Which Scrim Tape Do I Need? A Complete Guide to Scrim Tape Types

White Scrim: The Everyday All-Rounder

Best for: Standard plasterboard and everyday drylining

If you’re working with standard plasterboard in a normal, dry internal environment, White Scrim is the straightforward choice.

It’s your traditional self-adhesive fibreglass scrim, designed to reinforce plasterboard joints before plastering or jointing.

Nothing complicated. Nothing fancy. It does the job it’s supposed to do.

Choose White Scrim when:

• You’re working with standard plasterboard
• It’s a normal dry internal environment
• You need a reliable everyday scrim
• There aren’t any specialist moisture or performance requirements

HD Orange Scrim: When You Want More Grip

Best for: Jobs where you want stronger adhesion and a higher performance scrim

If you’ve ever spent half your time pushing scrim back onto the board because it doesn’t want to stay put, you’ll understand why adhesion matters.

Walther Strong HD Orange Scrim has a finer, stickier mesh with 25% more adhesion than our standard scrim, along with higher tensile strength.

That makes it a good step up when you want something that grips well and gives you a stronger reinforcement across the joint.

Choose HD Orange Scrim when:

• You want greater adhesion
• You want a higher tensile strength
• You need a higher performance alternative to standard scrim
• You want a choice of widths

Basically, if standard scrim will do the job but you’d rather have something with a bit more about it, go orange.

Drylining HD Scrim: When You’ve Got a Lot of Board to Get Through

Best for: Large-scale drylining projects and faster application

Sometimes the biggest problem isn’t what scrim you’re using. It’s how much of it you’ve got to apply.

Walther Strong Drylining Scrim comes on longer rolls, giving you twice the length of a standard roll. That means fewer roll changes and less stopping and starting when you’re working your way through a large-scale project.

It can also be used with a plastering gun, helping speed up application when you’ve got plenty of joints to get through.

For a couple of boards, you probably don’t need to overthink it. For a whole development? Those saved minutes soon start adding up.

Choose Drylining HD Scrim when:

• You’re working on a larger drylining project
• You’ve got a high volume of plasterboard joints to cover
• You want fewer roll changes
• You’re using a plastering gun for quicker application
• Speed and efficiency matter on the job

Blueline Scrim: For Moisture Resistant Boards

Best for: Moisture resistant plasterboard

Working with moisture resistant board? That’s where Blueline Scrim comes in.

It’s designed specifically for use with moisture resistant plasterboards, making it the better choice where a standard everyday scrim isn’t suited to the board you’re working with.

And this is where the names can get confusing because yes, Walther Strong also has a completely blue scrim.

They’re not the same thing.

Choose Blueline Scrim when:

• You’re working with moisture resistant plasterboard
• You need a scrim suited to moisture resistant board applications
• You’re working in an area where moisture resistance is part of the board system

HD Blue Scrim: The Waterproof Option

Best for: Wetrooms, AQUA panels, cement boards and magnesium boards

Now we’re getting into the wetter stuff.

Walther Strong HD Blue Scrim is a waterproof and alkali resistant fibreglass scrim designed for applications including wetrooms, AQUA panels, cement boards and magnesium boards.

It has a tensile strength of 120 N/50mm and is designed for jobs where standard plasterboard scrim simply isn’t the right product.

So if you’re working with specialist boards in a wet environment, this is the blue you’re looking for.

Choose HD Blue Scrim when:

• You’re working in a wetroom
• You’re working with AQUA panels
• You’re working with cement board
• You’re working with magnesium board
• You need waterproof and alkali resistant scrim

Which Scrim Tape Do I Need? Here’s the Quick Answer

If you don’t fancy reading all of that again, here’s the quick version:

Pick the scrim that suits the board, environment and scale of the job rather than treating every roll as interchangeable.

Because while they might all look like mesh on a roll, they’re not all there to do exactly the same job.
