Here is an easy solution based on .NET PDF (https://freepdf.codeplex.com/) to add text watermark to PDF documents with following code snippet:

using System.Drawing;
using Spire.Pdf;
using Spire.Pdf.Graphics;

namespace DrawTextWatermark
{
class Program
{
static void Main(string[] args)
{
PdfDocument doc = new PdfDocument();
doc.LoadFromFile(@"..\..\Sample1.pdf");

foreach (PdfPageBase page in doc.Pages)
{
PdfTilingBrush brush = new PdfTilingBrush(new SizeF(page.Canvas.ClientSize.Width / 2, page.Canvas.ClientSize.Height / 3));
brush.Graphics.SetTransparency(0.3f);
brush.Graphics.Save();
brush.Graphics.TranslateTransform(brush.Size.Width / 2, brush.Size.Height / 2);
brush.Graphics.RotateTransform(-45);
brush.Graphics.DrawString("This is text watermark", new PdfFont(PdfFontFamily.Helvetica, 24), PdfBrushes.Violet, 0, 0, new PdfStringFormat(PdfTextAlignment.Center));
brush.Graphics.Restore();
brush.Graphics.SetTransparency(1);
page.Canvas.DrawRectangle(brush, new RectangleF(new PointF(0, 0), page.Canvas.ClientSize));
}

doc.SaveToFile("TextWaterMark.pdf");

}
}
}

You can create a pdf file first by an imaging SDK .Then create watermark to the pdf files.If you have an imaging SDK,then everything would be easy.
