Preparation
Laying laminate: Preparation
Laying laminate flooring is child's play. However, it is important that you properly prepare all materials and steps. The following gives you step by step laying instructions. You should first clarify on which sub-floor you want to lay your Krono Original laminate flooring. Because the individual floorings are not suitable for every type of sub-floor.
Sub-floor for laminate flooring
Laying laminate on screed
The floor must be absolutely level, dry, clean and firm. It is very important to sand down and fill any unevenness of more than three millimetres over one metre. You must use PE foil as a moisture barrier.
Laying laminate on wooden planks
Loose planks must be fixed and unevenness smoothed out to ensure a flat, firm surface to lay on. Lay the Krono Original laminate flooring at right-angles to the lengthwise direction of the wooden planks. You may not use PE foil on wooden sub-floors.
Laminate on wooden boards
Loose wooden boards must be fixed and any unevenness levelled out. The boards must be firmly connected to the sub-floor so that there is no creaking later.
Laying laminate on PVC or linoleum floorings
This type of old floorings must be removed.
Laying laminate flooring on hot water underfloor heating
Please ask a heating specialist you trust to heat your floor until it is dry. They have the necessary skills and records. A surface temperature of 25 degrees Celsius is advisable; you should never exceed 28 degrees Celsius. You must remove old floorings.
Residual moisture
The screed should never exceed the following residual moisture values:
1.) Cement screed: With underfloor heating 1.8 percent CM; without underfloor heating 2 percent CM.
2.) Anhydride screed: With underfloor heating 0.3 percent; without underfloor heating 0.5 percent CM.
Before laying laminate: Preparation checklists
A.) Tools checklist
You should have the following tools ready to hand at all times when laying your Krono Original laminate flooring:
- Spacer wedges
- Circular saw with sintered carbide chamfered tooth sawblade or keyhole saw with fine sawblade or handsaw
- Angle for undercutting the doorframes
- Folding rule, pencil
- Fitting aid
- Tapping block (for laying Top Clic)
- Hammer (at least 300 g for laying Top Clic)
- Transmitted sound underlay (for floorings without S.A.S.)
B.) Materials & accessories checklist
- Precise measured data of the room size
- Krono Original laminate flooring
- Clickdicht/ Clickguard / one tube is sufficient for ten square metres of laminate flooring
- Skirting boards
- Round edge, transition and edge profiles
- Fixing clips (30 clips per pack of Krono Original flooring)
- Vapour barrier layer
- Foam sheeting
Please also note that additional transmitted sound insulation is necessary for laminate floorings without Sound Absorb System. Under certain circumstances you may also need Clickguard or a comparable joint seal, joint sealing compound and glue/bonding agent.
