Depends on the mix ratio used. 

All substrates (new and old) must be structurally sound, dry, free of laitance and loose particles and clean of oil, grease, rubber skid marks, paint stains and other adhesion impairing contaminants.

In a bonding slurry coat:

Blend ordinary Portland cement into neat SikaLatex®-600 and mix with a trowel or a suitable mixer attachment in a slow speed drill (400-600 RPM) until a smooth lump-free slurry is produced. Do not overmix.

Dry screeds:

Mix 1 part of cement with 3 parts of screeding sand. Prepare mixing liquid comprising 1 part of SikaLatex®-600 to 2 parts of water.

Mix the materials together to the required consistency. Do not overmix.

In a render key coat:

Dry mix 2 parts of coarse sharp sand to 1 part of ordinary Portland cement. Add the mixing liquid consisting of equal parts SikaLatex®-600 and water until a slurry consistency is obtained. Do not overmix.

For modifying renders:

Dry mix 1 part of cement with 2 parts of render sand (0 - 4 mm). Prepare mixing liquid of 1 part of SikaLatex®-600 to 3 parts of water.

For larger areas use a forced-action mixer of the rotating drum, pan or trough type, adding the dry-mixed mortar to the mixing liquid until a cohesive mass suitable for trowel application is obtained. 

Small quantities can be thoroughly mixed by a suitable paddle attached to a powerful electric drill. Do not overmix.

For patching and repair mortars

Dry mix 3 parts of clean sharp sand (0 - 6 mm) with 1 part of ordinary Portland cement. Prepare the mixing liquid by blending equal parts of SikaLatex®-600 and water together.

For large areas, use a forced-action mixer of the rotating drum, pan or trough type adding the dry-mixed mortar to the mixing liquid until a dry consistency is obtained.

Small quantities can be thoroughly mixed by a suitable paddle attached to a powerful electric drill. Do not overmix.

Bonding slurry coat:

Apply the mix only to a clean, prepared, sound surface which has been pre-dampened but has no free-standing water. Work the slurry well into the surface with a brush or broom.

Do not allow the slurry to dry ou - apply the mortar or concrete whilst the slurry is still wet.

Dry screed:

Apply and cure screed according to local specifications and site practice. SikaLatex®-600 will aid the curing of the screed; prevent drying shrinkage and stop dusting.

Render key coat:

Ensure that the surface has been prepared to a clean, sound condition free from any surface coating, algae, foreign matters or any other product which could affect the bond adversely. The slurry is brushed vigorously into the pre-dampened surface after removing any free- standing water. All pores and voids are filled with the mix and stippled or heavily textured.

The best results are obtained with a broom. Leave to harden overnight (at +20°C) before rendering.

Render:

Always apply the mix to a prepared surface, preferentially a render key coat, which has been dampened but has no free-standing water. Apply the mix using standard plastering techniques; avoid exceeding the maximum designed depth of application. For a smooth finish, the best results are obtained with a stainless steel trowel.

Do not over trowel.

Patching and repair mortar:

Apply the bonding slurry as described earlier to the prepared patch or repair areas. If there is steel reinforcement in the repair, this must also be coated with the slurry. Never allow the slurry to dry out. The mixed material must be firmly pushed into place and compacted with a trowel or float in layers not exceeding 20 mm. Successive layers can be placed once the initial set has taken place. This mix is not suitable for feather edging since the minimum recommended depth required is 10 mm.

 
CURING

The best results are obtained from mortars modified with SikaLatex®-600 if they are damp-cured for 24 hours and allowed to dry out gradually.
Do not use curing compounds!

Tools can be cleaned with water while still wet. Once the material has cured, it can only be removed mechanically.
