Sika fix/sealant: which grade ? (1 Viewer)

[Ridgeway]

Have seen that my local dealer sells sika products and he has one that is stated as a sealer (221 i think) and one that is stated as an adhesive (252 i think).

Which product is commonly used in the UK and for what purposes ?

Hi usually 512 :thumb: or 221 both good for sealing and sticking
