Description
One 4 x 5 m piece of Blue Dolphin plastic cover foil in the gruba plus grade, which the maker prints in English on the pack as "thick plus": a thick plastic dust sheet that covers about 20 m², enough to close off one room. It keeps paint, dust, water and wet mortar off floors, furniture, joinery and glass, and sits in the protection sheets and films range at Renders World.
Where a Thick Plastic Dust Sheet Fits in the Range
Blue Dolphin makes this painting foil in five grades, all as 4 x 5 m sheets. The maker's rule for choosing between them is simple:
- Lighter grades — for covering furniture and for short painting jobs.
- Thick plastic grades — for floors and heavier work, because they stand up better to ladders and tools moving across them.
- Sensitive floors — on parquet, laminate panels or natural stone the maker advises the thick or extra thick version.
The gruba plus foil in this listing is one of the thick grades, so this thick plastic dust sheet is the one to lay on a floor that has to come out of a job clean. The maker also says plainly that one foil does not fit every task: a lighter grade is enough over furniture, a thicker one belongs on the floor, and a self-adhesive one is made for windows and trims.
What the Cover Foil Does
The maker describes the plastic foil as a physical barrier during decorating and building work:
- Stops more than paint — it also holds back gypsum dust, general dust, water, primer and the pigments of modern emulsions that can stain an absorbent surface for good.
- Follows awkward shapes — flexible polyethylene, resistant to moisture, that wraps edges, rails, chairs and furniture without splitting when it is pulled tight.
- Easy to handle — odourless, easy to cut and light over furniture; the thicker grades lie more steadily on the floor.
- See-through blue — a lightly blue, transparent film, so any shift of the plastic shows against a white wall.
The plastic is smooth and slippery to the touch and rustles a little as it unrolls. The maker sums up the line as multi-purpose, protecting against dirt and covering about 20 m² per piece.

Laying the Sheet
The maker's four steps for protecting a room before painting:
- Prepare — clean and dry the surface, so the sheet lies flat and stays put.
- Lay with spare — spread the foil with enough extra to fold over at the edges.
- Fix the edges — hold them down at skirtings, door frames and openings; a tape from the masking tapes range does this job.
- Check the corners — dust most often escapes there, so look at the seal before work starts.
Laid with spare and pressed down along the edges, a thick plastic dust sheet works as a dust screen and limits what reaches the next rooms.

FAQ
Is this grade right for covering a floor?
Yes. The maker sends floors and heavier work to the thick plastic grades, which cope better with ladders and tools, and gruba plus is one of them. For parquet, laminate or natural stone it names the thick or extra thick version.
How much floor does it cover?
One 4 x 5 m sheet covers about 20 m², which the maker gives as enough to close off one room.
What does it keep out?
Paint, water, dust and dirt, and also gypsum dust, primer and the pigments of modern emulsions, which can stain an absorbent surface.
Can I wrap furniture with it?
Yes. The maker presents the plastic foil for large items with irregular shapes, such as furniture, and for windows and doors; the flexible polyethylene follows edges and rails without splitting.
Who makes it?
