Application:

Surface preparation: the joint edges must be clean,all oil, dust, dirt, and any other materials that may be used before must be removed. Water affects the sealant so joint edges must be dry and sealant  must protected from water unless the chemical hardness occured. Sealant can be applied without primer application. Polyethylene wicks must be used for filling to avoid adhesion of  sealant to the bottom of  joint edges. This gives ability for two way movement. Wick’s diameter should bigger than 20-25% of joint edge’s diameter.Width and deep of the edge should not be less than 5mm. Up to 15mm; the width size of the edge should be equal to its deep size. For wider joint edges, the deep size adjusted to 20-25mm. For hand applications; place the sealant into the gun and inject the sealant into the joint without causing any air bubble.
