Neomax® 201

DESCRIPTION
Neomax® 201 is a two-component liquid waterproofing compound based on multi-functional polyurethane resins and containing solvent. Neomax® 201 forms an elastomeric layer of an incredibly tensile strength and great elongation value. Its crack bridging properties are outstanding.

USED
Neomax® 201 can be used as the perfect waterproofing and coating layer for: 
Exposed roofs;
Terrace;
Yard;
Balconies;
Loggia;
Green balconies;
Flower-beds;
Restrooms;
Swimming pools;
Sewage tanks;
Water tank for fire extinguishment.

ADVANTAGES
Only one layer of any thickness according to specific design requirements, thus saving cost and labor;
Easy to work with paint brushes, rollers or professional sprayers;
Excellent physio-mechanical properties, namely great tensile strength and elongation;
Good adhesion to most substrate and surfaces;
The finished layer forms a seamless membrane without joints or cracks;
Incredible crack-bridging properties;
Excellent waterproofing properties;
Non-toxic if being completely dry.

SURFACE PREPARATION
Any working surfaces, either new or old, ceramic tiles or normal tiles, etc, shall be grinded by specialized grinding machines before applying waterproofing layers with Neomax® 201. Then use a blower or vacuum cleaner to make the surface completely clean. Do not use water to clean the working surface;
Carefully check the working surface after grinding. Any damages must be repaired by dedicated mortar or the mixture of Neomax® Primer P11 and cement with the ratio of 1:1;
Check the moisture content of the working surface to ensure the maximum moisture value less than 8%.

MIXING METHOD
Mixing ratio of A : B = 3 : 1 (by weight);
Open the bucket of component A, use an electric mixer to stir component A thoroughly in 2 - 3 minutes. Then pour all component B into the bucket of component A while keeping stirring thoroughly in 2 - 3 minutes to get a homogeneous mixture;
Note: During mixing time, keep the mixer arms deep into the mixture to prevent any unnecessary airflow.

WORKING
After mixing Neomax® 201, with the support of a dedicated blade, immediately apply the mixture on the working surface which is already coated with a primer layer of Neomax® Primer P11. Please refer to the updated TDS of Neomax® Primer P11 for more information and instruction;
Use spiked roller to break all air bubbles;
Apply only one layer of the approved thickness;
Theoretical consumption: 1.3 kg/m² for a primer layer of 1mm thick;
For outdoor sites, it is advisable to apply a protective topcoat layer of Neomax® Topcoat T14 which will deliver a great aesthetics, incredible anti-abrasion properties and perfect durability under any weather conditions. Please refer to the updated TDS of Neomax® Topcoat T14 for more information and instruction;
In case Neomax® 201 is covered with a screed layer or ceramic tiles, fully saturate with oven-dry silica sand (corn-size of 0.4-0.8mm) after applying Neomax® 201 for 60-90 minutes. This will help to increase roughness for better connection adhesion with other upper layers.

NOTE
Total working time shall not exceed 30 minutes (depending on the ambient temperature);
Only working in the dry and convenient weather conditions;
It is possible to use less than 50-100ml of Neomax® Thinner 201 solvent to wash the Component B then pouring into bucket A for mixing.
