Kiilto Pro Plan Fiber

A bonded floor construction:
Ensure that the substrate is suitable for the product, e.g. Sufficiently strong concrete. The substrate must be clean, dry, free from cracks, uncoated, free from oil, grease and any other substances (such as cementitious glue) that might impair adhesion and the final result. Smooth and dense surfaces must be sanded mechanically or ground to ensure proper adhesion, if necessary. In areas of normal wear, the documented bond strength of the substrate must be 1.0 MPa at the minimum.

Required layer thicknesses:
Concrete: 3-50 mm
Lightweight concrete: 6-20 mm
Ceramics/natural stone: 3-50 mm
Chipboard: 15-50 mm*
Wood flooring: 15-50 mm*

*Thickness of chipboard must be at least 22 mm. The floorboard/structure must be sufficiently rigid. When levelling wood flooring and chipboard, the minimum thickness is 15 mm and the levelling layer is reinforced with fibreglass mesh installed with a minimum 50 mm spacing and secured to the substrate with staples.

The movement joints of the substrate:
If movement joints are required, make them into the screed layer, down to the substrate. They are placed at the same position with the movement joints in the substrate. Joint width must be 10-15 mm. There may also be alternative solutions.

A floating floor construction:
The total layer thickness must always be 30 mm at the minimum and a steel mesh must always be used with the screed (Ø min. 3 mm, 50x100 mm) or Kiilto fibreglass mesh. The reinforcement mesh is installed with min. 50 mm overlaps. The screed is separated from the substrate with e.g. a filter cloth. Larger surfaces must be divided in smaller,
separated sections.

The surface under a floating surface material must be sufficiently smooth. The surface is sanded or smoothed, if necessary. The floor must be primed with Kiilto Pro 704 BSP after levelling to prevent the floor from cracks. This may be necessary, especially if the indoor air is very dry and the screed surface has not been coated for several months.

Preparation:
Correct temperature is vital for a successful result. The substrate temperature must be min. +10°C. The temperature must be monitored and ensured well before priming. A higher temperature is beneficial for the quality and drying time. Maximum temperature +25°C during installation or drying of the screed.

Priming:
Always prime the substrate with Kiilto Primer 001 according to the instructions given in the technical data sheet. Apply primer 1-48 h prior to levelling, and always let dry before applying the screed. However, do not let the primer dry for more than 3 days, since the construction dust and other impurities may adhere to the primer coat and impair the adhesion of the screed. Note:
If the primer is applied with a so called primer pump, the primer must always be rubbed onto the substrate with a brush. Non-absorbent substrates should be roughened if necessary and Kiilto Pro Fix Primer should be used as a primer. In case of non-absorbent substrates, please contact Kiilto contact person (pumpable screeds).

Mixing:
Make sure that the screed is homogenous and consistent, fluid and free from lumps. If a stiffer product is desired (pouring), the amount of water can be reduced. Water temperature: +5...+20°C.

Application:
Kiilto Pro Plan Fiber is pumped straight from the pumping truck on the substrate in stripes. Apply a new stripe on a previous one as soon as possible, so that they blend in and form an even and smooth layer. Make sure that the width of the stripes do not exceed 10 meters. Larger areas must be divided into smaller sections. Check carefully that the drains and other penetrations are sealed properly before applying the screed to avoid clogging up the discharge pipes and having screed spilled on surrounding surfaces.

Work the screed with a notched trowel or similar tool to ensure as smooth a surface as possible. If applying several screed layers, apply primer between each layer. Let the first screed layer dry for at least 24 hours prior to priming. Check and make sure that the surface is so dry that the substrate absorbs the primer. Mixing ratio when priming a new screed layer: Mix Kiilto Pro Primer 001 in 3-10 parts of water depending on the drying conditions and the substrate’s absorbancy. Apply primer twice, if using over 7 parts of water. For highly porous concrete and lightweight concrete, prime in two coats [1:5 (1st coat), 1:3 (2nd coat)].

Semi-hardened screed is easy to mold or cut. If planning to make levellings, do not wait too long.

Drying:
The drying time of the screed depends on the substrate 's humidity, layer thickness, temperature of the structure and air and relative air humidity of the area. Effective ventilation accelerates drying.
For more information on the drying properties of the product, please contact your Kiilto pump coating contact person.

The product can be applied on concrete with RH 90%.
Note: The screed cannot withstand shrinkage or setting due to drying of the substrate.

Before installing a surface material, always make sure that the substrate structure is dry enough. The given drying times require a dry substrate, favourable drying conditions (approx. +20 ° C, RH 50%) and good ventilation. Pay special attention to the floor's humidity level with moisture-sensitive flooring materials.

To prevent the screed from too quick drying and cracking, the screed should not be exposed to draft, high temperatures or direct sunlight during the first 3 days after application.

Before turning on the underfloor heating, let the screed dry at least 1 mm / d (max. 30 mm thick levellings). Water underfloor heating with accurate temperature control can be brought up to its operating temperature gradually after two weeks. Start by raising the temperature up to +15°C or to floor's current temperature, if it is higher. After that, the floor temperature can be raised by 2 degrees every third day. If the room temperature is much lower than
the temperature of the screed, the floor temperature must be raised slower.
