Overview:

Sika SikaMix 5 Litre 3 in 1 Render and Screed Water Resisting Plasticiser and Retarder a triple-action admixture that improves workability, reduces water penetration and retains workability for longer, helping you cover larger areas with less risk of the mix going off too quickly. Formally Everbuild 204 3 in 1 now called - Sika SikaMix 3 in 1 - As Part of the Everbuild to Sika Rebranding

Designed specifically for sand and cement renders and screeds, it also helps prevent water bleeding, lowers porosity, improves durability and helps inhibit efflorescence. Ideal for exterior rendering and screeding, it’s also well suited to roughcast and pebble-dash style finishes where a smoother, more consistent mix and improved water resistance are required.

Key Features

• Water resisting, plasticising and retarding admixture for renders and screeds

• Improves resistance to water penetration and lowers porosity

• Retains workability for longer to help complete larger areas in one go

• Air entraining and helps prevent water bleeding from fresh mortar

• Helps inhibit efflorescence and transmission of hygroscopic salts

• Improves durability in exterior render and screed applications

• Conforms to EN934-3 (Air Entraining/Plasticising Admixtures)

Applications

• Exterior sand/cement renders and screeds as a water resisting admixture

• Helping prevent water “bleed” from fresh mortar

• Water reduction to inhibit passage of salts in (external or internal) rendering and screeding

• Pebble dashing and roughcast finishes as a mortar improver

• Internal use only where appropriate (e.g., after installation of a DPC system), and always to manufacturer guidance

How to Use

• Prepare the substrate: clean, sound and free from dust, loose material, oil/grease and contamination before rendering/screeding.

• Dose at 250–500ml per 25kg cement depending on mortar class, temperature, sand quality and cement type.

• Premix with gauging water and dispense into the mix with the gauging water. Do not add directly to the dry mix.

• Avoid excessive air entrainment: do not overdose or overmix.

• Where multiple render layers are applied, scratch the previous layer to assist bond, and ensure subsequent layers are no thicker than the previous layer.

Sika 3 in 1 SikaMix Waterproofer Plasticiser Retarder 5 Litre – Key FAQs

• What does SikaMix 3 in 1 do?
  It improves water resistance, plasticises for easier application, and retards set to retain workability for longer in renders and screeds.

• What is it designed for?
  It’s intended for exterior renders and screeds, and is also used as a mortar improver for pebble dash and roughcast finishes.

• How much should I add per mix?
  Use 250–500ml per 25kg of cement, adjusting within the range to suit workability requirements and site conditions.

• Can I use it in structural concrete?
  No. It should not be used in structural concrete.

• Is it a replacement for a DPC or tanking system?
  No. It is not intended as a DPC replacement and it will not resist permanent hydrostatic pressure. For tanking applications it should be used in conjunction with a DPM.

• Does it make the finished render fully water-repellent?
  No. The final finish does not repel water; if a water-repellent finish is required, coat the render with a suitable proprietary sealer.

• Can I combine it with other additives?
  Do not mix with other additives in the same gauging water. Always premix with gauging water for correct dispersion.
