Best Practices for Dana Lim Acrylic Sealant 502
-
Application
Joint dimensions: The sealant can be used in joints from 0 – 25 mm width. To be apple to absorb maximum movements, however, the joint should be minimum 7,5 mm wide. Use joint back-up material in correct dimension, which is placed according to the wanted depth of the joint.
Notice: In most building applications, there will be an acclimatisation of the building materials during the first months. This will happen, after heating of the rooms. This will lead to shrinkage between the building elements, larger than the maximum movement accomodation of the sealant. Especially for narrow joints, this might lead to cracking of the joints. To repair this, the joint must be sealed again, when the building materials / elements have finally climatised.
The tip of the cartridge is cut off with a keen knife after which the tip is cut with an inclined cut, which is a bit smaller than the width of the joint. The sealant is applied using hand- or pneumatic gun.
The sealant is pressed in place and finished with a joint nail dipped in water, a wet sponge or a wet cloth, not later than 5 - 10 minutes after application.
-
Surface Preparation
All surfaces must be clean, dry, free of grease, dust and loose particles. Acrylic Sealant 502 can be used without primer on surfaces such as glass, anodised aluminium, treated wood, concrete, bricks and ceramic. Very porous surfaces should be primed with a dilution of 50 % water and 50% acrylic sealant.
-
Curing
The product cures by evaporation of water.
The joint will cure in approx. 1 – 2 days in small joints. Larger joints will require a longer curing time. The sealant will cure slower at lower temperatures and higher relative humidity.
-
Clean-Up
Uncured sealant is removed with wipes or hot water.
-
Removal
Cured sealant can only be removed mechanically.
Skin is washed with water and soap.
