance.
ATTENTION: Do not apply ISOCRYL over 0,5 mm thickness per layer (0,5Lt/m2). For best results, the temperature during application and curing should be between 8oC and 35oC. Low temperatures delay curing while high temperatures speed up curing. High humidity may affect the final finish. Do not apply ISOCRYL in negative temperatures or when rain or frost is imminent within the next twenty-four hours.
LIFE EXPECTANCY
ISOCRYL offers a predicted waterproofing duration of 10 years by strictly following its application instructions (substrate preparation, priming, application) using reinforcing fibernet on the entire surface: 50 – 90 gr/m2 and application of the material in at least three layers with a minimum consumption of 1,5 – 2Lt/m2 or 1Lt/m2 with an additional coat of the water-based aliphatic DRYMAX POLYURETHANE TOPCOAT. Check the quality of the surface regularly, as in case the membrane is damaged locally by dropped objects or other inappropriate use it will have to be repaired locally with the material itself.
CLEANING
Clean all tools and equipment with water and soap right after applications. Cured material can be removed only by mechanical means
