Times are approximate and will be affected by substrate, film thickness and changing ambient conditions particularly temperature and relative humidity.
Consumption

Consumption

Consumption depends on the roughness and absorbency of the substrate.
 

Damp proofing

~4,5 to 5,0 kg/m2

(~4,5 to 5,0 mm wft)

(3,1 to 3,4 mm dft)

Waterproofing

~6,0 to 6,5 kg/m2

(~6,0 to 6,5 mm wft)

(4,4 to 4,7 mm dft)

Adhesive for boards

~2,0 kg/m2

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
Application steps

SUBSTRATE QUALITY

Substrate must be uniform, dry or slightly damp, free from dust, loose material, surface contamination, existing coatings, oil, grease and other materials which could reduce adhesion of the coating. Surface defects (>5 mm) such as blowholes, voids, honeycombing, etc. must be filled / repaired with suitable Sika® repair mortars.

SUBSTRATE PREPARATION

Surfaces must be cleaned and prepared using suitable preparation techniques to provide a clean slightly textured surface. Defects should be repaired with an appropriate Sika® repair mortar. Porous substrates must be primed using Sika® Igolflex ® P-01 or use diluted Sika® Igolflex®-101. Sika® Igolflex®-101 : Water (1:2 by weight).

MIXING

Prior to mixing all parts, mix part A (resin) using an electric single paddle mixer (300–400 rpm) or other similar equipment. Mix liquid and all the coloured pigment until a uniform colour / mix has been achieved. Add part B (hardener) to part A and mix part A + B continuously for at least 3 minutes until a uniformly coloured mix has been achieved. Excessive mixing must be avoided to minimise air entrainment. During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least once to ensure complete mixing. Mix full units only. Mixing time for A+B = ~3 minutes.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened Sika® Igolflex®-201 can be removed with Sika® Thinner C.
