Sikafloor 440 Level Fibre Reinforced extended information
Consumption: 20 kg will cover approximately 2.4 m2 at a depth of 5 mm
Limitations
- Always mix with clean fresh water and always prime floors as directed.
- Always apply this product whilst primer coat is still damp.
- Never exceed the quantity of water stated. This will dramatically reduce strength and cause cracking.
- Do not mix more compound than can be laid in 20minutes and never try to reconstitute once the product has set.
- On substrates where underfloor heating is in place, switch off the heating for 24 hours before, and until 24 hours after, application.
- Do not use this product below 4 °C.
- In areas where movement is anticipated, always use SikaBond® SBR+ diluted 1:1 with water rather than water. NO OTHER MANUFACTURER’S PRODUCT MAY BE USED.
- To avoid cracking/crazing, existing concrete screeds/asphalt/bitumen/bituminous coatings must be a minimum of 4 weeks old before overlaying with this product.
- As the manufacturer cannot know all the uses their products may be put to, it is the user’s responsibility to determine suitability for use. If in doubt, contact Technical Services Department.
Sikafloor 440 application instructions
Floors to be treated must be free from grease, dust and loose particles. Substrates must be porous. Always prepare floors by dampening with water then priming with SikaBond® PVA+ or SikaBond® SBR+ diluted 1 part PVA/SBR to 3 parts water to give a sound, slightly damp surface. Deep depressions and holes should be filled with a suitable repair mortar and allowed to dry.
20 kg of Sikafloor® 440 Level Fibre Reinforced will require 4.2-4.4 L of water. DO NOT USE EXCESS WATER. Always add the powder to water. This should be car- ried out by stepwise addition whilst stirring until a free flowing creamy compound is produced. Pour the mixture out into the prepared floor and allow it to find its own level. Trowel down lightly to achieve an overall thickness not exceeding 30 mm. Minimum thicknesses for a wooden substrate is 10 mm.
SAND / CEMENT RENDER
Allow at least four weeks drying before application. Dampen floors and prime with SikaBond® PVA+ diluted 1:3 with water. Mix with water as detailed above. For surfaces to be subjected to heavy foot traffic, use SikaBond® SBR+ diluted 1:1 with water rather than just water when mixing the powder.
TIMBER FLOORS
Floors must be securely screwed down at 300 mm centres. Apply SikaBond® SBR+ to the floor at a 1:1 dilution and apply to subfloor whilst the bonding coat is still tacky.
EXISTING VINYL TILES
Ensure tiles are clean and sound. Prime with SikaBond® SBR+ diluted 1:1 with water and apply floor level compound mixed with SikaBond® SBR+ diluted 1:1 with water over tiles whilst primer coat is still tacky. Allow 24 hours before applying final covering.
