Please read the following article about working with watermark. Hope this helps you.
Working with Watermark

The main problem with inserting shape object as watermark in headerfooter object is that when we click on remove_header ribbon the added water mark is also removed . How it can be prevented from deleting watermark while removing header.

using Word = Aspose.Words;

Word.Document d = builder.Document;
    Word.Drawing.Shape wm = new Word.Drawing.Shape(d, Word.Drawing.ShapeType.TextPlainText);
        
        wm.TextPath.Text = "Watermark";
        wm.Title = "WordPictureWatermark";
        wm.TextPath.FontFamily= "Arial";
        wm.Width= 500 ;
        wm.Height= 100;
        
        wm.Rotation= -40 ;

        
        wm.Fill.Color = Color.Gray;
        // Try LightGray to get more Word-style watermark
        wm.StrokeColor = Color.Gray;
        // Try LightGray to get more Word-style watermark
        // Place the watermark in the page center.
        wm.RelativeHorizontalPosition = Word.Drawing.RelativeHorizontalPosition.Page;
        wm.RelativeVerticalPosition = Word.Drawing.RelativeVerticalPosition.Page;
        wm.WrapType = Word.Drawing.WrapType.None;
        wm.VerticalAlignment = Word.Drawing.VerticalAlignment.Center;
        wm.HorizontalAlignment = Word.Drawing.HorizontalAlignment.Center;
        wm.Left = (builder.PageSetup.PageWidth - wm.Width) / 2;
        wm.Top = (builder.PageSetup.PageHeight - wm.Height) / 2;
        wm.BehindText = true;
        wm.AnchorLocked = true;
        
        Word.Paragraph watermarkPara = new Word.Paragraph(d);
        watermarkPara.AppendChild(wm);

        foreach (Word.Section section in d.Sections)
        {
            foreach (Word.HeaderFooter header in section.HeadersFooters)
            {
                
                    if (header == null)
                    {
                        // There is no header of the specified type in the current section, create it.
                        Word.HeaderFooter h = new Word.HeaderFooter(d, Word.HeaderFooterType.HeaderPrimary);
                        section.HeadersFooters.Add(h);
                    }

                // Insert a clone of the watermark into the header.
                if(header.HeaderFooterType == Word.HeaderFooterType.HeaderPrimary)
                    header.AppendChild(watermarkPara.Clone(true));
                
            }
        }

Please note that the code example inserts the watermark into the header of document. It is Shape node and child node of Paragraph node that is inside header. When you remove the header, all the content of header are removed including watermark.

Please share your input and expected output Word documents. We will then provide you code example according to your requirement.

Input File - any document file
Output Expected output, watermark inside the file and, should not be removed while header is removing.

Added some screenshot.

Pease use the following code example with the latest version of Aspose.Words for .NET 20.9 to get the desired output.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);
TextWatermarkOptions options = new TextWatermarkOptions()
{
    FontFamily = "Arial",
    FontSize = 36,
    Color = Color.Black,
    Layout = WatermarkLayout.Horizontal,
    IsSemitrasparent = false
};
                
doc.Watermark.SetText("Test", options);

builder.MoveToHeaderFooter(HeaderFooterType.HeaderPrimary);
builder.Writeln("Some text");
doc.Save(MyDir + "AddTextWatermark_out.docx");
