Maintains its mechanical properties over a temperaturespanof-40oC to +90oC.
Resistant to frost
Over 10 years of positive feedback worldwide.
Uses
The MARITRANS FINISH is used as a satin- matte,transparent finishing coating in combination with the MARITRANS for:
Transparent waterproofing of Balconies and Terraces
Transparent waterproofing of Ceramic surfaces
Transparent waterproofing of Glass
Transparent waterproofing of Glass-Brick walls
Transparent waterproofing and protection of Natural Stones
Transparent waterproofing of Transparent Plastics(e.g. Polyacrylate, Polycarbonate)
Transparent waterproofing and protection of Wood
Consumption
0,1 kg/m2 in one layers.
This coverage is based on application by roller onto a smooth surface in optimum conditions. Factors like surface porosity, temperature and application method can alter consumption.
Colors
The MARITRANS FINISH is supplied transparent, satin-matte

Application
Surface Preparation
Careful surface preparation is essential for optimum finish and durability.
The surface needs to be clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the membrane. Maximum moisture content should not exceed 5%. Substrate compressive strength should be at least 25MPa, cohesive bond strength at least 1.5MPa. 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 a grinding machine. Possible surface irregularities need to be smoothened. Any loose surface pieces and grinding dust need to be thoroughly removed. Do not wash surface with water!
Repair of cracks and joints:
The careful sealing of existing cracks and joints before the application is extremely important for long lasting water proofing results. Clean concrete cracks, hairline cracks, expansion joints and control joints of dust, residue or other contamination. Prime locally with the MARISEAL
710 Primer and allow 2-3 hours to dry. Fill all prepared cracks and joints with MARIFLEX
PU 30 sealant. Allow to cure.

Finishing
Apply the MARITRANS
FINISH over the cured MARITRANS polyurethane coating by roller, until all surface is covered. If high usage of the surface is expected, try to apply more product quantity. Do not apply a second layer.
ATTENTION: Apply the MARITRANS FINISH over the MARITRANS coating, 12 hours after the application of the last layer. For best results, the temperature during application and cure should be between 5 oC and 35OC. Low temperatures retard cure while high temperature speed up curing. High humidity may affect the final finish.
WARNING: The MARITRANS coating system is slippery when wet. In order to avoid slipperiness during wet days, sprinkle suitable aggregates onto the still wet coating to create an anti-slip surface. Please contact our R+D Dept. for more details.
Packaging
MARITRANS FINISH is supplied in 17 kg, 10 kg and 5 kg pails. Pails should be stored in dry and cool rooms for up to9months.Protect the material against moisture and direct sunlight. Storage temperature: 50-300C. Products should remain in their original, unopened containers, bearing the manufacturers name, product designation, batch number and application precaution labels.
MARITRANS FINISH is a satin-matte, transparent, semi-rigid, one component, aliphatic polyurethane coating, used for matt finishing over MARITRANS polyurethane coatings. The MARITRANS FINISH is UV-stable, non-yellowing, abrasion resistant, alkali and chemical resistant. It gives the surface a satin-matte look.
The MARITRANS FINISH is using a unique curing system (moisture triggered), and unlike other similar systems it does not react with moisture (moisture-cured) and does not form bubbles.
