Applying Water Based Polyurethane

Applying Water Based Polyurethane

***Nylfoam Applicators are NOT appropriate for use with Forna flooring products***

Applying water based polyurethane loba 2k at over a finished cork floor requires the appropriate applicator. The Loba WS 2K requires a high end, painter’s roller with a low-nap micro-fibre. We do NOT recommend “applicators” other “micro rollers” for the Loba WS 2K.

NO SUBSTITUTES!

Always wash new applicators with mild soap and water – rinse well and let dry

WARNING: Water based Polyurethanes have very short “working edges” of 10 – 15 minutes!
If you find you are running into “lap marks” then STOP APPLICATION. You are either working too slow OR YOU ARE WORKING THE POLYURETHANE TO THIN!

Contact your Forna Flooring representative while you are waiting for the floor to dry!

Wait for floor to dry. Lightly sand the lap marks (220 grit paper) and begin application from where you left off. Once the floor has been coated once, allow floor to dry. applying water based polyurethane loba loba 2k at second coat of polyurethane. The best “cure” for lap marks is sanding + re-application.

Glue down cork tiles must be allowed to “set” or cure x 24 hours before application of finish.

A floating floor cork floor can be finished once the floor is installed. Professional floor layers will normally let a floating floor “settle” for a few days before applying water based polyurethane. This allows the floor to get any “extra” expansion/contraction out of the way before the sealant is applied. It is during this “resting” time that any “installation errors” will be caught!

***If your floating floor looks like it is buckling or “lipping” around the edges of any of the planks DO NOT applying water based polyurethane. These problems are a good indication that the floor was laid incorrectly. Application of polyurethane will only make the problem worse, and make the “lipping” permanent – there is no cure for a cork floor that is showing signs of buckling and has been coated in polyurethane. Let the floor settle or remove the planks and re-install.

Floor preparation:

Sweep or vacuum the floor to remove the most amount of grit and sand. Then follow this up with “tack clothe” (water dampened – no chemicals) and then allow the surface to properly dry.

Using a Painter’s Tray:

Prepare the polyurethane as per container instructions – paying careful attention to “shake” or “stir” instructions.

***If you shake a “stir only” product, you will get excess frothing that will leave bubbles in the finish.

Pour enough polyurethane into the tray to finish the amount of flooring you have (use the “square feet per gallon” as the measure; eg 300sf of space requires ½ gallon of high-end polyurethane) into the painter’s tray.

Starting in the corner furthest from the exit, begin “cutting in” the edge of the floor (soft bristled 2-4inch painter’s brush will do well) that you are about to work. Roughly a 4 foot length on each edge of the floor will do for a start.

***DO NOT “Edge in” too much flooring! You will run it “lap mark” issues and will have to stop work!

Saturate the entire roller with polyurethane making sure to squeeze out the “extra”. Your roller should be saturated but not dripping. When working with a roller, you will roll on the product in one direction. Start at your “start” edge beside you and rolling away from you it to the wet “cut edge” of the perpendicular wall facing you. Continue, cutting in the edge in front of you and rolling on polyurethane until you reach the opposite wall.

***REMINDER: YOU HAVE 10-15 MINUTES TO GET BACK TO YOUR “START WALL”

Moving quickly back to the starting point, cut in the “starting” edge (another 3 -4 feet) with the brush and immediately begin to roll on the next row.

Continue in this way until the floor is completely covered. Resist the urge to “go back over” spots that have older than 15 minutes! If you go over a partially dried area, you will create “Lap marks” that will require sanding before the finishing coat can be applied.

Allow the finish to dry before applying the next coat. Be aware that most manufacturers suggest 2 coats per day. Always read and follow the label of the product you are using.

Water based Polyurethanes have cure rates of 5-7 days. During the curing time, only light traffic in stocking feet can access the floor. NO RUGS, NO FURNITURE, NO PETS are allowed onto the floor until the floor has achieved a full cure. Even if the floor looks cured, it may not be. Always err on the side of caution and allow extra time before animals are allowed on the finished floor.

If you have any questions, please contact your Forna Flooring expert before continuing with your project.

Direct Pour method:

Pouring small amounts of the polyurethane onto the floor’s surface is one of the fastest methods to apply any finish. This method is normally used by professionals or experienced DIYers who have site finished more than one floor. If you are not familiar with the procedure, please refer to the “Painter’s Tray” instructions.

Starting from the corner that is furthest from the exit, pour a 4-5 foot long line of polyurethane from the container (roughly 6 – 8 inches from your starting edge). Use a soft bristled 2”-4” painters brush, cut in the edges of the floor (roughly 4ft on the start edge and 5-6 ft on the edge facing you).

Saturate your roller using the line of polyurethane on the floor – squeeze out any extra on the floor in the IMMEDIATE vicinity of the area you are about to work.

Roll on the polyurethane on the starting wall (your long stroke will be in the same direction as your line of polyurethane) and moving into the wet edge of the wall in front of you. Roll in one direct. As you require more polyurethane, simply pour another line from the container and continue rolling on the product until you reach the opposite wall.

***REMINDER: YOU HAVE 10-15 MINUTES TO GET BACK TO YOUR “START WALL”

Moving quickly, return to your “starting” edge, and pour another line of product, cut in a 4-5 ft length against the floors edge. Continue application until floor is finished.

Resist the urge to “go back over” spots that have older than 15 minutes! If you go over a partially dried area, you will create “Lap marks” that will require sanding before the finishing coat can be applied.

Allow the finish to dry before applying the next coat. Be aware that most manufacturers suggest 2 coats per day. Always read and follow the label of the product you are using.
