MIXING:

 

 



 

Mix and use one complete unit at a time.  Do 

not sub-divide. 

 



Gun grade is supplied in base & catalyst in 

separate units. 

 

Mix for 5 - 10 minutes using a suitable paddle 



fitted to a 500 rpm electric drill moving the 

paddle completely through the mass of the 

material.   

 



Add the complete contents of the catalyst from 

its container and mix thoroughly, into the base 

using a palette knife. 

 



Failure to completely disperse catalyst 

throughout the base compound will result in 

uncured sealant. Once mixed  

MasterSeal GG 470 should be used 

immediately. 

 

APPLICATION

 

 



MasterSeal GG 470 is formulated to be 

applied using a sealant gun but may be 

applied by trowel if required. 

 



Sealant guns are fitted with conical nozzles 

which can be cut to suit the joint width. 

 

The sealant should be gunned into the joint 



using an even trigger pressure, cleaning the 

nozzle occasionally to avoid contamination.  

Deep joints should be filled in two or more 

runs, to prevent air entrapment. 

  Once the sealant has been applied, a small 



timber spatula, soaked in soapy water, should 

be used to compact the sealant into the joints 

and to achieve a smooth polished finish.  Any 

masking tape which has been applied should 

be removed before the sealant cures. 

 

Mixing and application equipment should be 



cleaned immediately.
