Junckers Strong is a single part water based 100%Polyurethane Lacquer, ideally used on new unfinished wooden floors or newly sanded and prepared wooden flooring eg. Floorboards,Parquet Blocks, Oak Strip etc...and is suitable for domestic or light commercial levels of foot traffic.
This is a fast drying and easy to apply product, which in normal drying situations, of 20 deg C and 50% Relative humidity, will dry in approx 1-2hrs per coat, has virtually no smell and is UV stable meaning the lacquer wont yellow/discolour with age.
The above text is the standard Junckers product description.
We have used this product extensively on scores of projects and have had absolutely no problems whatsoever with Junckers Strong. This product is a direct competitor with the mighty Bona Mega, and is usually about 10-15 % cheaper to buy than Mega, but performance wise, in our opinion is every bit as good, Strong really does look tremendous when properly applied to a well prepared wooden floor.
While the product is in the mid range of the Lacquer cost scale, being a Junckers product it is easy to apply, has excellent flow and leveling properties and dries in good time as well,[dependant on site conditions]
With quality wood flooring lacquers, you get what you pay for, and what you get with Junckers Strong is a high quality product, that is virtually bullet proof, and is backed up with the Junckers name, which is synonymous with High Quality, Excellent products and considerable technical know-how.
This product is also pretty easy to apply to a properly prepared wooden floor, whether you are using a roller or a more professional 'T Bar' applicator, Junckers Strong will look superb when properly applied.
Expect to pay between £50.00-£60.00 for a 5 litre can of Junckers Strong , online retailers often have offers on, shop around to get the best deal you can.
If possible, have the central heating turned on in the room/house that the Junckers Strong is being applied into, this can help considerably with lacquer drying times.
Remember maximum hardness [being fully cured] is achieved after 72 hours
The coverage is also excellent, we get at the very least 10m2 per litre of Strong, often 12m2 + is achievable but is dependant on many things. NEVER skimp on the amount of lacquer you put down, 10-12 m2 per litre of product is an average and coverage depends on a variety of variables, for example a badly prepared floor will almost certainly need more lacquer than a correctly prepared floor - its all in the preparation.
ALWAYS carefully read and follow the manufacturers instructions.
Junckers Strong comes in a 2.5l, 5l or 10 litre can [with a filter]
and is available in 3 different sheen levels which are:-
Matt [20% Sheen] Satin [40% Sheen] and Gloss [70% Sheen]
All these finishes look superb when properly applied and it would of course depend on the choice of the end user as to what aesthetic sheen level best suits the particular area/room where that the product is being applied.
APPLICATION
We are often asked 'How many coats of lacquer do i need' - the simple answer is as many as you like, but this always relates to cost & the timeframe involved in the project. As a general rule of thumb a Professional Floor Sanding company will specify 3 Coats of Lacquer or 2 coats of Oil as standard for a domestic situation, extra coats of lacquer will be at an extra cost, anything between £4 - £6 per coat per m2 eg. For a 20m2 lounge to be given a 4th coat of lacquer should cost between £80 - £120
If in doubt just ask your Floor Sanding Professional.
Junckers Strong can be applied to a wood floor in a number of ways, a floor sanding professional will use a variety of application methods depending on the size of project, but if you are looking to apply lacquer to for example a 20m2 lounge, Oak strip, a 9" roller would be perfectly acceptable, the roller refill you need should be a 'medium pile' with the pile length being approx 8mm, a decent quality roller will have that information on the packet, use an inch and three quarter roller cage, these are more robust and just better than the cheaper inch and a half alternatives.
- Look out for a light blue line around the roller refill, this designates that the pile has been thermo fused onto the actual roller sleeve and is highly unlikely to shed hair/pile into the lacquer.
For cutting in we would recommend using a 4" Mini Paint Roller with a foam refill, these products are cheap but do the job extremely well. You don't always have to buy the manufacturers recommended products, which are normally twice the price of perfectly suitable alternatives.
Junckers recommend 2 or 3 coats in domestic situations, and 3 or 4 coats in commercial/high traffic situations.
