Now, before you dip your trowel into the plasticizer pot, it’s worth considering when you might not need this handy additive. If you’re working with pre-mixed mortar or a specific mortar blend that already contains plasticizer, using additional plasticizers might throw off the mix’s balance. It’s always crucial to read the manufacturer’s instructions and consult with the mortar gods (maybe they’re real!) before adding anything extra.
Conclusion:
To plasticize or not to plasticize – that is the question! Ultimately, the decision to include plasticizer in your mortar mix depends on the specific application and your requirements as a builder. If you’re striving for effortless workability, improved bond strength, and efficient curing, then adding a plasticizer might just be the secret ingredient you’ve been missing. So, why not give it a whirl and unleash the power of plasticizer in your mortar mix?
