Sikalastic® 632 is the perfect combination of technology and performance, providing the ultimate in waterproofing of outdoor roof surfaces. With pure polyurethane as the main ingredient, this product not only prevents water penetration but also ensures long-term flexibility, durability and elasticity.
With its quick and easy application, Sikalastic® 632 becomes the first choice for sealing roof surfaces. In liquid form, this product reacts with air humidity on its own and coagulates rapidly, forming a durable film. This not only prevents the ingress of rainwater and environmental moisture, but also effectively seals the crack.
Unlike many other solutions, Sikalastic® 632 not only stops at forming a waterproof membrane, but also builds a strong bond on surfaces. This creates a continuous membrane, without joints, making waterproofing more perfect than ever.
What is the use of Sikalastic® 632 waterproof paint?
Sikalastic® 632 represents the ultimate waterproofing solution for various areas during new construction or repair, including:
1. Waterproofing for flat or pitched roof structures.
2. Waterproof protection for balcony and terrace areas.
3. Roof deck waterproofing has many intricate details and shapes, including drainage pipes, light doors or other details.
4. Protect the roof deck from water ingress, helping to prolong the service life.
Sikalastic® 632 paint features
1. Resistance to penetration of plant roots, preventing damage from natural elements.
2. Quick drying time, saving construction time.
3. Single component product form, can be applied at ambient temperature.
4. Waterproof material completely resists the effects of chemicals.
5. Ready to use without complicated mixing process.
6. Create a continuous waterproof membrane without joints, creating durability.
7. Hardens based on air humidity (MTC), creating effective waterproofing.
8. Good heat resistance, helping the product to ensure stability in temperature variations.
9. Perfect reinforcement system for intricately detailed roofs or pipes through the floor.
10. Effective in repelling rainwater almost immediately after being applied.
11. Allows steam to escape, helping to protect the "respiration" for the building foundation.
It can be said that Sikalastic® 632 not only helps to protect the building from water penetration, but also provides outstanding benefits for the construction and maintenance of buildings.
Advantages of Sikalastic® 632 . waterproof paint
Sikalastic® 632 is an excellent choice for roof deck protection and has the following significant advantages:
1. Economic efficiency and long service life
Sikalastic® 632 waterproof coating not only helps to protect the roof deck from deep infiltrations but also helps to prolong its life. This results in reduced maintenance and repair costs in the future.
2. High elasticity and environment-friendly
The product has high elasticity, which helps to resist the usual temperature variations and maintains its elasticity even at low temperatures. At the same time, the low volatile organic matter (VOC) content ensures environmental friendliness and human health.
3. Evaporates water and is suitable for tropical climates
The permitting of water evaporation combined with a high solids content makes Sikalastic® 632 suitable for tropical climates where humid environments are frequent.
4. Good adhesion and easy to re-apply
Good adhesion to the substrate makes it easy to re-apply when needed, without causing peeling of the old paint.
5. Simple and flexible in use
Sikalastic® 632 requires no complex mixing, which simplifies use. Furthermore, the diverse reinforcement system makes it applicable to a variety of locations and conditions.
6. Suitable for a variety of surfaces
Not only suitable for horizontal surfaces, it is also suitable for vertical surfaces. In addition, this waterproof paint is not affected by rain immediately after application.
7. Support for background breathing
Sikalastic® 632's ability to allow the substrate to breathe ensures that no heating or torch is required to ensure good performance.
8. Non-toxic and good flame retardant
The product has no toxic substances and has good fire resistance, ensuring safety for users and the surrounding environment.
With all the above advantages, Sikalastic® 632 waterproof coating is a reliable choice to protect and prolong the life of your roof.

Instructions for using Sikalastic® 632 waterproof paint
1. Waterproofing for roof surface:
. Use Sikalastic® 632 to create a waterproof coating for the roof. This coating helps to stabilize the roof surface, resist UV rays and prolong the life of the roof deck structure.
. Apply 2 coats of Sikalastic® 632 on all types of surfaces such as concrete, metal, fibro ciment, mortar and tile.
2. Reinforced waterproofing:
Sikalastic® 632 is an effective waterproofing solution for both new construction and repair projects. Suitable for surfaces that are resistant to loads and light travel loads.
3. Notes on construction:
. Do not apply Sikalastic® 632 to damp surfaces or to surfaces in constant contact with water.
. In the case of a ventilated surface, make sure the surface is completely dry before applying the product. Perform this process when the surface temperature reaches a low level.
. During application, if the temperature rises, be careful to avoid creating "bubbles" due to enhanced water evaporation.
. In severe cases, use Sikalastic® Primer and be sure to use this product with work safety measures. It is recommended to assess all potential risks before commencing work.
4. Usage restrictions:
. Do not use Sikalastic® 632 for indoor applications.
. Avoid applying directly to the XPS sheet.
. Do not place the product near the air duct of an operating air conditioner.
5. Construction method:
. Sikalastic® 632 can be applied by brush, roller or sprayer. Especially effective when using brushes in hard to reach places.
. Wait for the first coat to dry before applying the next coat.
6. Other Notes:
. The product can cover itself.
. On oiled paper, use a full reinforcement system or reinforcement sheet such as Sika® Reemat Premium from Sikalastic® Fleece 120 to cover seams or overlays.
. Materials such as soft asphalt or volatile materials may be placed under the coating.
. To meet different driving load requirements, use suitable systems. For more detailed information, refer to specific instructions.
. Avoid applying cementitious adhesives or products directly to Sikalastic® 632 surfaces (e.g. grout).
. Do not use salt or anti-caking agents between Sikalastic® 632 coatings, as this may affect product elasticity and adhesion.
. Sikalastic® 632 is resistant to soils and common cleaning solutions in the environment, and meets chemical resistance requirements.
