Surface Preparation
Surfaces must be clean, free from grease, oil and loosely adhering particles. All surfaces must be as flat and level as possible.
Absorbent surfaces have to be thoroughly saturated with water prior to application of first coat of Pentens T-305TH. However, no loose standing water should be on the surface before application.
Mixing
Under normal circumstances, when the full quantities of both components are mixed together, a consistent mortar will result. Mixing shall be carried out in a clean container by gradually adding the powder component to the liquid component and stirring with slow speed mixer. Use mixture within 30 minutes. 1 set of Pentens T-305TH can be added less than 1kg of water for smooth application.
Application
Dilute 1 portion of Pentens T-007 permeable primer or 1 portion of Pentens T-305TH with 3 portions of clean water and then plaster directly to the surface to be waterproofed, in order to improve the bonding.
Apply or plaster first and finish coat Pentens T-305TH to construction surface by using brush, roller of spray method. The time interval between coats shall be 4 – 8 hours, and make sure that the first layer of plastering has been dried and formed as membrane.
Coverage
- Bathrooms, terraces and balconies: 2.0kg/m2 2 coats.
- For waterproofing coating up to 1m water head: 3.0kg/m2 3 coats.
- For waterproofing coating more than 1m water head: 4.0kg/m2 4 coats
Note
-Pentens T-305TH must be applied in minimum 2 coats.
-More coats may be required in areas of extremely high infiltration.
Over coating
After the primer, Pentens T-305TH can be applying directly provided with areas exposed hot drying winds. For indoor areas, it is recommended that allow approximately 30 minutes after the primer.
For over coating with cementitious materials, allow the second coat to harden for at least 1 day prior to over coating.
For more details, please refer to our Technical Department.
Curing
For optimum performance, Pentens T-305TH should be allowed to cure for 24 hours before the finishing concrete, tiles etc and during this time precautions must be taken in order to prevent damaging to the coating.
Cleaning
Tools and equipment just can be clean with clean water immediately, after use. Hardener material can only be mechanically removed.
