1. Requirements:
1.1. Requirements for labor protection work |
– During application, workers must wear full labor protection (hat, clothes, shoes, glasses, mask, and gloves).
|
1.2. Requirement for moisture |
– Substrate moisture content < 18%. – Maximum relative air humidity 85%. – Min. substrate temperature 13ºC. – Max. substrate temperature 39ºC. – Construction areas require good ventilation.
|
2. Mixing:
2.1. Mixing KERASEAL WB50 |
– Include composition A and composition B. – Using specialized mixer, approx. 600 rpm with a suitable mixing paddle. – Add the composition B to the composition A and mix a further 3 minutes until homogenous (may take a longer depending on weather conditions and equipment).
|
2.2. Mixing KERASEAL WB10 |
– Material includes 2 components: Composition A and Composition B. – Using specialized mixer to mix the composition A within 3 minutes (may take a longer depending on weather conditions and equipment). – Add the composition B to the composition A mix a further 3 minutes until homogenous.
|
3. Application steps - 1 primer and 2 coatings system.
3.1. Surface cleaning and treatment |
– The surface ensures no dust, dirt, oil.
– Surface is grinded by specialized machine with suitable sandpaper.
|
3.2. Applying KERASEAL WB50 |
– Using long-hair roller to spread KERASEAL WB50 on the cleaned surface. – Applying by roller frequently ensuring uniform coverage of the material to be applied to the surface. – Do not apply primer too thick or to create puddles will cause cracking and blistering. – Allow to dry 8 hours before patching, surface treatment or apply the next steps. – The cracks on the surface must be filled by KERACRETE NS50.
|
3.3. Applying the basecoat KERASEAL WB10. |
– Spread the mixed KERASEAL WB10 on the area to be applied with short-hair roller. – Apply by roller several times and in 2 perpendicular directions, ensure the uniform of material on the surface. – When finishing the application, make sure that the basecoat completely cover the below primer and the color is relatively uniform. – Allow to dry at least 8 hours before apply the next steps.
|
3.4. Applying the topcoat KERASEAL WB10 |
– After the basecoat completely dries, the cracks on the surface must be filled by KERACRETE NS50. – After the patching positions dry, apply 1 coat on these positions to ensure the color is homogeneous before apply the topcoat. – Use the scrubber with suitable sandpaper, sanding the entire surface of the basecoat to create roughness and remove impurities. – Spread the mixed KERASEAL WB10 on area to be applied by short-hair roller. – Apply by roller several times and in 2 perpendicular directions, ensure the uniform of material on the surface. – The topcoat must ensure the coverage, the uniformity in gloss and color. – Allow to dry at least 24 hours before light traffic and 72 hours before using.
