The MARITRANS is a transparent, hard-elastic, one component, aliphatic polyurethane, high-solids coating, used for long-lasting waterproofing. This high-technology coating is UV-stable, non-yellowing, weather stable, alkali and chemical resistant and even after aging it remains transparent and elastic.
The MARITRANS protects and waterproofs mineral surfaces against water penetration, frost, smog and acid rain. Aged and oxidized plastic surfaces look more transparent after coating with MARITRANs. It waterproofs damaged glass surfaces and protects of glass fragments in case of breaking.
The MARITRANS is used also as a transparent binder resin
for sandcarpet floor coating applications, especially in exterior applications where flexibility and UV stability is required.
The MARITRANS 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.
Advantages
Simple application (roller or airless spray).
When applied forms seamless transparent membrane.
UV stable
Resistant to water and frost.
Crack-bridging
Provides water vapor permeability, so the surface can breathe.
Provides excellent weather resistance.
Maintains its mechanical properties over a temperature span of -40C to +90C
Provides excellent adhesion to ceramic tiles and glazed surface
The waterproofed surface can be used for domestic pedestrian traffic.
Resistant to detergents, oils, seawater and domestic chemicals
Even if the membrane gets mechanically damaged, it can be easily repaired locally within minutes
E Used as a binder resin for sand carpet applications, provides high elasticity and flexibility, making it ideal for applications on balconies and terraces.
Over 10 years of positive feedback worldwide

Application as a Transparent Waterproofing Coating.
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%. New concrete structures need to dry for at least 28 days. Old coatings, dirt, fats, oils, organic substances and dust need to be removed. Activate (prime) and degrease glass and glazed surfaces with the MARISEAL TILE-PRIMER. Possible surface irregularities need to be smoothened. Any loose pieces and dust need to be thoroughly removed. Do not wash surface with water!
ATTENTION: Surfaces with trapped moisture (e.g. trapped moisture under balconies tiles) must be left to dry completely (max. 5%moisture), before the application of the MARITRANS coating. WARNING: Do not apply the MARITRANS on ceramic surfaces with ascending nitric salts in the joints, without suitable pretreatment. Do not apply the MARITRANS on surfaces treated in the past with active silane, siloxane, silicon or other water repellents, because of expected poor adhesion. We recommend an adhesion test, if circumstances and surface history are not clear. On marble and granite please perform an adhesion test, to ensure that adhesion is proper.
Repair of cracks and joints:
The careful sealing of existing cracks and joints before the application is extremely important for long lasting waterproofing 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.
Priming (Activation of surface)
Prime (activate) non-absorbent glazed surfaces, like glazed ceramic tiles, glass and glass bricks with MARITRANS TILE-PRIMER. Apply the MARITRANS TILE-PRIMER by soaking a clean and dry cloth, and wipe the entire surface off. By this application procedure, you ensure that besides the chemical activation (priming) of the surface, the surface is getting also very effectively degreased. Change cloths often. Make sure that enough quantity of MARITRANS® TILE-PRIMER is applied on the entire surface top rimed and make sure that you do not leave any untreated spots. ATTENTION: If applied on transparent plastics (polycarbonate, polyacrylate, etc) do not use the MARITRANS TILE-PRIMER.
Transparent waterproofing membrane
Pour the MARITRANS coating onto the primed surface and lay it out by roller or by suitable teeth trowel, until all surface is covered. After 12 hours – but not later than 18 hours –apply a second layer of the MARITRANS coating, by using roller or brush. For better waterproofing and wear resistance results, apply a third layer of the MARITRANS coating. ATTENTION: Do not apply the MARITRANS over 1mm thickness (dry film) per layer. For best results, the temperature during application and cure should be between 5C and 35C. Low temperatures retard cure while high temperature speed up curing. High humidity may affect the final finish.
Finishing
If a satin matt surface is desired, apply one layer of the MARITRANS 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.
Application as a Binder Resin for Sandcarpet Coating.
Surface Preparation
Careful surface preparation is essential for optimum finish and durability.
If applied on MARISEAL 250 make sure that the surface is clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the sandcarpet coating. Maximum moisture content should not exceed 5%. Possible surface irregularities need to be smoothened. Any loose pieces and dust need to be thoroughly removed. Do not wash surface with water!
If applied onto concrete, make sure that the surface is clean, dry and sound, free of any contamination, which may harmfully affect the adhesion of the membrane. Maximum moisture content should not exceed 5%. New concrete structures need to dry for at least28 days. Old coatings, dirt, fats, oils, organic substances and dust need to be removed. Possible surface irregularities need to be smoothened. Any loose pieces and dust need to be thoroughly removed. Do not wash surface with water!
Priming
Prime concrete surfaces with MARISEAL 750 primer and broadcast silica sand while still wet.
Sandcarpet Coating
Mix the MARITRANS with colored Silica Sand (corn size 0,7-1,2mm or 2,0-3,5mm) in a mixing ratio of 1:10 (resin: sand) by weight, with a low speed mechanical mixer, until the mixture becomes fully homogenous. Pour the mixture onto the prepared surface and apply by flat trowel.
For best results, the temperature during application and cure should be between 5C and 35C. Low temperatures retard cure while high temperature speed up curing. High humidity may affect the final finish.
Packaging
MARITRANS is supplied in 20 kg, 10 kg, 5 kg and 1kg pails. Pails should be stored in dry and cool rooms for up to9months.Protect the material against moisture and direct sunlight. Storage temperature: 5-30C. Products should remain in their original, unopened containers, bearing the manufacturers name, product designation, batch number and application precaution labels.
