£146.90 +VAT
Recommended Dosage:
Add one part of Sika-1 to 10 parts of water, which is equivalent to approximately 3% of cement content. When using very wet sand, the ratio must be increased to 1:8 or in extreme cases 1:6.
Note: Trial mixes should always be conducted to establish the exact dosage rates and water requirements per mix.
Sika-1 must be stirred slowly before use to ensure a homogeneous, lump free consistency.
Sika-1 shall be diluted in the gauging water. The dilution must be stirred slowly (to ensure a homogeneous, lump free consistency) prior to addition into the mortar/concrete mixer. It can also be added neat to the mortar/concrete mix provided that the mixture is properly mixed to achieve a homogeneous consistency.
The standard rules of good concreting practice (con-cerning production, placing and curing) are to be followed. Refer to relevant standards.
Sika-1 may be combined with many other Sika products.
Note: Preliminary testing is required to prove the compatibility. Please contact Sika technical service for more information and advice.

Fantastic customer service and fast delivery, highly recommend
Great prices and a super quick delivery turnaround. Communication was perfect aswell. So much so I’ve ordered again.
They actually answered the phone, were polite, knowledgeable and the order was delivered in full and on time. Would fully recommend both on price and service. Thank you.
BTP very helpful in supplying a pallet of floor leveller. I needed it on the Saturday, but didn’t want it sitting on the driveway for several days. I called and they recommended ordering for Thursday to give a day’s grace in case of any delivery issues. In the event the pallet arrived on Thursday as requested. Reliable and good value
