Part A : Part B=: 1:1.25 (By Weight)

• Approx 45 mins at 30 ° C (Touch dry)
• Approx 5-7 days for initial cure for installing overlay like tile adhesive,protective screed ,etc
• Approx 28 days for full cure

The above vary depending on ventilation,temperature,humidity,etc

Approx 60 mins (Workable time ) @ 30° C

2.5- 4 hrs depending on temperature,ventilation and humidity

The minimum recommended coverage of MasterSeal
555 IN is 0.9-1.0 kg/m2 per coat to get approx. 0.65-
0.75 mm thick wet film build. Therefore, for two coats,
the material requirement is 1.9-2.0 kg/m2. Actual
coverage depends upon the method of application,
the texture and porosity of the surface.

Surface Preparation
Surfaces should be structurally sound, clean, and free from cement laitance, loose particles. Oil, and grease,
mold release agents curing compound, or any other contaminant shall be removed by wet grit blasting, high pressure water jetting (approx. 150 bars) or such other effective methods.
Fill surface irregularities such as blow holes, honeycombs etc with our repair mortars to achieve a smooth and level surface.
Saturate the prepared substrate with clean water before applying SikaTop®-555 Seal

Mixing
Mechanical mixing is necessary. A slow speed (300-600 rpm), heavy duty electric drill with a wing type paddle is recommended. Place half to two thirds of Part A (white liquid) in the clean container supplied. Keeping the mixer running, add Part B (powder component) slowly and steadily. Add the remaining liquid and mix for at least 2 minutes until a
homogeneous lump free consistency is

Installation Of Coating
It is extremely important that the area being treated is shaded from direct sun and wind to prevent rapid drying of the coating.Apply SikaTop®-555 Seal evenly using a block brush. or by a notched trowel, onto the prepared surface, to give a continuous film. In case of large areas
SikaTop®-555 Seal can be spray applied using a worm-gear type of spray equipment.
Apply at least two coats with an average wet film thickness of 1 mm each. To avoid pin holes, apply the second coat at right angles to the direction of first.Ensure that no air is entrapped in the membrane during application.If during the application the mix stiffens, discard it and
prepare a fresh mix for application. Do not apply on external surfaces if rain is anticipated within 3-4  hrs.

Curing
Slow drying of SikaTop®-555 Seal membrane ensures homogenous curing and SikaTop®-555 Seal must be protected against rapid drying due to high
temperatures or wind. No further curing treatment is required but moist/spray curing can be done for 3-5 days 

Protection

It is recommended to not leave the coating exposed and protect it with an overlay like tile adhesive,protective plaster,brickbat coba,etc for long term durability
